超导液晶的相变

Phase transitions in superconductor liquid crystals

Daniel G. Barci, Eduardo Fradkin

摘要:

本文研究了二维超导液晶相的相变性质,分析了最近提出的对密度波(PDW)与双$4e$超导体($4e$ SC)之间的竞争.向列波动增强了$4e$ SC并抑制了PDW相位。在没有晶格效应的情况下,PDW态只存在于T=0处,低温相是具有短程PDW有序的双链$4e$ SC。给出了$4e$ SC的几何描述。

英文摘要:

We study properties of phase transitions of 2D 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.
