Orbital order in a bosonic -band triangular lattice
Hua Chen, X. C. Xie
We present a detailed study of the Bose-Hubbard model in a -band triangular lattice by focusing on the evolution of orbital order across the superfluid-Mott insulator transition…
Klein bottle entropy of compactified boson conformal field theory
Wei Tang, X. C. Xie, Lei Wang +1
We extend the scope of the Klein bottle entropy, originally introduced by [Tu, Phys. Rev. Lett. 119, 261603 (2017)] in the rational conformal field theory (CFT), to the compactifie…
Universal Boundary Entropies in Conformal Field Theory: A Quantum Monte Carlo Study
Wei Tang, Lei Chen, Wei Li +3
Recently, entropy corrections on nonorientable manifolds such as the Klein bottle are proposed as a universal characterization of critical systems with an emergent conformal field…
Mott Physics and Topological Phase Transition in Correlated Dirac Fermions
Shun-Li Yu, X. C. Xie, Jian-Xin Li
We investigate the interplay between the strong correlation and the spin-orbital coupling in the Kane-Mele-Hubbard model and obtain the qualitative phase diagram via the variationa…
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…
Spin current in the Kondo lattice model
S. Q. Shen, X. C. Xie
By using the projection operator technique it is observed that the strong Hund's rule coupling and s-d interaction in transition metal elements may lead to an effective coupling be…
