Stripes in high temperature superconductors dilate under the influence of an external electric field

TL;DR

This paper investigates how external electric and magnetic fields affect stripe structures in high-temperature superconductors, revealing that electric fields cause stripe dilation while magnetic fields suppress stripe formation.

Contribution

It introduces a modified time-dependent Ginzburg-Landau model to analyze electric field effects on stripes, providing new insights into field-induced stripe dynamics in superconductors.

Findings

Electric fields cause hole-like stripes to widen and electron-like stripes to narrow.

Magnetic fields suppress stripe formation.

Results align with experimental STM observations.

Abstract

In this work we study the influence of an electric field on stripes and compare our results with experimental findings from scanning tunneling microscope measurements. By introducing a negative-bias electric field into a time-dependent Ginzburg-Landau equation with stable stripe solutions, we show that hole(electron)-like stripes widen (narrow) compared to the field free case. When a magnetic field is introduced instead, stripe formation is found to be suppressed.
