Dissipation effects on the superconductor-insulator transition in 2-D superconductors

TL;DR

This paper investigates how dissipation influences the superconductor-insulator transition in 2D superconducting films, revealing a metallic phase emerges at low temperatures due to dissipation effects.

Contribution

It introduces a dissipation-based analysis of the superconductor-insulator transition, highlighting the emergence of a metallic phase in 2D superconductors.

Findings

Dissipation coupling becomes relevant at low temperatures.

A metallic phase appears between superconducting and insulating states.

Dissipation effects can stabilize metallic behavior in 2D superconductors.

Abstract

Results on the superconductor to insulator transition in two-dimensional films are analyzed in terms of coupling of the system to a dissipative bath. Upon lowering the temperature the parameter that controls this coupling becomes relevant and a wide range of metallic phase is recovered.
