Topological invariants for phase transition points of one-dimensional topological systems

Linhu Li, Chao Yang, Shu Chen

We study topological properties of phase transition points of two topologically non-trivial classes (D and DIII) in one dimension by assigning a Berry phase defined…

Strongly interacting one-dimensional quantum gas mixtures with weak p-wave interactions

Haiping Hu, Lei Pan, Shu Chen

We study one-dimensional strongly interacting quantum gas mixtures, including both the Bose-Fermi and spin-1/2 Fermi-Fermi mixtures, with weak p-wave interactions between intra-com…

Bosonic edge states in gapped honeycomb lattices

Huaiming Guo, Yuekun Niu, Shu Chen +1

By quantum Monte Carlo simulations of bosons in gapped honeycomb lattices, we show the existence of bosonic edge states. For single layer honeycomb lattice, bosonic edge states can…

Fractional Topological States in Quantum Spin Chains with Periodical Modulation

Haiping Hu, Huaiming Guo, Shu Chen

We report the findings of fractional topological states in one-dimensional periodically modulated quantum spin chains with up to third neighbor interactions. By exact numerical stu…
