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…
