Journal ArticleDOI

Dongfei Wang,Lingyuan Kong,Peng Fan,Hui Chen,Shiyu Zhu,Wenyao Liu,Lu Cao,Yujie Sun,Shixuan Du,John Schneeloch,Ruidan Zhong,Genda Gu,Liang Fu,Hong Ding,Hong-Jun Gao +14 more
TL;DR: A sharp zero-bias peak inside a vortex core that does not split when moving away from the vortex center is observed, consistent with the tunneling to a nearly pure MBS, separated from nontopological bound states.

TL;DR: In this paper, the authors used a scanning tunneling microscope on the newly discovered superconducting Dirac surface state of iron-based superconductor FeTe1-xSex (x = 0.45, superconducted transition temperature Tc = 14.5 K), and clearly observed a sharp and non-split zero bias peak inside a vortex core.

Zhi-Cheng Rao,Hang Li,Tiantian Zhang,Shangjie Tian,Chenghe Li,B. B. Fu,Cen-Yao Tang,Le Wang,Zhilin Li,Zhilin Li,Wenhui Fan,Jiajun Li,Yaobo Huang,Zhehong Liu,Youwen Long,Chen Fang,Hongming Weng,Youguo Shi,Hechang Lei,Yujie Sun,Tian Qian,Hong Ding +21 more
TL;DR: Angle-resolved photoemission spectroscopy measurements in CoSi reveal the presence of unconventional chiral fermions near the Fermi level, with giant surface Ferm i arcs and one pair of well separated chiral nodes.
Journal ArticleDOI
Half-integer level shift of vortex bound states in an iron-based superconductor
Lingyuan Kong,Shiyu Zhu,Michał Papaj,Hui Chen,Lu Cao,Hiroki Isobe,Yuqing Xing,Wenyao Liu,Dongfei Wang,Peng Fan,Yujie Sun,Shixuan Du,John Schneeloch,Ruidan Zhong,Genda Gu,Liang Fu,Hong-Jun Gao,Hong Ding +17 more
TL;DR: In this paper, a detailed scanning tunnelling spectroscopy study of a FeTe0.55Se0.45 single crystal was performed and it was shown that this material hosts two distinct classes of vortex cores.
Journal ArticleDOI
New classes of chiral topological nodes with non-contractible surface Fermi arcs in CoSi
Zhi-Cheng Rao,Hai Li,Tiantian Zhang,Shangjie Tian,Chenghe Li,B. B. Fu,Cen-Yao Tang,Lin Wang,Z. L. Li,Wenhui Fan,Junjie Li,Y. Huang,Zhi Liu,Youwen Long,Chen Fang,Hongming Weng,Youguo Shi,Hechang Lei,Yujie Sun,Tian Qian,Hong Ding +20 more
TL;DR: In this paper, the spin-1 and charge-2 Dirac topological nodes were observed at the band crossing points near the Fermi level in CoSi, the projections of which on the (001) surface are connected by topologically protected surface Fermis arcs.
