Emergent gauge flux and spin ordering in magnetized triangular spin liquids: Applications to Hofstadter-Hubbard model
Jiahao Yang, Hao Tian, Si-Yu Pan +1
Motivated by recent progress in moiré superlattices and spin-1/2 triangular-lattice antiferromagnets, we study how orbital magnetic flux and Zeeman coupling compete or cooperate in…

Gauge flux generations of weakly magnetized Dirac spin liquid in a kagomé lattice
Si-Yu Pan, Jiahao Yang, Gang v. Chen
Inspired by the recent progress on the Dirac spin liquid and the kagomé lattice antiferromagnets, we revisit the U(1) Dirac spin liquid on the kagomé lattice and consider the res…

Multipolar ferroelectricity in the Mott regime
Pengwei Zhao, Jiahao Yang, Gang v. Chen
Ferroelectricity has been one major focus in modern fundamental research and technological application. We consider the physical origin of improper ferroelectricity in Mott insulat…
