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…
Two-Dimensional Photogalvanic Spin-Battery
Yiqun Xie, Mingyan Chen, Zewen Wu +4
Pure spin-current is of central importance in spintronics. Here we propose a two-dimensional (2D) spin-battery system that delivers pure spin-current without an accompanying charge…
