Direct measurement of topological invariants in optical lattices
Lei Wang, Alexey A. Soluyanov, Matthias Troyer
We propose an experimental technique for classifying the topology of band structures realized in optical lattices, based on a generalization of topological charge pumping in quantu…
Topological phase transition in a generalized Kane-Mele-Hubbard model: A combined Quantum Monte Carlo and Green's function study
Hsiang-Hsuan Hung, Lei Wang, Zheng-Cheng Gu +1
We study a generalized Kane-Mele-Hubbard model with third-neighbor hopping, an interacting two-dimensional model with a topological phase transition as a function of third-neighbor…
Double transfer through Dirac points in a tunable honeycomb optical lattice
Thomas Uehlinger, Daniel Greif, Gregor Jotzu +4
We report on Bloch-Zener oscillations of an ultracold Fermi gas in a tunable honeycomb lattice. The quasi-momentum distribution of the atoms is measured after sequentially passing…
Quantum Spinon Oscillations
Zi Cai, Lei Wang, X. C. Xie +4
The full quantum dynamics of a spinon under external magnetic fields is investigated by using the time-evolving block decimation (TEBD) method within the microcanonical picture of…
Charge-density-wave and topological transitions in interacting Haldane model
Lei Wang, Hao Shi, Shiwei Zhang +3
Haldane model is a noninteracting model for spinless fermions showing nontrivial topological properties. Effect of the electron-electron interaction on the topological phase poses…
