Atomtronics is the science of creating circuits, devices, and materials using ultra-cold atoms instead of electrons. It compares to electronics by using atoms in an optical lattice instead of electrons in a semiconductor, and a chemical potential difference instead of an electric potential difference. Some proposed atomtronics devices include an atomtronics battery, conductor, diode, and transistor, which function similarly to their electronic counterparts but use atoms instead. However, atomtronics is still theoretical and requires significant development to be realized practically, as atoms are slower than electrons.

5. Basic terms
• Ultra cold atoms- are atoms that are maintained at
temperatures close to 0 Kelvin (absolute zero)
• Optical lattice-is simply a set of standing wave laser,
the electric field of this laser can interact with atoms.
• Chemical potential difference- is a form of potential
energy that can be absorbed or released during a
chemical reaction.

6. • Atoms in optical lattice are super cold to
form condensates ,may form states
analogous to electron.

7. It has been concluded that atomtronics systems
provides a nice test of fundamental concepts in
condensed matter physics.While these ideas have been
modeled,they are not yet to be built.They are:
• Atomtronics battery
• Atomtronics conductor
• Atomtronics diode
• Atomtronics transistor
Atomtronics devices

8. Atomtronic battery
• Schematic of atoms in a lattice
connected to an atomtronic battery.
A voltage is applied by connecting the
one of higher(left) and another
of lower(right)by chemical potential.
• Giving rise to a current from left to right.

9. Atomtronic diode
• The atomtronic diode is a device that allows an
atomic flux to flow across it in essentially only one
direction.
• The atomic diode is achieved by energetically shifting
one half of the optical lattice with respect to the
other.

10. Atomtronic transistor
• The desired function of an atomtronic transistor is to enable a
weak atomtronic current to be amplified or to switch,either
on or off ,a much larger one and acts as an amplifier.
• By configuring the optical lattice in a manner researchers
show that it is possible to recover the characteristics of the
conventional electronic transistor in the atomic world.

11. Conclusion
• Atomtronic is still a theoritical subject,and needs lot of
development and research to make it a reality.
• It is pointed out, however that atomtronic probably won’t
able to entirely replace electronics as atoms are sluggish
compared to electron

b) provoke the candidates to walk out of the examination hall
c) try to know something from your neighbour
d) try to solve the questions as much as you know with a cool head
