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…
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…
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,…
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…
Variation of Bose surface by Filling in Cooper pair Bose metal
Jiahao Su, Ji Liu, Jianyu Li +3
The Cooper pair Bose metal (CPBM) is a non-superfluid quantum phase in which uncondensed fermion pairs form a "Bose surface" in momentum space. We investigate the CPBM in the two-d…

Altermagnetism, featuring momentum-dependent spin splitting without net magnetization, has attracted a growing interest for spintronics. We study a Fermi Hubbard model with alterma…
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…
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…

We conduct a comprehensive \textit{ab initio} investigation of electron-electron interactions within the pyrochlore structures of RRuO, RIrO, CaRuO$…
p-wave superconductivity induced by nearest-neighbor attraction in the square-lattice extended Hubbard model
Zhangkai Cao, Jianyu Li, Jiahao Su +2
The two-dimensional (2D) Hubbard model is widely believed to contain the key ingredients of high-temperature superconductivity in cuprate materials. Here, we report a constrained p…
dx2-y2-wave Bose Metal induced by the next-nearest-neighbor hopping t'
Zhangkai Cao, Jianyu Li, Jiahao Su +2
Superconductivity arises when electrons form Cooper pairs with phase coherence. In contrast, a lack of phase coherence in Cooper pairs can lead to an uncondensed metallic ground st…
