This textbook is for undergraduate students on a basic course in
Statistical Mechanics. The prerequisite is thermodynamics. It begins
with a study of three situations
—
the closed system and the systems
in thermal contact with a reservoir
—
in order, to formulate the
important fundamentals: entropy from Boltzmann formula, partition
function and grand partition function. Through the presentation of
quantum statistics,
Bose
statistics and Fermi-Dirac statistics are
established, including as a special case the classical situation of
Maxell-Boltzmann statistics. A series of examples ensue it: the
harmonic oscillator, the polymer chain, the two level system, bosons
(photons, phonons, and the Bose-Einstein condensation) and
fermions
(electrons in metals and in semiconductors). A compact historical
note on influential scientists forms the concluding chapter.
The unique presentation starts off with the principles, elucidating
the
weîl-developed
theory, and only thereafter the application of
theory. Calculations on the main steps are detailed, leaving behind
minimal gap. The author emphasizes with theory the link between
the macroscopic world (thermodynamics) and the microscopic world.
