Variational Method | Quantum Mechanics PYQs | CSIR NET Physical Science | GATE
#potentialg In this lecture, we cover the complete Perturbation Theory used in Quantum Mechanics—one of the most frequently asked topics in CSIR NET Physical Sciences and GATE Physics. We build the theory from the basics and move into advanced exam-oriented concepts. ✅ Topics Covered: We’ll cover: The concept and mathematical formalism of the Variational Principle Applications of the Variational Method in quantum systems Step-by-step PYQs (Previous Year Questions) from CSIR NET and GATE Time-Independent Perturbation Theory Non-Degenerate Perturbation Theory Degenerate Perturbation Theory Energy Corrections Wavefunction Corrections Applications & CSIR/GATE PYQs 🔹 Time-Dependent Perturbation Theory • Transition Probability • Fermi’s Golden Rule • First-Order & Second-Order Corrections • Two-State Systems • Exam-oriented derivations & tricks This lecture is highly useful for CSIR NET Physics, GATE Physics, JEST, TIFR, B.Sc. Physics, and M.Sc. Physics students preparing for Quantum Mechanics.
