Supermetal
Hiroki Isobe, Liang Fu
We study the effect of electron interaction in an electronic system with a high-order Van Hove singularity, where the density of states shows a power-law divergence. Owing to scale…

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…

Magic of high order van Hove singularity
Noah F. Q. Yuan, Hiroki Isobe, Liang Fu
We introduce a new type of van Hove singularity in two dimensions, where a saddle point in momentum space is changed from second-order to high-order. Correspondingly, the density o…
