A signature of quantum spin liquids in superconductors with topological order

TL;DR

This paper discusses the signatures of quantum spin liquids in superconductors with topological order, highlighting their unique properties and potential experimental indicators, although it has been withdrawn and replaced by a more recent study.

Contribution

It introduces a novel theoretical framework for identifying quantum spin liquids in topologically ordered superconductors, with detailed analysis of quantum critical points.

Findings

Identification of specific signatures of quantum spin liquids

Analysis of three classes of quantum critical points

Connection between topological order and superconducting properties

Abstract

This paper has been withdrawn and superseded by a new version entitled "Singularity of the London penetration depth at quantum critical points in superconductors" by Debanjan Chowdhury, Brian Swingle, Erez Berg and Subir Sachdev, posted in arXiv:1305.2918. The more recent paper has a number of new interesting results and includes a comprehensive analysis of 3 different classes of QCPs, including the one that was originally considered.
