Z_N Phases in Hot Gauge Theories
Wei Chen, Mikhail Dobroliubov, and Gordon Semenoff
TL;DR
This paper discusses the limitations of realizing Z_N phases in hot gauge theories, showing they cannot be represented as physical states with Hermitian density matrices.
Contribution
It provides a theoretical argument that Z_N phases in hot gauge theories are not physically realizable as Hermitian density matrices.
Findings
Z_N phases cannot be realized as Hermitian density matrices.
Theoretical constraints on phases in hot gauge theories.
Implications for understanding gauge theory phases.
Abstract
We argue that the \zn phases of hot gauge theories cannot be realized as a real system with an Hermitean density matrix.
