The theoretical basis of Arrhenius rate law which is the paradigm of thermally activated processes, in general, rests on equilibrium statistical mechanics and more generally on non-equilibrium stochastic processes. Here we present a study of quantum dynamical generalization of the expression for rate coefficient in the context of quantum non-equilibrium processes in condensed media. Brownian motion lies at the heart of activated rate processes and quantum Brownian motion as compared to its classical counterpart rests on a technically different footing. Here we develop a scheme that leads to a...

In this new textbook, a number of unusual applications are discussed in addition to the usual topics covered in a course on Statistical Physics. Examples are: statistical mechanics of powders, Peierls instability, graphene, Bose-Einstein condensates in a trap, Casimir effect and the quantum Hall effect. Superfluidity and super-conductivity (including the physics of high-temperature superconductors) have also been discussed extensively.The emphasis on the treatment of these topics is pedagogic, introducing the basic tenets of statistical mechanics, with extensive and thorough discussion of the...
