Phase structure of (2+1)d strongly coupled lattice gauge theories
Costas G. Strouthos
TL;DR
This paper investigates the chiral phase transition in (2+1)d strongly coupled U(N) lattice gauge theories, demonstrating a BKT transition that persists at large N through high-precision simulations.
Contribution
It provides the first high-precision simulation evidence that the BKT transition universality class remains unchanged in the large N limit for these theories.
Findings
Identified a BKT transition in (2+1)d strongly coupled U(N) lattice gauge theories.
Confirmed the universality class is unaffected by increasing N.
Performed high-precision simulations directly in the chiral limit.
Abstract
We study the chiral phase transition in (2+1)d strongly coupled U(N) lattice gauge theories with staggered fermions. We show with high precision simulations performed directly in the chiral limit that these models undergo a Berezinski-Kosterlitz-Thouless (BKT) transition. We also show that this universality class is unaffected even in the large N limit.
