Current-induced re-entrant superconductivity and extreme nonreciprocal superconducting diode effect in valley-polarized systems
Yu-Chen Zhuang, Qing-Feng Sun
The superconducting diode effect (SDE) refers to the nonreciprocity of superconducting critical currents. Generally, the SDE has a positive and a negative critical currents jc+- co…
Tunneling Magnetoresistance Effect in Altermagnets
Yu-Fei Sun, Yue Mao, Yu-Chen Zhuang +1
As an unconventional magnet, altermagnetism attracts great interest in condensed matter physics and applies a new research platform for the spintronics. Since the tunneling magneto…
Atomic collapse of high-order singular potentials in graphene
Yu-Chen Zhuang, Yue Mao, Qing-Feng Sun
Artificial atoms in graphene hosting a series of quasi-bound states can serve as an excellent platform to explore atomic collapse and become a basis to design novel graphene nanode…
Anomalous photon-assisted tunneling in periodically driven Majorana nanowires and BCS Charge Measurement
Yuchen Zhuang, Qing-Feng Sun
The photon-assisted tunneling of Majorana bound states in a Majorana nanowire driven by the periodic field is studied both theoretically and numerically. We find that Majorana boun…
