Log-periodic quantum magneto-oscillations and discrete scale invariance in topological material HfTe5
Huichao Wang, Yanzhao Liu, Yongjie Liu +13
Discrete scale invariance (DSI) is a phenomenon featuring intriguing log-periodicity which can be rarely observed in quantum systems. Here we report the log-periodic quantum oscill…
Anomalous quantum Griffiths singularity in ultrathin crystalline lead films
Yi Liu, Ziqiao Wang, Pujia Shan +9
We study the magnetic field induced superconductor-metal transition (SMT) in ultrathin crystalline Pb films. By performing ultralow temperature transport measurement, the divergent…
Effects of random domains on the zero Hall plateau in quantum anomalous Hall effect
Chui-Zhen Chen, Haiwen Liu, X. C. Xie
Recently, a zero Hall conductance plateau with random domains is experimentally observed in quantum anomalous Hall (QAH) effect. We study the effects of random domains on the zero…
Discrete Scale Invariance in Topological Semimetals
Haiwen Liu, Hua Jiang, Ziqiang Wang +2
The discovery of Weyl and Dirac semimetals has produced a number of dramatic physical effects, including the chiral anomaly and topological Fermi arc surface states. We point out t…
Charge transport properties of the Majorana zero mode induced noncollinear spin selective Andreev reflection
Xin Shang, Haiwen Liu, Ke Xia
We study the charge transport of the spin-selective Andreev reflection(SSAR) effect between a spin polarized scanning tunneling microscope(STM) tip and a Majorana zero mode(MZM). C…
Manipulation and Characterization of the Valley Polarized Topological Kink States in Graphene Based Interferometers
Shu-guang Cheng, Haiwen Liu, Hua Jiang +2
Valley polarized topological kink states, existing broadly in the domain wall of hexagonal lattices systems, are identified in experiments, unfortunately, only very limited physica…
