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…
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…
Single particle tunneling spectroscopy and superconducting gaps in layered iron based superconductor KCaFeAsF
Wen Duan, Kailun Chen, Wenshan Hong +5
We perform scanning tunneling microscopy/spectroscopy study on the layered iron based superconductor KCaFeAsF with a critical temperature of about 33.5 K. Two types…
Observation and characterization of the zero energy conductance peak in the vortex core state of FeTeSe
Xiaoyu Chen, Mingyang Chen, Wen Duan +3
The search for the Majorana fermions in condensed matter physics has attracted much attention, partially because they may be used for the fault-tolerant quantum computation. It has…
Multiband superconductivity and possible nodal gap in RbCrAs revealed by Andreev reflection and single-particle tunneling measurements
Zhixin Liu, Mingyang Chen, Ying Xiang +7
By measuring point-contact Andreev reflection (PCAR) spectra in the newly discovered chromium-based quasi-one-dimensional superconductor RbCrAs, we find clear evidence…
Direct visualization of sign reversal s^+- superconducting gaps in FeTe0.55Se0.45
Mingyang Chen, Qingkun Tang, Xiaoyu Chen +7
In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi su…
Discrete energy levels of Caroli-de Gennes-Martricon states in quantum limit due to small Fermi energy in FeTeSe
Mingyang Chen, Xiaoyu Chen, Huan Yang +4
Caroli-de Gennes-Martricon (CdGM) states were predicted in 1964 as low energy excitations within vortex cores of type-II superconductors. In the quantum limit, namely $T/T_\mathrm{…
