The role of nematic fluctuations in the thermal melting of pair-density-wave phases in superconductors
ORAL
Abstract
We study properties of phase transitions of the superconductor liquid crystal phases, and analyze the competition between the recently proposed Pair Density Wave (PDW) and nematic $4e$ superconductor (4eSC). Nematic fluctuations enhance the 4eSC and suppress the PDW phase. For a system decoupled from a lattice, the PDW state exists only at $T=0$ and the low temperature phase is a nematic $4e$SC with short ranged PDW order.
