Following on from his popular book ‘Quantum Finance’ of 2004, Professor Belal E Baaquie presents, -His intriguing thesis that the economic crisis of 2008 has shown that the capital markets need new theoretical and mathematical concepts to describe and price financial instruments. Professor Baaquie uses ‘quantum’ as a metaphor to imply the use of the mathematical and theoretical concepts underpinning quantum mechanics and quantum field theory, to analyse and studying finance, clarifying that there is no Planck's constant in quantum finance. The book does not seek to re-work financial principles themselves, rather to use theoretical physics methods to address finance, with a particularly focus on debt markets, that is, interests rates, and coupon bonds.
