Phases and criticality of the triangular lattice SU(N) Hofstadter-Hubbard model
Lu Zhang, Rongning Liu, Xue-Yang Song
We report the study of phases and transitions of SU(N) Hofstadter-Hubbard model subject to commensurate magnetic field on the triangular lattice. At filling one fermion per site, f…

Discrete Shift and Polarization from Response to Symmetry Defects in Interacting Topological Phases
Lu Zhang, Min Long, Yuxuan Zhang +2
We extend the previous study of extracting crystalline symmetry-protected topological invariants to the correlated regime. We construct the interacting Hofstadter model defined on…

Charge-4 Anyon Superconductor from Doping chiral spin liquid
Lu Zhang, Ya-Hui Zhang, Xue-Yang Song
Previous studies have shown that chiral spin liquid can emerge in the SU() Hubbard model on triangular lattice. A natural question then arises: What is the phas…
