Light-induced Orbital and Spin Magnetism in , , and Transition Metals
Theodoros Adamantopoulos, Dongwook Go, Peter M. Oppeneer +1
Understanding the coherent interplay of light with the magnetization in metals has been a long-standing problem in ultrafast magnetism. While it is known that when laser light acts…
Ultrafast photoinduced phase transition in the antiferromagnetic Dirac semimetal EuAgAs
Hao Liu, Chen Zhang, Qi-Yi Wu +12
We report the observation of a light-induced subpicosecond phase transition in the antiferromagnetic Dirac semimetal EuAgAs, achieved through ultrafast optical excitation. Using ul…
Weak Ferromagnetism in Altermagnets from Alternating -Tensor Anisotropy
Daegeun Jo, Dongwook Go, Yuriy Mokrousov +3
Altermagnets are magnetic materials with antiferromagnetic spin ordering but exhibit ferromagnetic properties. Understanding the microscopic origin of the latter is a central probl…
Harnessing magnetic octupole Hall effect to induce torque in altermagnets
Seungyun Han, Daegeun Jo, Insu Baek +2
d-wave altermagnets have magnetic octupoles as their order parameters [Phys. Rev. X 14, 011019 (2024)]. We theoretically show that magnetic octupoles injected from outside generate…
Unveiling the 5 electron hybridization process in UPdAl via ARPES and Time-resolved PES
Jiao-Jiao Song, Qi-Yi Wu, Chen Zhang +15
This study investigates the 5-electron-conduction electron hybridization process in the heavy fermion superconductor UPdAl using a combination of angle-resolved photoemi…
Doping dependence and multichannel mediators of superconductivity: Calculations for a cuprate model
Fabian Schrodi, Alex Aperis, Peter M. Oppeneer
We study two aspects of the superconductivity in a cuprate model system, its doping dependence and the influence of competing pairing mediators. We first include electron-phonon in…
Demagnetization dynamics after noncollinear dual optical excitation
Sergii Parchenko, Matthias Riepp, Simon Marotzke +4
We explore the impact of optical excitation using two interfering ultrashort optical pulses on ultrafast magnetization dynamics. Our investigation focuses on Pt/Co/Pt multilayers a…
Direct observation of nanometer-scale orbital angular momentum accumulation
Juan Carlos Idrobo, Ján Rusz, Gopal Datt +6
Conversion of charge to orbital angular momentum through the orbital Hall effect (OHE) holds transformative potential for the development of orbital-based electronics, however, it…
Relocalization of Uranium 5f Electrons in Antiferromagnetic Heavy Fermion Superconductor UPdAl: Insights from Angle-Resolved Photoemission Spectroscopy
Jiao-Jiao Song, Chen Zhang, Qi-Yi Wu +15
We investigate the antiferromagnetic heavy fermion superconductor UPdAl, employing angle-resolved photoemission spectroscopy to unravel the complex electronic structure of…
