Laser-Induced Commensurate-Incommensurate Transition of Charge Order in a Hubbard Superlattice
Hua Chai, Zhenyu Cheng, Qinxin Hu +4
We investigate the nonequilibrium dynamics of charge density waves in a pumped one-dimensional Hubbard superlattice with staggered onsite Coulomb interactions at half-filling, usin…

A new pathway to impact ionization in a photo-excited one-dimensional ionic Hubbard model
Zhenyu Cheng, Li Yang, Xiang Hu +3
Using the time-dependent Lanczos method, we study the non-equilibrium dynamics of the half-filled one-dimensional ionic Hubbard model, deep within the Mott insulating regime, under…
