Phonon-induced pseudogap phase in TiSe
Sotirios Fragkos, Nina Girotto Erhardt, Evgenia Symeonidou +9
To comprehend quantum ordered states, such as charge density waves (CDW), in layered transition metal dichalcogenides (TMDCs), it is essential to uncover their underlying normal st…
Excited States Band Mapping and Ultrafast Nonequilibrium Dynamics in Topological Dirac Semimetal 1T-ZrTe
Sotirios Fragkos, Evgenia Symeonidou, Emile Lasserre +7
We performed time- and polarization-resolved extreme ultraviolet momentum microscopy on topological Dirac semimetal candidate 1T-ZrTe. Excited states band mapping uncovers the…
Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
Interplay between altermagnetic order and crystal symmetry probed using magnetotransport in epitaxial altermagnet MnTe
Himanshu Bangar, Polychronis Tsipas, Prasanna Rout +5
Altermagnets are a new class of magnetic materials characterized by fully compensated spins arranged in alternating local structures, allowing for spin-split bands similar to those…
