Principles of Statistical Physics

Summary of the Book

In "Principles of Statistical Physics," B. M. Smirnov explores the fundamental mechanisms that dictate the behaviors of large systems at equilibrium and non-equilibrium states. Divided into logically structured chapters, the book covers topics ranging from the principles of probability theory and ensemble representations to thermodynamic potentials and the quantum realm of particles. Smirnov emphasizes the critical role that statistical methods play in predicting physical phenomena, making connections to real-world applications such as phase transitions, critical phenomena, and thermodynamic feedback mechanisms.

The book starts with an introduction to probability theory and its essential role in statistical physics. This is followed by an exploration of classical systems and ensembles, such as microcanonical, canonical, and grand canonical ensembles. It then transitions into quantum principles, analyzing the statistical behaviors of Bose-Einstein condensates, Fermi-Dirac distributions, and blackbody radiation. The latter chapters delve into advanced topics like non-equilibrium statistical mechanics and the associated transport phenomena, painting a complete picture of how systems evolve over time when deviating from equilibrium.

What sets this work apart is its rigorous treatment of the subject matter while remaining accessible. Smirnov combines mathematical rigor with physical intuition, ensuring readers gain a twofold appreciation of the theoretical frameworks and their relevance to observational physics.
