4. Quantum tunneling

  • For a potential barrier V0 > E, the wave decays exponentially inside the barrier but can transmit with finite probability.
  • Transmission coefficient for a rectangular barrier (height V0, width L) approximated for E < V0: T ≈ e^−2κL, where κ = √(2m(V0 − E))/ħ (approximate for thick/wide barriers).

Example (simple tunneling estimate):

  • Electron (m ≈ 9.11×10^−31 kg) with E = 1 eV approaching V0 = 10 eV barrier width L = 1 nm: κ ≈ √(2m*9 eV)/ħ → compute to estimate extremely small T.

Frequently Asked Questions (FAQ)

Q1: Is "Quantum Mechanics" by V. Devanathan good for the GATE Physics exam? A: Yes. For GATE, 60% of questions are conceptual and 40% numerical. Devanathan covers the concepts excellently. However, for numerical speed, pair it with GATE previous papers.

Q2: Can I get a free PDF of Devanathan’s book legally? A: Yes, if your institution is part of the Shodhganga or e-ShodhSindhu consortium. Otherwise, "free" usually means pirated, which we advise against.

Q3: How is this book different from Griffiths? A: Griffiths is more narrative and American-style (conversational). Devanathan is direct, formal, and step-by-step. Indian students often find Devanathan easier for exams, while Griffiths is better for conceptual intuition.

Q4: What is the latest edition? A: The second edition (published 2015) includes additional chapters on relativistic quantum mechanics and quantum computing basics. Always search for the 2nd edition PDF legally. quantum mechanics by v devanathan pdf download
