Helimagnetic Josephson diode effect
Qiang Cheng, Yu-Chen Zhuang, Qing-Feng Sun
We study the Josephson diode effect in the one-dimensional superconductor/helimagnet/superconductor junctions using the Green's function method. For the spin-singlet -wave pairi…
Orbital hybridization in graphene-based artificial atoms
Yue Mao, Hui-Ying Ren, Xiao-Feng Zhou +6
Intraatomic orbital hybridization and interatomic bond formation are the two fundamental processes when real atoms are condensed to form matter. Artificial atoms mimic real atoms b…
Thermal dissipation of the quantum spin Hall edge states in HgTe/CdTe quantum well
Jing-Yun Fang, Yu-Chen Zhuang, Ai-Min Guo +1
Quantum spin Hall effect is characterized by topologically protected helical edge states. Here we study the thermal dissipation of helical edge states by considering two types of d…
Absence of edge states at armchair edges in inhomogeneously strained graphene under a pseudomagnetic field
Jing-Yun Fang, Yu-Chen Zhuang, Qing-Feng Sun
Nonuniform strain in graphene can induce a pseudo-magnetic field (PMF) preserving time-reversal symmetry, generating pseudo-Landau levels under zero real magnetic field (MF). The d…
Wavefront dislocations in graphene systems revealed by transport measurement
Yu-Chen Zhuang, Qing-Feng Sun
The wavefront dislocation is an important and ubiquitous phenomenon in wave fields. It is closely related to the phase singularity in a wave function. Some recent studies have veri…
Phase diagrams and edge-state transitions in graphene with spin-orbit coupling and magnetic and pseudomagnetic fields
Yu-Chen Zhuang, Qing-Feng Sun
The quantum Hall (QH) effect, the quantum spin Hall (QSH) effect and the quantum valley Hall (QVH) effect are three peculiar topological insulating phases in graphene. They are cha…
Visualizing orbital angular momentum induced single wavefront dislocation in graphene
Yi-Wen Liu, Yu-Chen Zhuang, Ya-Ning Ren +5
Phase singularities are phase-indeterminate points where wave amplitudes are zero, which manifest as phase vertices or wavefront dislocations. In the realm of optical and electron…
Relativistic artificial molecules with tunable coupling and orbitals
Xiao-Feng Zhou, Yu-Chen Zhuang, Mo-Han Zhang +3
In a molecule formed by two atoms, energy difference between bonding and antibonding orbitals should depend on distance of the two atoms. However, exploring molecular orbitals of t…
Universal spin superconducting diode effect from spin-orbit coupling
Yue Mao, Qing Yan, Yu-Chen Zhuang +1
We propose a universal spin superconducting diode effect (SDE) induced by spin-orbit coupling (SOC), where the critical spin supercurrents in opposite directions are unequal. By an…
