Correlation Effects in a Simplified Bilayer Two-Orbital Hubbard Model at Half Filling
Jian-Jian Yang, Dao-Xin Yao, Han-Qing Wu
Motivated by the discovery of high-temperature superconductivity in bilayer nickelate LaNiO under pressure, we investigate the ground-state phase diagram and correlatio…
Quantum phase transitions and composite excitations of antiferromagnetic spin trimer chains in a magnetic field
Jun-Qing Cheng, Zhi-Yao Ning, Han-Qing Wu +1
Motivated by recent advancements in theoretical and experimental studies of the high-energy excitations on an antiferromagnetic trimer chain, we numerically investigate the quantum…
Magnon, doublon and quarton excitations in 2D S=1/2 trimerized Heisenberg models
Yue-Yue Chang, Jun-Qing Cheng, Hui Shao +2
We investigate the magnetic excitations of the trimerized Heisenberg models with intra-trimer interaction and inter-trimer interaction on four different two-dimensional…
Phase diagram and critical behavior of Hubbard model on the square-hexagon-octagon lattice
Xinwei Jia, Dao-Xin Yao, Han-Qing Wu
Employing the projective formalism of determinant quantum Monte Carlo (DQMC) simulations, we meticulously explore the ground-state phase diagram and critical behavior of the half-f…
