Disentangling bulk and surface states in the electronic structure of PtBi(0001)
Stefanie Suzanne Brinkman, Xin Liang Tan, Anders Christian Mathisen +13
The paper studies the electronic structure of PtBi2 (0001) surfaces, using ARPES and calculations to separate bulk bands from surface states on two surface terminations.
A minimal model for the Weyl nodes and Fermi arcs of PtBi
Tobias Cristófoli, Manuel Alonso Lemos, Jorge I. Facio +1
Weyl semimetals host topologically protected Fermi arcs on their surfaces, originating from the Chern number of the bulk Weyl nodes. In trigonal PtBi, superconducting signature…
Fermiology and spin polarization of topological surface states in PtBi
Anders Christian Mathisen, Xin Liang Tan, Stefanie Suzanne Brinkman +12
Layered PtBi is a candidate for topological superconductivity arising in Fermi-arc surface states. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate tha…
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…
Non-linear anomalous Edelstein response at altermagnetic interfaces
Mattia Trama, Irene Gaiardoni, Claudio Guarcello +5
In altermagnets, time-reversal symmetry breaking spin-polarizes electronic states, while total magnetization remains zero. In addition, at altermagnetic surfaces Rashba-spin orbit…
Interplay between inversion and translation symmetries in trigonal PtBi
Santiago Palumbo, Pablo S. Cornaglia, Jorge I. Facio
The trigonal Weyl semimetal PtBi presents an intriguing superconducting phase, previously reported to be confined to its topological Fermi arcs within a certain temperature ran…
