Title
Phase transitions driven by quasiparticle interactions
Author
Abstract
After a survey of the solid-liquid transition, driven by phonon-phonon interactions, attention is next focussed on two phase transitions caused by electron-phonon interactions. These are (i) the Barden-Cooper-Schrieffer pure metal superconducting transition and (ii) the original Peierls instability. These have closely similar forms for the respective transition temperatures, both being related to energy gaps. Spin-phonon interactions are then discussed in relation to spin-Peierls materials. Finally, magnon-magnon interactions are treated in the context of the ferromagnetic-paramagnetic transition in the itinerant electron systems Fe, Co and Ni. Heuristic and phenomenological arguments, plus of course experiment, provide the basis for the conclusions drawn here.
