Robust spin splitting and fermiology in a layered altermagnet
Alessandro De Vita, Chiara Bigi, Davide Romanin +42
Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…
Photoinduced Electronic Band Dynamics and Defect-mediated Surface Potential Evolution in PdSe
Omar Abdul-Aziz, Manuel Tuniz, Wibke Bronsch +9
We use time- and angle-resolved photoemission spectroscopy (TR-ARPES) combined with density functional theory to investigate ultrafast carrier dynamics in low-symmetry layered semi…
Quench of the electronic order in a strongly-coupled charge-density-wave system by enhanced lattice fluctuations
Manuel Tuniz, Denny Puntel, Wibke Bronsch +5
Charge-density-wave (CDW) materials having a strong electron-phonon coupling provide a powerful platform for investigating the intricate interplay between lattice fluctuations and…
Anomalous spin-optical helical effect in Ti-based kagome metal
Federico Mazzola, Wojciech Brzezicki, Chiara Bigi +32
The kagome lattice stands as a rich platform for hosting a wide array of correlated quantum phenomena, ranging from charge density waves and superconductivity to electron nematicit…
Unveiling exciton formation: exploring the early stages in time, energy and momentum domain
Valentina Gosetti, Jorge Cervantes-Villanueva, Selene Mor +9
Resolving the early-stage dynamics of exciton formation following non-resonant photoexcitation in time, energy, and momentum is quite challenging due to their inherently fast times…
Van der Waals engineering of ultrafast carrier dynamics in magnetic heterostructures
Paulina Majchrzak, Yuntian Liu, Klara Volckaert +10
Heterostructures composed of the intrinsic magnetic topological insulator MnBiTe and its non-magnetic counterpart BiTe host distinct surface electronic band structu…
