A Renormalization Group Analysis of Coupled Superconducting and Stripe Order in 1+1 Dimensions

TL;DR

This paper uses renormalization group analysis to explore phase transitions in a 1+1 dimensional effective field theory describing coupled stripe and superconducting orders, identifying four distinct phases.

Contribution

It provides a detailed RG analysis of a 1+1D model for stripe and superconductor order, revealing phase structure and transitions.

Findings

Four possible phases identified: stripe order/disorder with superconducting order/disorder.

Phase diagram elucidates the interplay between stripe and superconducting fluctuations.

Theoretical framework extends understanding of low-dimensional quantum order phenomena.

Abstract

In this paper we perform a renormalization group analysis on the 1+1 dimensional version of an effective field theory (previously proposed by Dung-Hai Lee, cond-mat/011393) describing (quantum) fluctuating stripe and superconductor orders. We find four possible phases corresponding to stripe order/disorder combined with superconducting order/disorder.
