Identifying -wave pairing symmetry in single-layer FeSe from topologically trivial edge states
Zhongxu Wei, Shengshan Qin, Cui Ding +4
Determining the pairing symmetry of single-layer FeSe on SrTiO is the key to understanding the enhanced pairing mechanism; furthermore, it guides exploring new superconductors…
Emergence of superconducting dome in insulating ZrNx films via nitrogen manipulation
Fucong Chen, Xinbo Bai, Yuxin Wang +19
Reproducing the electronic phase diagram of strongly correlated high-transition-temperature (high-Tc) superconductors in materials other than Cu-, Fe-, and Ni-based compounds has b…
Enhancement of Superconductivity Linked with Linear-in-Temperature/Field Resistivity in Ion-Gated FeSe Films
Xingyu Jiang, Mingyang Qin, Xinjian Wei +25
Iron selenide (FeSe) - the structurally simplest iron-based superconductor, has attracted tremendous interest in the past years. While the transition temperature (Tc) of bulk FeSe…
Ionic liquid gating induced two superconductor-insulator phase transitions in spinel oxide LiTiO
Zhongxu Wei, Qian Li, Ben-Chao Gong +13
The associations between emergent physical phenomena (e.g., superconductivity) and orbital, charge, and spin degrees of freedom of electrons are intriguing in transition metal…
Combinatorial Laser Molecular Beam Epitaxy System Integrated with Specialized Low-temperature Scanning Tunneling Microscopy
Ge He, Zhongxu Wei, Zhongpei Feng +6
We present a newly developed facility, comprised of a combinatorial laser molecular beam epitaxy system and an in-situ scanning tunneling microscopy (STM). This facility aims at ac…
Giant enhancement of critical current density at high field in superconducting (Li,Fe)OHFeSe films by Mn doping
Dong Li, Jie Yuan, Peipei Shen +14
Critical current density (Jc) is one of the major limiting factors for high field applications of iron-based superconductors. Here, we report that Mn-ions are successfully incorpor…

High-field electrical transport and point-contact tunneling spectroscopy were used to investigate superconducting properties of the unique spinel oxide, LiTiO films wit…
Semigroup approach to the sign problem in quantum Monte Carlo simulations
Zhong-Chao Wei
We propose a framework based on the concept of the semigroup to understand the fermion sign problem. By using properties of contraction semigroups, we obtain sufficient conditions…
Phase transition of the q-state clock model: duality and tensor renormalization
Jing Chen, Hai-Jun Liao, Hai-Dong Xie +6
We investigate the critical behavior and the duality property of the ferromagnetic -state clock model on the square lattice based on the tensor-network formalism. From the entan…
Self-consistent spin-wave analysis of the 1/3 magnetization plateau in the kagome antiferromagnet
Zhong-Chao Wei, Hai-Jun Liao, Jing Chen +6
We propose a modified spin-wave theory to study the 1/3 magnetization plateau of the antiferromagnetic Heisenberg model on the kagome lattice. By the self-consistent inclusion of q…
Anisotropic electron-phonon coupling in the spinel oxide superconductor
Ge He, Yanli Jia, Xingyuan Hou +12
Among hundreds of spinel oxides, LiTi2O4 (LTO) is the only one that exhibits superconductivity (Tc ~13 K). Although the general electron-phonon coupling is still the main mechanism…
Ground State Degeneracy of Interacting Spinless Fermions
Zhong-Chao Wei, Xing-Jie Han, Zhi-Yuan Xie +1
We propose an eigen-operator scheme to study the lattice model of interacting spinless fermions at half filling and show that this model possesses a hidden form of reflection posit…
Translation invariant tensor product states in a finite lattice system
J. W. Cai, Q. N. Chen, H. H. Zhao +4
We show that the matrix (or more generally tensor) product states in a finite translation invariant system can be accurately constructed from the same set of local matrices (or ten…
