Disorder-free localization in an interacting two-dimensional lattice gauge theory
P. Karpov, R. Verdel, Y. -P. Huang +2
Disorder-free localization has been recently introduced as a mechanism for ergodicity breaking in low-dimensional homogeneous lattice gauge theories caused by local constraints imp…
Slave-rotor theory on magic-angle twisted bilayer graphene
Shin-Ming Huang, Yi-Ping Huang, Ting-Kuo Lee
We investigate the correlated electrons in the magic-angle twisted bilayer graphene by using the slave-rotor mean-field theory. Owing to the extended figure of Wannier orbitals, we…
Dynamical quantum phase transitions in quantum link models
Yi-Ping Huang, Debasish Banerjee, Markus Heyl
Quantum link models are extensions of Wilson-type lattice gauge theories which realize exact gauge invariance with finite-dimensional Hilbert spaces. Quantum link models not only r…
Tunneling-induced restoration of classical degeneracy in quantum kagome ice
Kai-Hsin Wu, Yi-Ping Huang, Ying-Jer Kao
Quantum effect is expected to dictate the behaviour of physical systems at low temperature. For quantum magnets with geometrical frustration, quantum fluctuation usually lifts the…
Building crystalline topological phases from lower-dimensional states
Sheng-Jie Huang, Hao Song, Yi-Ping Huang +1
We study the classification of symmetry protected topological (SPT) phases with crystalline symmetry (cSPT phases). Focusing on bosonic cSPT phases in two and three dimensions, we…
