Continuous symmetry analysis and systematic identification of candidate order parameters for interacting fermion models
Cheng-Hao He, Yi-Zhuang You, Xiao Yan Xu
Symmetry plays a central role in modern physics, from classifying quantum states to characterizing phases of matter through spontaneous symmetry breaking. In interacting fermionic…
Symmetric Mass Generation in a Bilayer Honeycomb Lattice with Symmetry
Cheng-Hao He, Yi-Zhuang You, Xiao Yan Xu
A central question beyond the Landau paradigm is the non-perturbative critical theory of the symmetric mass generation (SMG) transition, where strong interactions gap Dirac fermion…
Universal Dynamical Scaling of Strong-to-Weak Spontaneous Symmetry Breaking in Open Quantum Systems
Chang Shu, Kai Zhang, Zhu-Xi Luo +2
Strong-to-weak spontaneous symmetry breaking (SWSSB) defines a mixed-state phase of matter--without a pure-state counterpart--in which nonlinear observables such as the Rényi-2 co…
Fractal Subsystem Symmetries, Anomalies, Boundaries, and Effective Field Theory
Heitor Casasola, Guilherme Delfino, Yizhi You +2
This work reports an extensive study of three-dimensional topological ordered phases that, in one of the directions behave like usual topological order concerning mobility of excit…
