Role of nematic fluctuations in the thermal melting of pair-density-wave phases in two-dimensional superconductors

Year: 2011

Type: article

Abstract: We study properties of phase transitions of two-dimensional superconductor liquid crystal phases, and analyze the competition between the recently proposed pair density wave (PDW) and nematic $4e$ superconductor ($4e$ SC). Nematic fluctuations enhance the $4e$ SC and suppress the PDW phase. In the absence of lattice effects, the PDW state exists only at $T=0$ and the low-temperature phase is a nematic $4e$ SC with short-ranged PDW order. A geometric description of the $4e$ SC is presented.
