Spontaneous symmetry breaking in open quantum systems: strong, weak, and strong-to-weak
D Gu, Z Wang, Z Wang - arxiv preprint arxiv:2406.19381, 2024 - arxiv.org
Depending on the coupling to the environment, symmetries of open quantum systems
manifest in two distinct forms, the strong and the weak. We study the spontaneous symmetry …
