Second-Harmonic Imaging of Magnetic Domains in Thin Film Hematite
Holger Mirkes, Johannes Schmuck, Katharina Müller +7
Hematite is an antiferromagnetic oxide and candidate altermagnetic insulator whose Néel order reorients from an easy-axis to an easy-plane phase at the Morin transition. Interpreti…
On the origin of energy gaps in quasicrystalline potentials
Emmanuel Gottlob, David Gröters, Ulrich Schneider
Quasicrystals, structures that are ordered yet aperiodic, defy conventional band theory, confining most studies to finite-size real-space numerics. We overcome this limitation with…
Perspective on Moreau-Yosida Regularization in Density-Functional Theory

Charge, heat, and spin transport phenomena in metallic conductors
Nynke Vlietstra, Sebastian T. B. Goennenwein, Rudolf Gross +1
In solid state materials, gradients of the electro-chemical potential, the temperature, or the spin-chemical potential drive the flow of charge, heat, and spin angular momentum, re…
Interplay of energy and charge transfer in WSe2/CrSBr heterostructures
