Frequency renormalization and its effects in nonlinear phononics with -type coupling
Yijie Zeng
A two-phonon system with lowest-order coupling of form is studied by perturbation method, and analytic results for both phonon displacements and frequencies are obtai…
An \textit{ab initio} study of magnetic structure transitions of FePS under high pressure
Yijie Zeng, Dao-Xin Yao, Man-Rong Li
Recent experimental work shows that FePS undergoes phase transitions from () to () at GPa and then to metallic …
Superconductivity in CuIr2-xAlxTe4 telluride chalcogenides
Dong Yan, Lingyong Zeng, Yijie Zeng +6
The relationship between charge-density-wave (CDW) and superconductivity (SC), two vital physical phases in condensed matter physics, has always been the focus of scientists' resea…
Defect Engineered Room-Temperature Ferromagnetism in Quasi-Two-Dimensional Nitrided CoTa2O6
Yalin Ma, Shuang Zhao, Xiao Zhou +11
Thermal ammonolysis of quasi-two-dimensional (quasi-2D) CoTa2O6 yields the O2-/N3- and anionic vacancy ordered Co2+Ta5+2O6-xN2x/3x/3 (x 0.15) that exhibits a transitio…
Charge density wave and superconductivity in the family of telluride chalcogenides Zn1-xCuxIr2-yN(N = Al, Ti, Rh)yTe4
Dong Yan, Yijie Zeng, Yishi Lin +8
The interplay between superconductivity and charge density wave (CDW)/metal-to-insulator transition (MIT) has long been interested and studied in condensed matter physics. Here we…
CuIr2Te4: A Quasi-Two-Dimensional Ternary Telluride Chalcogenide Superconductor
Dong Yan, Yijie Zeng, Guohua Wang +9
Here we report the first observation of superconductivity in the AB2X4-type ternary telluride CuIr2Te4, which is synthesized by a solid-state method in an evacuated quartz jacket.…
NbSeTe -A New Layered Transition Metal Dichalcogenide Superconductor
Dong Yan, Shu Wang, Yishi Lin +8
Transition metal dichalcogenides (TMDCs) usually exhibit layered polytypic structures due to the weak interlayer coupling. 2H-NbSe2 is one of the most widely studied in the pristin…
Topological phase transition induced by magnetic proximity effect in two dimensions
Yijie Zeng, Luyang Wang, Song Li +3
We study the magnetic proximity effect on a two-dimensional topological insulator in a CrI/SnI/CrI trilayer structure. From first-principles calculations, the BiI-t…
-Hourglass Weyl fermions in nonsymmorphic materials
Yijie Zeng, Luyang Wang, Dao-Xin Yao
Hourglass-like band structures protected by nonsymmorphic space group symmetries can appear along high-symmetry lines or in high-symmetry surfaces in the Brillouin zone. In this wo…
