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…
