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…
Control of localized states of itinerant electrons and their magnetic interactions
Yaxin Sun, I. S. Lobanov, Jiahao Su +2
Controlling the magnetic properties of nanosystems by an electric field offers a number of advantages for spintronics applications. Using the noncollinear Alexander-Anderson model,…
Altermagnetic-doping interplay as a route to enhanced d-wave pairing in the Hubbard model
Ji Liu, Jianyu Li, Peng Zhang +2
Altermagnets - collinear, zero-net-moment magnets with momentum-odd spin splitting protected by crystalline symmetries - offer a tunable route to suppress long-range antiferromagne…
Oriented Triplet -Wave Pairing from Fermi surface Anisotropy and Nonlocal Attraction
Shuning Tan, Ji Liu, Minghuan Zeng +3
Using constrained-path quantum Monte Carlo, we map the ground-state phase diagram versus the nearest-neighbor (NN) attraction and spin-dependent hopping anisotropy for the…
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…
Pairing phase diagram for electron-doped cuprates in the square-lattice Hubbard model
Zhangkai Cao, Shuning Tan, Ji Liu +4
Motivated by significant discrepancies between experimental observations of electron-doped cuprates and numerical results of the Hubbard model, we investigate the role of nearest-n…
