Complex Landau levels and related transport properties in the strained zigzag graphene nanoribbons
Zhi-qiang Bao, Ju-wen Ding, Junjie Qi
The real magnetic fields (MFs) acting on the graphene can induce flat real Landau levels (LLs). As an analogy, strains in graphene can produce significant pseudo MFs, triggering th…
Reverse strain-induced snake states in graphene nanoribbons
Cheng-Yi Zuo, Junjie Qi, Tian-Lun Lu +2
Strain can tailor the band structures and properties of graphene nanoribbons (GNRs) with the well-known emergent pseudo-magnetic fields and the corresponding pseudo-Landau levels (…
Flavor Quantum Dots and Artificial Quark Model in Transition Metal Dichalcogenides
Zhi-qiang Bao, Patrick Cheung, Fan Zhang
We show that the triply degenerate Q valleys in few-layer transition metal dichalcogenides provide a unique platform for exploring the rare flavor SU(3) symmetry in quantum dot geo…
Flavor Symmetry and Ferroelectric Nematics in Transition Metal Dichalcogenides
Patrick Cheung, Zhi-qiang Bao, Fan Zhang
Recent magneto-transport experiments have provided compelling evidence for the presence of an energetically isolated threefold Q-valley degeneracy in few-layer transition metal dic…
π and 4π Josephson Effects Mediated by a Dirac Semimetal
Wenlong Yu, Wei Pan, Douglas L. Medlin +4
Cd3As2 is a three-dimensional topological Dirac semimetal with connected Fermi-arc surface states. It has been suggested that topological superconductivity can be achieved in the n…
Ginzburg-Landau-type theory of non-polarized spin superconductivity
Peng Lv, Zhi-qiang Bao, Ai-Min Guo +2
Since the concept of spin superconductor was proposed, all the related studies concentrate on spin-polarized case. Here, we generalize the study to spin-non-polarized case. The fre…
Probing strong interactions in p-type few-layer WSe by density-dependent Landau level crossing
Shuigang Xu, Liheng An, Jiangxiazi Lin +7
Atomically thin transition metal dichalcogenides (TMDCs) such as MoS and WSe are emerging as a new platform for exploring many-body effects. Coulomb interactions are marked…
Quantum Hall Charge Kondo Criticality
Zhi-qiang Bao, Fan Zhang
The long-thought charge Kondo effects have recently been experimentally realized in the quantum Hall regime. This experiment, supported by numerics, exemplifies the realization of…
Odd-integer quantum Hall states and giant spin susceptibility in p-type few-layer WSe2
Shuigang Xu, Junying Shen, Gen Long +17
We fabricate high-mobility p-type few-layer WSe2 field-effect transistors and surprisingly observe a series of quantum Hall (QH) states following an unconventional sequence predomi…
Topological Majorana Two-Channel Kondo Effect
Zhi-qiang Bao, Fan Zhang
A one-dimensional time-reversal-invariant topological superconductor hosts a Majorana Kramers pair at each end, where time-reversal symmetry acts as a supersymmetry that flips loca…
Orbital Kondo effect in a parallel double quantum dot
Zhi-qiang Bao, Ai-Min Guo, Qing-feng Sun
We construct a theoretical model to study the orbital Kondo effect in a parallel double quantum dot (DQD). Recently, pseudospin-resolved transport spectroscopy of the orbital Kondo…
Theory for electric dipole superconductivity with an application for bilayer excitons
Qing-Dong Jiang, Zhi-qiang Bao, Qing-Feng Sun +1
Exciton superfluid is a macroscopic quantum phenomenon in which large quantities of excitons undergo the Bose-Einstein condensation. Recently, exciton superfluid has been widely st…
