Topological magnon insulator and quantized pumps from strongly-interacting bosons in optical superlattices
Feng Mei, Gang Chen, N. Goldman +2
We propose a scheme realizing topological insulators and quantized pumps for magnon excitations, based on strongly-interacting two-component ultracold atoms trapped in optical supe…
Topological quantum walks in cavity-based quantum networks
Ya Meng, Feng Mei, Gang Chen +1
We present a protocol to implement discrete-time quantum walks and simulate topological insulator phases in cavity-based quantum networks, where the single photon is the quantum wa…
Quantum spiral spin-tensor magnetism
Xiaofan Zhou, Xi-Wang Luo, Gang Chen +2
The characterization of quantum magnetism in a large spin () system naturally involves both spin-vectors and -tensors. While certain types of spin-vector (e.g., ferromagnet…
Topological pumping of a single magnon in a one-dimensional spin-dependent optical superlattice
Feng Mei, Gang Chen, Liantuan Xiao +1
Topological pumping of ultracold atomic gases has recently been demonstrated in two experiments (Nat. Phys. 12, 296; 12, 350 (2016)). Here we study the topological pumping of a sin…
Topology-dependent quantum dynamics and entanglement-dependent topological pumping in superconducting qubit chains
Feng Mei, Gang Chen, Lin Tian +2
We propose a protocol using a tunable Xmon qubit chain to construct generalized Su-Schrieffer-Heeger (SSH) models that support various topological phases. We study the time evoluti…
