Superconducting phase transitions in 2+1 dimensional quantum field theories modeling generalized polaronic interactions. Part I: Jahn-Teller inspired models

Abstract

We review the fundamentals of Jahn-Teller interactions and their field theoretical modelings and show that a 2+1 dimensional gauge theory where the gauge field couples to "flavored fermions" arises in a natural way from a two-band model describing the dynamical Jahn-Teller effect. The theory exhibits a second order phase transition to novel finite-temperature superconductivity.
