[2003SM/LNP-15] Lecture-15--Quantum Effects in Statistical Mechanics

Quantum effects in macroscopic systems appear in two ways. The first the energy levels are quantized. The quantization of energy levels does not need any modification in the framework. Secondly identical nature of particles constituting the system. This requires a new approach to enumerating the microstates. The microstates are not labeled by coordinates and momenta as is the case in classical theory. In quantum theory the microstates are specified by giving the number of particles for different levels.
