Anatomy of Spin--Orbit Torques in Monolayer FeGeTe and FeGaTe: Insights from atomistic and momentum-space decompositions
Gusthavo M. S. Brizolla, Stepan S. Tsirkin, Yaroslav Zhumagulov +1
We present a systematic first-principles study of the spin-orbit torques in the ferromagnetic monolayers FeGeTe (FGT) and FeGaTe (FGaT). Despite sharing the same cr…
First-Principles Wannier Representation of Proximity Effects
Yaroslav Zhumagulov, Johan Félisaz, Stepan S. Tsirkin +2
The paper introduces a first‑principles method to construct a dynamical proximity operator from density functional theory, allowing exact downfolding of heterostructure Hamiltonian…
Electronic properties and topological aspects of graphene nanohelicoids
Xiaoqian Liu, Arsen Herasymchuk, Yaroslav Zhumagulov +1
The paper introduces graphene nanohelicoids—helically wrapped graphene nanoribbons—and uses tight‑binding calculations to show that their electronic band structures exhibit width‑d…
Efficient Magnetic Spin-Filtering and Persistent Spin-Currents in Lifshitz-Transitioned Altermagnets: A Route to Open-Orbit Spintronics
Wun-Hao Kang, Yu-Ting Hsiao, Jozef Genzor +3
Altermagnets offer a unique venue for spin transport due to their vanishing net magnetization and momentum-dependent spin splitting. We demonstrate that a homotopic Lifshitz transi…
Study of the Nonlinear Dependence of Anomalous Hall Conductivity on Magnetization in Weak Itinerant Ferromagnet ZrZn2
Surasree Sadhukhan, Stepan S. Tsirkin, Yaroslav Zhumagulov +1
As opposed to the ordinary Hall effect, the anomalous Hall effect (AHE) remained unexplained for decades, and, amazingly, some misconceptions have survived even now, in particular,…
Coupling between CaWO phonons and Er dopants
Mikhael T. Sayat, Federico Pisani, Hin Lok Chang +8
We investigate the lattice dynamics of CaWO, a promising host crystal for erbium-based quantum memories, using inelastic neutron scattering together with density-functional per…
