二维热涨落超导体中的竞争序

Competing orders in thermally fluctuating superconductors in two dimensions

Subir Sachdev, Eugene Demler

摘要:

我们扩展最近的低温分析竞争订单的铜氧化物超导体的赝能隙制度,所有的订单波动。一个通用的连续极限的经典Ginzburg-Landau泛函的超导秩序的波动的特征:这描述了交叉从高斯波动在高温下的涡旋束缚物理附近的全局相位相干的发病。这些波动引起了其他订单的相关性,特别是在不同的实现收费秩序的附属修正。扫描隧道光谱和中子散射实验的影响注意到:可能有一个制度的温度附近的超导性的电荷顺序是随着温度的升高而增强。

英文摘要:

We extend recent low temperature analyses of competing orders in the cuprate superconductors to the pseudogap regime where all orders are fluctuating. A universal continuum limit of a classical Ginzburg-Landau functional is used to characterize fluctuations of the superconducting order: this describes the crossover from Gaussian fluctuations at high temperatures to the vortex-binding physics near the onset of global phase coherence. These fluctuations induce affiliated corrections in the correlations of other orders, and in particular, in the different realizations of charge order. Implications for scanning tunnelling spectroscopy and neutron scattering experiments are noted: there may be a regime of temperatures near the onset of superconductivity where the charge order is enhanced with increasing temperatures.
