Understanding interaction-driven transport in flux lattices with evolution-path symmetry
Jian-Song Pan, Xiaofan Zhou, Wei Yi
The destruction of Aharonov-Bohm (AB) caging by interaction and the emergence of interaction-induced chiral currents in flux lattices are two paradigmatic examples of interaction-d…
Spin-imbalanced fermion on a dynamic lattice
Jie Liu, Xiaofan Zhou, Suotang Jia
We investigate the magnetic order of a one-dimensional spin-1/2 fermion dynamical lattice, where itinerant fermions are coupled to bond-centered localized spins via an Ising-like s…
Topological phases protected by projective space-time inversion symmetry in alkaline-earth-metal-like atoms
Xiaofan Zhou, Suotang Jia, Jian-Song Pan
An important aspect in categorizing topological phases is whether the system is spinless or spinful, given that these classes exhibit distinct symmetry algebras, leading to dispara…
Interaction-induced chiral-transport inversion
Li Pan, Qian Liang, Chang-An Yang +6
We investigate the chiral dynamics of locally interacting bosons in a two-leg flux ladder, where on-site interactions, despite being fully isotropic, counterintuitively reverse the…
Bosonic Peierls state emerging from the one-dimensional Ising-Kondo interaction
Jingtao Fan, Xiaofan Zhou, Suotang Jia
As an important effect induced by the particle-lattice interaction, the Peierls transition, a hot topic in condensed matter physics, is usually believed to occur in the one-dimensi…
Interaction-induced phase transitions at topological quantum criticality of an extended Su-Schrieffer-Heeger model
Xiaofan Zhou, Suotang Jia, Jian-Song Pan
Topological phases at quantum criticality attract much attention recently. Here we numerically study the interaction-induced phase transitions at around the topological quantum cri…
