On a Renormalization Group Approach to Dimensional Crossover

TL;DR

This paper improves a renormalization group method for understanding how quantum antiferromagnets transition between different dimensions, confirming its accuracy against previous results.

Contribution

The paper refines a renormalization group approach for dimensional crossover, demonstrating its consistency with earlier methods in specific cases.

Findings

Method yields results identical to previous approaches in some cases

Improved approach enhances understanding of dimensional crossover

Validates the renormalization group method for quantum antiferromagnets

Abstract

A recently proposed renormalization group approach to dimensional crossover in quasi-one-dimensional quantum antiferromagnets is improved and then shown to give identical results, in some cases, to those obtained earlier.
