Book review of Z. Haba, Feynman Integral and Random Dynamics in Quantum Physics
Alec Maassen van den Brink
Abstract
The book deals with a stochastic formulation of path integration in real time, by rotating thespace variables over exp(i pi/4). Preliminary chapters deal with quantum and classical mechanics, probability theory and stochastic calculus, and the conventional approach to path integration through the Trotter product formula. Subsequently, the stochastic formulation in complex space is established, and applied to semi-classical expansions, nonlinear oscillations, quantum dynamics on analytic manifolds, dissipative systems (i.e., those which are open in that they interact with an environment), tunneling, field theory, and computer simulations.
