Strongly-coupled Josephson junction array for simulation of frustrated one-dimensional spin models
Liang-Hui Du, Xingxiang Zhou, Yong-Jian Han +2
We study the capacitance-coupled Josephson junction array beyond the small-coupling limit. We find that, when the scale of the system is large, its Hamiltonian can be obtained with…
Robust topological insulator surface conduction under strong surface disorder
Quansheng Wu, Liang Du, Vincent E. Sacksteder
Topological insulators are characterized by specially protected conduction on their outer boundaries. We show that the protected edge conduction exhibited by 2-D topological insula…
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…
