Ni-based transition-metal trichalcogenide monolayer: a strongly correlated quadruple-layer graphene
Yuhao Gu, Qiang Zhang, Congcong Le +3
We investigate the electronic physics of layered Ni-based trichalcogenide NiPX (X=S, Se), a member of transition-metal trichalcogenides (TMTs) with the chemical formula, ABX$_3…
Infrared spectroscopic studies of the topological properties in CaMnSb2
Ziyang Qiu, Congcong Le, Yaomin Dai +6
We present temperature-dependent infrared spectroscopic studies of CaMnSb2, a proposed threedimensional topological material. The low plasma edge in the reflectivity spectrum and s…
Universal superconductivity phase diagram for pressurized tetradymite topological insulators
Shu Cai, S. K. Kushwaha, Jing Guo +13
We show that two different superconducting phases exist at high pressures in the optimized tetradymite topological insulators Bi2Te2Se (BTS) and Bi1.1Sb0.9Te2S (BSTS). The supercon…
Route to chaos in a coupled microresonator system with gain and loss
Krzysztof Zegadlo, Nguyen Viet Hung, Vladimir V. Konotop +2
We consider chaotic dynamics of a system of two coupled ring resonators with a linear gain and a nonlinear absorption. Such a structure can be implemented in various settings inclu…
Predicting Diamond-like Co-based Chalcogenides as Unconventional High Temperature Superconductors
Jiangping Hu, Yuhao Gu, Congcong Le
We predict Co-based chalcogenides with a diamond-like structure can host unconventional high temperature superconductivity (high-). The essential electronic physics in these m…
Topological Critical Materials of Ternary Compounds
Shengshan Qin, Congcong Le, Xianxin Wu +1
We review topological properties of two series of ternary compounds AMgBi (A=K, RB, Cs) and ABC with a hexagonal ZrBeSi type structure. The first series of materials AMgBi are pred…
