Chiral fermion reversal in chiral crystals
Hang Li, Sheng Xu, Zhi-Cheng Rao +13
In materials chiral fermions such as Weyl fermions are characterized by nonzero chiral charges, which are singular points of Berry curvature in momentum space. Recently, new types…
Anomalous doping evolution of nodal dispersion revealed by in-situ ARPES on continuously doped cuprates
Yigui Zhong, Jianyu Guan, Jin Zhao +9
We study the systematic doping evolution of nodal dispersions by in-situ angle-resolved photoemission spectroscopy on the continuously doped surface of a high-temperature supercond…
Experimental evidence of anomalously large superconducting gap on topological surface state of - film
J. -Y. Guan, L. -Y. Kong, L. -Q. Zhou +12
Connate topological superconductor (TSC) combines topological surface states with nodeless superconductivity in a single material, achieving effective -wave pairing without inte…
New classes of chiral topological nodes with non-contractible surface Fermi arcs in CoSi
Z. -C. Rao, H. Li, T. -T. Zhang +18
In condensed matter systems, chiral topological nodes are robust band crossing points in momentum space that carry nonzero Chern numbers. The chirality is manifested by the presenc…
Observation of half-integer level shift of vortex bound states in an iron-based superconductor
Lingyuan Kong, Shiyu Zhu, Michał Papaj +14
Vortices in topological superconductors host Majorana zero modes (MZMs), which are proposed to be building blocks of fault-tolerant topological quantum computers. Recently, a new s…
