Introduction

This textbook offers an introduction to statistical mechanics, special relativity, and quantum physics, developed from lecture notes for the "Quantum Physics" course at the University of Padua. Beginning with a brief review of classical statistical mechanics in the first chapter, the book explores special and general relativity in the second chapter.

Historical Analysis of Light Quantization

The third chapter delves into the historical analysis of light quantization, while the fourth chapter discusses Niels Bohr's quantization of energy levels and electromagnetic transitions.

Schrödinger Equation

The Schrödinger equation is investigated in the fifth chapter.

Applications of Quantum Mechanics

Chapter Six covers applications of quantum mechanics, including the quantum particle in a box, quantum particle in harmonic potential, quantum tunneling, stationary perturbation theory, and time-dependent perturbation theory.

Basic Axioms of Quantum Mechanics

Chapter Seven outlines the basic axioms of quantum mechanics.

Quantum Atomic Physics

Chapter Eight focuses on quantum atomic physics, emphasizing electron spin and utilizing the Dirac equation for theoretical justification.

Quantum Mechanics Principles for Identical Particles

The ninth chapter explains quantum mechanics principles for identical particles at zero temperature, while Chapter Ten extends the discussion to quantum particles at finite temperature.

Quantum Information and Path Integral

Chapter Eleven provides insights into quantum information and entanglement, and the twelfth chapter explains the path integral approach to quantum mechanics.
