COLLECTIVE EXCITATIONS IN UNCONVENTIONAL SUPERCONDUCTORS AND SUPERFLUIDS
by Peter Brusov (University of Houston, USA & Rostov State University, Russia)
This is the first book that strives to give a complete and detailed description of collective modes (CMs) in unconventional superfluids and superconductors (USC). The authors describe the 2D- and 3D-models of p- and d-pairing for superfluids and superconductors constructed using the path integration technique. The CMs are calculated within these models for all superfluid phases of 3He, 3He–4He mixtures and for different unconventional superconductors under s-, p- and d-pairing. Ideas concerning the realization of mixtures of different d-wave states in high temperature superconductors are also investigated. The coverage includes superfluid 3He in aerogel, where the study of the CMs allows one to identify the superfluid phases, whose nature is as yet unknown. Experiments on collective modes in unconventional superfluids and superconductors are discussed in detail.
