This paper demonstrates that one-dimensional quantum systems can exhibit spontaneous symmetry breaking at thermal equilibrium through a novel non-Hermitian construction, challenging the conventional understanding of symmetry breaking in one-dimensional systems.
在非線性二元週期系統中,自發對稱性破缺的臨界功率與布洛赫動量密切相關,隨著布洛赫動量模數的增加而降低。
비선형 이진 주기 시스템에서 Bloch 모드의 자발적 대칭 파괴 현상은 Bloch 운동량에 크게 의존하며, 운동량이 증가함에 따라 대칭 파괴 임계값이 감소합니다.
非線形バイナリ周期系における自発的対称性の破れ(SSB)は、ブロッホ運動量に大きく依存し、運動量の増加に伴いSSBの臨界パワーが低下する。
In binary periodic systems, the power threshold for spontaneous symmetry breaking (SSB) of nonlinear Bloch modes is significantly influenced by the Bloch momentum, decreasing as the momentum approaches the edge of the Brillouin zone.
