Staged emergence of anomalous Hall transport in a correlated uranium Weyl semimetal

Sabin Regmi, Shuxiang Zhou, Chandan K. Singh +9

Understanding how electronic correlations reshape topological states remains a central challenge in quantum materials. Here we investigate the uranium ferromagnet UPS using magneto…

Magnetism in AV3Sb5 (A = Cs, Rb, K): Complex Landscape of the Dynamical Magnetic Textures

Debjani Karmakar, Manuel Pereiro, Md. Nur Hasan +10

We have investigated the dynamical magnetic properties of the V-based kagome stibnite compounds by combining the ab-initio calculated magnetic parameters of a spin Hamiltonian like…

Magnetism in AV3Sb5 (Cs, Rb, K): Origin and Consequences for the Strongly Correlated Phases

Md. Nur Hasan, Ritadip Bharati, Johan Hellsvik +10

The V-based kagome systems AV3Sb5 (A = Cs, Rb and K) are unique by virtue of the intricate interplay of non-trivial electronic structure, topology and intriguing fermiology, render…

Ultrafast Demagnetization through Femtosecond Generation of Non-thermal Magnons

Markus Weißenhofer, Peter M. Oppeneer

Ultrafast laser excitation of ferromagnetic metals gives rise to correlated, highly non-equilibrium dynamics of electrons, spins and lattice, which are, however, poorly described b…

First-principles calculation of orbital Hall effect by Wannier interpolation: Role of orbital dependence of the anomalous position

Dongwook Go, Hyun-Woo Lee, Peter M. Oppeneer +2

The position operator in a Bloch representation acquires a gauge correction in the momentum space on top of the canonical position, which is called the anomalous position. We show…

Ab initio investigation of laser-induced ultrafast demagnetization of L1 FePt: Intensity dependence and importance of electron coherence

M. S. Mrudul, Peter M. Oppeneer

We theoretically investigate the optically-induced demagnetization of ferromagnetic FePt using the time-dependent density functional theory (TDDFT). We compare the demagnetization…
