Krylov complexity, mode-resolved complexity and entanglement entropy across phase transitions in the non-Hermitian extended Su-Schrieffer-Heeger model
Ling-Feng Zhang, Wing Chi Yu
We investigate phase transitions in the extended Su-Schrieffer-Heeger (SSH) model with next-nearest-neighbor hoppings and an imaginary staggered chemical potential. In the presence…
Orbital-Selective Mott and Antiferromagnetic Phases in Diagonally Compressed Kagome Lattice
Jiewei Ding, Ho-Kin Tang, Wing Chi Yu
We perform determinant quantum Monte Carlo simulations of the half-filled Hubbard model on a diagonally compressed kagome lattice, introducing exponential decay long-range hopping…
Order parameters and ground-state phase diagram of the interacting topological Su-Schrieffer-Heeger model with extended-range hoppings
Tsz Hin Hui, Pedro D. Sacramento, Wing Chi Yu
Topological insulators have attracted numerous attentions recent years, where the Su-Schrieffer-Heeger (SSH) model is one of the most studied models. While the interacting version…
Beyond Topological Invariants: Order Parameters from Dominant Fock-state Patterns
Tsz Hin Hui, Xiaodan Xia, Pedro D. Sacramento +1
We introduce a general scheme for constructing order parameters (OPs) by extracting generic patterns from the dominant Fock states of many-body ground states. While topological pha…
Evolution of magnetic correlation in doped Hubbard model with altermagnetic spin splitting
Yinlong Li, Rana Imran Mushtaq, Ji Liu +4
The evolution of magnetic correlation in strongly correlated electron systems with altermagentic spin splitting remains largely unexplored. Here we investigate how spin splitting g…
