Phase transitions in anisotropic graphene

TL;DR

This paper investigates how anisotropy influences phase transitions in graphene using a strongly coupled effective field theory and Schwinger-Dyson equations, revealing that anisotropy lowers the critical coupling needed for phase transition.

Contribution

It introduces a novel analysis of anisotropic effects on graphene's phase transitions through non-perturbative Schwinger-Dyson equations.

Findings

Anisotropy reduces the critical coupling for phase transition.

The study employs a strongly coupled effective field theory.

Schwinger-Dyson equations are used to analyze the system.

Abstract

We study the effect of anisotropy on phase transitions in graphene. We work with an low energy effective field theory which is strongly coupled, and solve a coupled set of Schwinger-Dyson equations. We show that the effect of anisotropy is to reduce the critical coupling.
