Spontaneous breaking of non-invertible symmetries and duality to beyond-Landau transitions
Xie Chen, Shang Liu, Da-chuan Lu +1
Spontaneous symmetry breaking is a well-understood mechanism for generating distinct phases of matter. Recently, the notion of symmetry has been broadened to include operations wit…
Generalized Landau Paradigm for quantum phases and phase transitions
Xie Chen
The Landau paradigm is a central dogma for understanding phase and phase transitions in condensed matter systems, yet for decades it has been known that a variety of quantum phases…
The Symmetry Taco: Equivalences between Gapped, Gapless, and Mixed-State SPTs
Marvin Qi, Ramanjit Sohal, Xie Chen +2
Symmetry topological field theory (SymTFT), or topological holography, offers a unifying framework for describing quantum phases of matter and phase transitions between them. While…
Sequential Circuit as Generalized Symmetry on Lattice
Nathanan Tantivasadakarn, Xinyu Liu, Xie Chen
Generalized symmetry extends the usual notion of symmetry to ones that are of higher-form, acting on subsystems, non-invertible, etc. The concept was originally defined in the fiel…
Duality via Sequential Quantum Circuit in the Topological Holography Formalism
Robijn Vanhove, Vibhu Ravindran, David T. Stephen +2
Two quantum theories which look different but are secretly describing the same low-energy physics are said to be dual to each other. When realized in the Topological Holography for…
