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…
Dynamical recovery of SU(2) symmetry in the mass-quenched Hubbard model
Liang Du, Gregory A. Fiete
We use non-equilibrium dynamical mean-field theory with iterative perturbation theory as an impurity solver to study the recovery of symmetry in real-time following a hoppi…
Orbital-selective thermalization plateau in the mass imbalanced Hubbard model
Liang Du, Li Huang, Gregory A. Fiete
We use time-dependent non-equilibrium dynamical mean-field theory with weak-coupling auxiliary-field continuous time quantum Monte Carlo as an impurity solver to study the thermali…
Doping-driven orbital-selective Mott transition in multi-band Hubbard models with crystal field splitting
Yilin Wang, Li Huang, Liang Du +1
We have studied the doping-driven orbital-selective Mott transition in multi-band Hubbard models with equal band width in the presence of crystal field splitting. Crystal field spl…
QIST: An open source continuous-time quantum Monte Carlo impurity solver toolkit
Li Huang, Yilin Wang, Zi Yang Meng +3
Quantum impurity solvers have a broad range of applications in theoretical studies of strongly correlated electron systems. Especially, they play a key role in dynamical mean-field…
Metal-insulator transition in three-band Hubbard model with strong spin-orbit interaction
Liang Du, Li Huang, Xi Dai
Recent investigations suggest that both spin-orbit coupling and electron correlation play very crucial roles in the transition metal oxides. By using the generalized Gutzwille…
Kernel polynomial representation of imaginary-time Green's functions
Li Huang, Liang Du
Inspired by the recent proposed Legendre orthogonal polynomial representation of imaginary-time Green's functions, we develop an alternate representation for the Green's functions…
Complete phase diagram for three-band Hubbard model with orbital degeneracy lifted by crystal field splitting
Li Huang, Liang Du, Xi Dai
Motivated by the unexplored complexity of the phase diagrams for multi-orbital Hubbard models, a three-band Hubbard model at integer fillings (N=4) with orbital degeneracy lifted p…
