Asymptotic freedom at the Berezinskii-Kosterlitz-Thouless transition without fine-tuning using a qubit regularization
Asymptotic freedom at the Berezinskii-Kosterlitz-Thouless transition without fine-tuning using a qubit regularization
We propose a two-dimensional hard-core loop-gas model as a way to regularize the asymptotically free massive continuum quantum field theory that emerges at the Berezinskii-Kosterlitz-Thouless transition. Without fine-tuning, our model can reproduce the universal step-scaling function of the classical lattice

Abstract
We propose a two-dimensional hard-core loop-gas model as a way to regularize the asymptotically free massive continuum quantum field theory that emerges at the Berezinskii-Kosterlitz-Thouless transition. Without fine-tuning, our model can reproduce the universal step-scaling function of the classical lattice
