Improved optomechanical interactions for quantum technologiesOndrej Cernotik
Cavity optomechanics reached remarkable success in coupling optical and mechanical degrees of freedom. The standard mechanism relies on dispersive interaction wherein a cavity mode acquires a frequency shift proportional to the mechanical displacement. Efficient coupling is, however, often impeded by large cavity decay rates or strong heating of the mechanical element by optical absorption. In this talk, I will present two strategies to circumvent this problem. In the first one, a membrane doped with an ensemble of two-level emitters or patterned with a photonic-crystal structure is used as a mechanical element. The hybridization of the cavity mode with the membrane’s internal resonance leads to a modified response, resulting in an effective narrow cavity linewidth. I will show how such systems can be described quantum mechanically and discuss how optomechanical sideband cooling can be improved by the presence of the internal resonance. Second, I will discuss optomechanics with levitated particles and show how coherent scattering can be used to generate strong mechanical squeezing. In this system, the standard dispersive interaction is replaced by scattering of the trapping beam into an empty cavity mode. This process can result in strong, controllable coupling between the cavity mode and the motion of the particle with minimal absorption heating. I will also briefly outline how this type of interaction can be used to engineer coupling between different center-of-mass modes of the particle allowing, in principle, full optomechanical control of the particle motion.

The energy bands arise because the electron momentum is restricted to the first Brillouin zone of the crystal lattice. Bloch's theorem provides insights into the distinction between metals, semiconductors and insulators by explaining whether the Fermi energy lies in an allowed band or forbidden band gap.

Gravitational potential energy is the energy an object gains due to its position in a gravitational field and depends on the object's mass, the acceleration due to gravity, and its height. Elastic potential energy is the energy stored when an object is stretched or compressed.
Gravitation is a force that attracts two masses towards each other. Newton's Law of Universal Gravitation states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Albert Einstein later developed the theory of gravitation further in his theories of relativity. On Earth, the acceleration due to gravity is approximately 9.8 m/s2, causing objects to fall towards the ground when dropped.
The document discusses tension formula, rotational motion, torque, rotational kinetic energy, elasticity, plasticity, Hooke's law, and simple pendulums. It provides formulas for calculating tension, rotational kinematics, torque, rotational kinetic energy, elastic modulus, Hooke's law, and the period of a simple pendulum. It also includes example problems and solutions for some of the formulas.
The document discusses gravitational fields and the law of universal gravitation. It defines gravitational field lines and how they represent the gravitational field around an object. The closer the field lines, the stronger the gravitational field. The law of universal gravitation describes the gravitational force between two objects using mass, distance, and the gravitational constant. Gravitational potential energy is the energy an object has due to its position in a gravitational field and depends on mass and distance from attracting objects.

This document discusses the work-energy principle and provides examples of different types of energy. It begins by defining the work-energy principle as stating that an increase in kinetic energy of an object is caused by an equal amount of positive work done on the object. Examples of positive, negative, and zero work are then shown. The document further explains kinetic energy and provides examples, as well as explaining potential energy and giving examples. It also discusses the link between work and energy and how work done on an object changes its kinetic energy.
Gravitational fields are described by Newton's law of universal gravitation and gravitational field strength. Every object in the universe attracts other objects based on their masses and distances. Gravitational fields can be thought of as radial fields emanating from objects on a large scale, but as uniform fields on a small scale near objects. The potential energy of an object is determined by its mass and the gravitational potential of its location in the field.

The document discusses the electromagnetic spectrum, which spans over 140 octaves from low frequencies like microwaves up to a theoretical maximum frequency called the Planck frequency of 2.95 x 1042 Hz. It follows a logarithmic spiral pattern with wavelength inversely proportional to frequency. The visible light spectrum detectable by the human eye ranges from 430-770 THz. The highest measured gamma cosmic ray had a frequency of around 1023 Hz.
Neutrinos are spin 1/2 fermions that are nearly massless and without electrical charge. Only left-hand neutrinos (negative helicity) with spins anti-parallel to linear momenta are observed. Right-hand anti-neutrinos (positive helicity) exhibit spins parallel to the linear momentum vector. Neutrinos have very small interaction cross-sections and interact weakly with matter. In a geometrical model considered here, neutrinos are conceptualized as vortex rings composed of spinning Planck mass dipoles and propagate along the spin axis.
The universe exhibits a fundamental dualism of opposite pairings. The present degenerate state of duality provides a clue as to the preexisting state. The Big Bang explosion of duals of surreal infinite & infinitesimal pairings is illustrated as an unstable vacuum state catastrophe. The number of modal states and information bits increase from the initial unstable vacuum singularity. The formation of a polarizable vacuum is depicted as creation of positive & negative Planck masses with positive & negative energy density. Expansion of the universe is represented as nested Riemann spheres of complex Planck impedance analogous to a 3D Smith chart of complex electrical impedance. Nested Apollian spheres of n-multiples of the Schwarzschild radius exhibits bubble voids like "suds in the kitchen sink" mass accretion & contraction similar to that apparent in the universe at large.

The spin axis is aligned with direction of the wave vector k in either the forward or backward direction depending on helicity.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptxshubhijain836
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

A comprehensive description of the nature of light, electricity and gravity is provided in
terms of quantum wave mechanics. Detailed models include the photon as a travelling
electromagnetic wave and the electron as a closed loop standing wave formed by a
confined photon. An electron is modeled as a torus generated by a spinning Hopf link
as a result of an imbalance of electrostatic and magnetostatic energy. Electric charge is a
manifestation of a slight precession characterized by the fine structure constant. The
physical vacuum as a polarizable medium enables wave propagation and appears
ultimately to be quantized at the Planck scale. Standing wave transformations for objects
in motion are reviewed and Lorentz Doppler effects compared. The mechanism for
generation De Broglie matter waves for objects in motion is depicted including the inverse
effect of induced motion of an object by synthesis of contracted moving standing waves.
Gravity is viewed as a frequency synchronization interaction between coupled mass
oscillators. The acceleration of gravity is described by a spectral energy density gradient.
Antigravity corresponds an inversion of the naturally occuring energy density gradient.
Gravitons are shown to be phase conjugate photons. The metric of curved spacetime
corresponds to the electromagnetic wave front interference node metric. Hence, the
gravitational field becomes quantized.
