Quantum Mechanics

Dive into the fundamental principles of quantum mechanics through a comprehensive series of lectures covering essential topics for physics students and exam preparation. Explore key concepts like the photoelectric effect, de Broglie hypothesis, Heisenberg uncertainty principle, and Schrödinger equations. Examine the failures of classical electromagnetic theory, delve into wave functions and their significance, and investigate quantum phenomena such as potential barriers and quantum tunneling. Progress through advanced topics including harmonic oscillators and linear vector spaces. Ideal for BSc and MSc physics students, as well as those preparing for NET-JRF, GATE, UPSC, and JAM exams.
