Quench dynamics in the one-dimensional mass-imbalanced ionic Hubbard model
Zhuotao Xie, Ming Zhao, Hantao Lu +4
Using the time-dependent Lanczos method, we study the non-equilibrium dynamics of the one-dimensional ionic-mass imbalanced Hubbard chain driven by a quantum quench of the on-site…

Phase transitions in the Haldane-Hubbard model with ionic potentials
Hao Yuan, Yangbin Guo, Ruifeng Lu +2
By employing the exact-diagonalization method, we revisit the ground-state phase diagram of the Haldane-Hubbard model on the honeycomb lattice with staggered sublattice potentials.…
