A book of techniques and applications, this text defines the path integral and illustrates its uses by example. It is suitable for advanced undergraduates and graduate students in physics; its sole prerequisite is a first course in quantum mechanics. For applications requiring specialized knowledge, the author supplies background material.The first part of the book develops the techniques of path integration. Topics include probability amplitudes for paths and the correspondence limit for the path integral; vector potentials; the Ito integral and gauge transformations; free particle and quadratic Lagrangians; properties of Green's functions and the Feynman-Kac formula; functional derivatives and commutation relations; Brownian motion and the Wiener integral; and perturbation theory and Feynman diagrams.
The second part, dealing with applications, covers asymptotic analysis and the calculus of variations; the WKB approximation and near caustics; the phase of the semiclassical amplitude; scattering theory; and geometrical optics. Additional topics include the polaron; path integrals for multiply connected spaces; quantum mechanics on curved spaces; relativistic propagators and black holes; applications to statistical mechanics; systems with random impurities; instantons and metastability; renormalization and scaling for critical phenomena; and the phase space path integral.

DO NOT BUY! DO NOT BUY! DO NOT BUY!
Color: Black, Color: Black
Absolute garbage chair. Only had for six month and the mesh on the seat has already come apart after using it for my home office. Chair was squaking after only three months and now I can't even sit in it cause it sags.
Can't even get my money back for this cheap garbage.

Just What I Needed for My Home Office
Color: Black
I’ve been very happy with this office chair. It was straightforward to assemble, feels sturdy, and offers excellent support for long hours at my desk.
The adjustable lumbar support, armrests, and headrest make it easy to customize for a comfortable fit, and the mesh design helps keep the chair breathable throughout the day.
Overall, this chair is comfortable, ergonomic, and a great value for a home office setup.

OK for basic Office chair
Color: Black
Positives:Comfortable chair, decent lumbar support. Negatives: no height adjustment for seat or tilt. Handles spin to sides with the slightest touch. Will try to figure out how to securehandles in place. Period good entry level office chair, should have ordered more of an upgraded chair.
