Disentangling bulk and surface states in the electronic structure of PtBi(0001)
Stefanie Suzanne Brinkman, Xin Liang Tan, Anders Christian Mathisen +13
Recent reports of surface-localized topological superconductivity in trigonal PtBi highlight the importance of understanding its surface electronic structure. We investigate th…
Generating ferro-spinetic polarizations in altermagnetic insulators
Toshihiro Sato, Mengli Hu, Ion Cosma Fulga +5
Altermagnets are a novel class of fully spin-compensated magnetic materials that nevertheless have spin-split electronic bands, offering novel perspectives for spintronics applicat…
