[PDF] Semiclassical physics Matthias Brack, Rajat Bhaduri, Rajat K. Bhaduri

Semiclassical Physics emphasizes the close connection between the shorter classical periodic orbits, and the partially resolved quantum fluctuations in the level density and response of an autonomous finite quantum system. Particular care is taken to present a detailed derivation of Gutzwiller’s trace formula, and its extensions to continuous symmetries, zeta function techniques, and diffractive orbits.
