Phase Transitions in Condensed Matter and Relativistic QFT

TL;DR

This paper reviews phase transition theories in condensed matter and relativistic quantum field theory, addresses recent experimental discrepancies, and proposes an alternative explanation consistent with observed data.

Contribution

It introduces a new theoretical framework that reconciles experimental results in He4 with phase transition predictions, challenging previous models.

Findings

Agreement with He3 experiments supports the unifying picture.

Recent He4 experiments deviate from predictions, prompting re-evaluation.

Proposed alternative model explains He4 experimental outcomes.

Abstract

Kibble and Zurek have provided a unifying picture for the onset of phase transitions in relativistic QFT and condensed matter systems respectively, strongly supported by agreement with condensed matter experiments in He3. The failure of a recent experiment on He4 to agree with the predictions has prompted a reappraisal of this picture. We provide an alternative picture that explains the experimental evidence.
