Revealing a charge-density-wave gap in the predicted weak topological insulator HoSbTe
J. L. Liu, R. Liu, M. Yang +7
HoSbTe was predicted to be a weak topological insulator, whose spin-orbit coupling (SOC) gaps are reported to be as large as hundreds of meV. Utilizing infrared spectroscopy, we fi…
Thermodynamic and Dynamical Signatures of a Quantum Spin-Hall Insulator to Superconductor Transition
Martin Hohenadler, Yuhai Liu, Toshihiro Sato +3
Thermodynamic and dynamical properties of a model of Dirac fermions with a deconfined quantum critical point (DQCP) separating an interaction-generated quantum spin-Hall insulator…
Special Transition and Extraordinary Phase on the Surface of a Two-Dimensional Quantum Heisenberg Antiferromagnet
Chengxiang Ding, Wenjing Zhu, Wenan Guo +1
Continuous phase transitions exhibit richer critical phenomena on the surface than in the bulk, because distinct surface universality classes can be realized at the same bulk criti…
Metal-Insulator transition in strained Graphene: A quantum Monte carlo study
