Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Weicheng Ye, Meng Guo, Yin-Chen He +2
Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on the emergibility problem, i.e. whether a quantum phase or phase transition can emerge in a many-body system. We d…
Edge physics at the deconfined transition between a quantum spin Hall insulator and a superconductor
Ruochen Ma, Liujun Zou, Chong Wang
We study the edge physics of the deconfined quantum phase transition (DQCP) between a spontaneous quantum spin Hall (QSH) insulator and a spin-singlet superconductor (SC). Although…
Ultraviolet-Infrared Mixing in Marginal Fermi Liquids
Weicheng Ye, Sung-Sik Lee, Liujun Zou
When Fermi surfaces (FSs) are subject to long-range interactions that are marginal in the renormalization-group sense, Landau Fermi liquids are destroyed, but only barely. With the…
Reaction-diffusion dynamics in a Fibonacci chain: Interplay between classical and quantum behavior
Cheng-Ju Lin, Liujun Zou
We study the reaction-diffusion dynamics of Fibonacci anyons in a one dimensional lattice. Due to their non-Abelian nature, besides the position degree of freedom (DOF), these anyo…
Stiefel Liquids: Possible Non-Lagrangian Quantum Criticality from Intertwined Orders
Liujun Zou, Yin-Chen He, Chong Wang
We propose a new type of quantum liquids, dubbed Stiefel liquids, based on dimensional nonlinear sigma models on target space , supplemented with Wess-Zumino-Wit…
