Specific heat study of Fulde–Ferrell–Larkin–Ovchinnikov superconducting states in multibands materials - Iron-based Systems

Abstract

The Fulde-Ferrell-Larkin-Ovchinnikov phase is the superconducting state for which the Cooper pairs have non-zero total momentum. From the time of conception of this phase, many groups have been searching for a realization of the state. Here we describe a proposal of experimental verification of this state in the case of multibands systems, by carrying out the specific-heat measurement.
