Spin-textured orbitals in altermagnetic artificial atoms
Yue Mao, Yu-Chen Zhuang, Cheng-Ming Miao +2
Artificial atoms provide a versatile platform for engineering atomic-like orbitals, yet spin generally remains a passive degree of freedom in their orbital structure. Here, we intr…
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…
Phase transitions in quantum dot-Majorana zero mode coupling systems
Yue Mao, Qing-Feng Sun
The magnetic doublet ground state (GS) of a quantum dot (QD) could be changed to a spin-singlet GS by coupling to a superconductor. In analogy, here we study the GS phase transitio…
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…
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…
Design of Josephson diode based on magnetic impurity
Yu-Fei Sun, Yue Mao, Qing-Feng Sun
We theoretically propose a mechanism to realize the superconducting diode effect (SDE): The current can generate a magnetic field, affecting the magnetic moment of magnetic impurit…
Four-terminal graphene-superconductor thermal switch controlled by the superconducting phase difference
Peng-Yi Liu, Yue Mao, Qing-Feng Sun
We propose a superconducting phase-controlled thermal switch based on a four-terminal graphene-superconductor system. By the coupling of two superconducting leads on a zigzag graph…
Tunable Atomically Wide Electrostatic Barriers Embedded in a Graphene WSe2 Heterostructure
Hui-Ying Ren, Yue Mao, Ya-Ning Ren +2
Inducing and controlling electrostatic barriers in two-dimensional (2D) quantum materials has shown extraordinary promise to enable control of charge carriers, and is key for the r…
Mode mixing induced by disorder in graphene PNP junction in a magnetic field
Ning Dai, Qing-Feng Sun
We study the electron transport through the graphene PNP junction under a magnetic field and show that modes mixing plays an essential role. By using the non-equilibrium Green's fu…
Theory of Nonequilibrium Coherent Transport through an Interacting Mesoscopic Region Weakly Coupled to Electrodes
Yu Zhu, Tsung-han Lin, Qing-feng Sun
We develop a theory for the nonequilibrium coherent transport through a mesoscopic region, based on the nonequilibrium Green function technique. The theory requires the weak coupli…
