Significant improvement of the lower critical field in Y doped Nb: potential replacement of basic material for the radio-frequency superconducting cavity
Wei Xie, Yu-Hao Liu, Xinwei Fan +1
The research of high energy and nuclear physics requires high power accelerators, and the superconducting radio-frequency (SRF) cavity is regarded as their engine. Up to now, the w…
Electronic Correlations and Evolution of the Charge-Density Wave in the Kagome Metals VSb ( = K, Rb, Cs)
Xiaoxiang Zhou, Yongkai Li, Xinwei Fan +7
The kagome metals VSb ( = K, Rb, Cs) have attracted enormous interest as they exhibit intertwined charge-density wave (CDW) and superconductivity. The alkali-meta…
Tuning the competition between superconductivity and charge order in kagome superconductor Cs(V1-xNbx)3Sb5
Yongkai Li, Qing Li, Xinwei Fan +10
The recently discovered coexistence of superconductivity and charge density wave order in the kagome systems AV3Sb5 (A = K, Rb, Cs) has stimulated enormous interest. According to t…
Superconductivity arising from pressure induced Lifshitz transition in RbPdSe with kagome lattice
Qing Li, Yuxiang Wu, Xinwei Fan +5
According to the Bardeen-Cooper-Schrieffer (BCS) theory, superconductivity usually needs well defined Fermi surface(s) with strong electron-phonon coupling and moderate quasipartic…
Distinct Properties of Vortex Bound States Driven by Temperature
Xinwei Fan, Xiaoyu Chen, Huan Yang +1
We investigate the behavior of vortex bound states in the quantum limit by self-consistently solving the Bogoliubov-de Gennes equation. We find that the energies of the vortex boun…
Origin of the Charge Density Wave in the Kagome Metal CsVSb as Revealed by Optical Spectroscopy
Xiaoxiang Zhou, Yongkai Li, Xinwei Fan +5
We report on a detailed study of the optical properties of CsVSb at a large number of temperatures above and below the charge-density-wave (CDW) transition. Above the C…
Friedel Oscillations of Vortex Bound States Under Extreme Quantum Limit in KCa2Fe4As4F2
Xiaoyu Chen, Wen Duan, Xinwei Fan +6
We report the observation of discrete vortex bound states with the energy levels deviating from the widely believed ratio of 1:3:5 in the vortices of an iron based superconductor K…
Charge-stripe Fluctuations in NdNiO as Evidenced by Optical Spectroscopy
Jiahao Hao, Xinwei Fan, Qing Li +6
We present an investigation into the optical properties of NdNiO at different temperatures from 300 down to 5~K over a broad frequency range. The optical conducti…
Contrasting physical properties of the trilayer nickelates NdNiO and NdNiO
Qing Li, Chengping He, Xiyu Zhu +3
We report the crystal structures and physical properties of trilayer nickelates NdNiO and NdNiO. Measurements of magnetization and electrical resistivity…
Decoupling of itinerant and localized -orbital electrons in the compound ScZrCo
Jin Si, Xinwei Fan, Enyu Wang +3
By using the arc-melting method, we successfully synthesized the compound ScZrCo with the space group of -. Both the resistivity and magnetic susceptibility…
Quantum Zeno dynamics of a matter-wave bright soliton
Xin Zhang, Xinwei Fan, Chang Xu +2
The quantum measurement problem, namely how the deterministic quantum evolution leads to probabilistic measurement outcomes, remains a profound question to be answered. In the pres…
