Orbital-Selective Mott and Antiferromagnetic Phases in Diagonally Compressed Kagome Lattice
Jiewei Ding, Ho-Kin Tang, Wing Chi Yu
We perform determinant quantum Monte Carlo simulations of the half-filled Hubbard model on a diagonally compressed kagome lattice, introducing exponential decay long-range hopping…

Crossover in the Ordered Phase in the Non-Mermin-Wagner-Hohenberg Regime of Spin Models with Long-Range Coupling
Jiewei Ding, Jiahao Su, Ho-Kin Tang +1
Continuous spin models with long-range interactions of the form , where is the distance between two spins and controls the decay of the interaction, exhibit enhan…
