Elementary aspects of probability theory will first be explained as an introduction to statistical mechanics. Next introduced are the concepts of energy levels and the number of these levels, from which the microcanonical ensemble will be defined. The introduction of canonical ensemble and its applications are the most important part of this course. Properties of heat capacity of solids and black-body radiation are explained as typical applications of canonical ensemble.
Basic ideas of statistical mechanics, canonical ensemble in particular, will be explained.
Students are expected to understand the basic concepts of statistical mechanics and thermodynamics including microcanonical and canonical ensemble. In particular it is important to be able to apply these concepts to realistic problems such as harmonic oscillator, ideal gas, heat capacity of solids, and black-body radiation.
Elements of probability theory and quantum mechanics. Microcanonical and canonical ensemble. Partition function. Debye model. Black-body radiation.
