Lieb-Schultz-Mattis Theorem with Long-Range Interactions
Ruochen Ma
We prove the Lieb-Schultz-Mattis theorem in -dimensional spin systems exhibiting spin rotation and lattice translation symmetries in the presence of local interactio…

Strong-to-Weak Spontaneous Symmetry Breaking in Mixed Quantum States
Leonardo A. Lessa, Ruochen Ma, Jian-Hao Zhang +3
Symmetry in mixed quantum states can manifest in two distinct forms: strong symmetry, where each individual pure state in the quantum ensemble is symmetric with the same charge, an…

Symmetry Protected Topological Phases of Mixed States in the Doubled Space
Ruochen Ma, Alex Turzillo
The interplay of symmetry and topology in quantum many-body mixed states has recently garnered significant interest. In a phenomenon not seen in pure states, mixed states can exhib…
