Non-Majorana-origin of the half-integer conductance quantization elucidated by multi-terminal superconductor-quantum anomalous Hall insulator heterostructure
Anjana Uday, Gertjan Lippertz, Bibek Bhujel +2
Chiral one-dimensional transport can be realized in thin films of a surface-insulating ferromagnetic topological insulator called quantum anomalous Hall insulator (QAHI). When supe…

Electrostatically controlled spin polarization in Graphene-CrSBr magnetic proximity heterostructures
Boxuan Yang, Bibek Bhujel, Daniel G. Chica +4
The magnetic proximity effect can induce a spin dependent exchange shift in the band structure of graphene. This produces a magnetization and a spin polarization of the electron/ho…
