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 enhance…

Efficient sampling using Macrocanonical Monte Carlo and density of states mapping
Jiewei Ding, Jiahao Su, Ho-Kin Tang +1
In the context of Monte Carlo sampling for lattice models, the complexity of the energy landscape often leads to Markov chains being trapped in local optima, thereby increasing the…
