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…
Site-selective doublon-holon dynamics in a pumped one-dimensional Hubbard superlattice with staggered Coulomb interactions
Zhenyu Cheng, Ying Li, Hantao Lu +4
Doublon-holon dynamics is investigated in a pumped one-dimensional Hubbard model with a staggered on?site Coulomb interaction at half-filling. When the system parameters are set to…
Role of vertex corrections in the spin-fluctuation mediated pairing mechanism
Z. B. Huang, W. Hanke, E. Arrigoni
We study numerically and partly diagrammatically the renormalization of the electron-spin interaction or vertex in a two-dimensional one-band Hubbard model with spin-fluctuation mo…
