Universality of 2d Yukawa and Gross-Neveu models

TL;DR

This paper presents evidence that 2d Yukawa and Gross-Neveu models exhibit universal behavior within a specific coupling range, especially for negative , highlighting a shared critical property.

Contribution

The study demonstrates the universality of 2d Yukawa and Gross-Neveu models in a particular coupling regime, providing new insights into their shared critical behavior.

Findings

Universal behavior observed in both models for <0

Evidence supports shared critical phenomena in the models

Results suggest potential broader applicability of universality principles

Abstract

Evidence for the same universal behavior of 2d Yukawa and Gross-Neveu models in a certain range of couplings, particularly for $\kappa<0$, is presented.
