Spectroscopic signatures of persistent exciton condensation in a bulk magnetic topological insulator
Paulina Majchrzak, Chakradhar Sahoo, Manuel Tuniz +7
Exciton condensates are long-sought correlated quantum states arising from macroscopic coherence of bound electron-hole pairs. Although equilibrium and transient excitonic states h…
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…
Ultrafast light-driven optical rotation and hidden orders in bulk WSe
Emmanuele Cappelluti, Habib Rostami, Federico Cilento
Single-layer semiconducting transition-metal dichalcogenides, lacking point inversion symmetry, provide an efficient platform for valleytronics, where the electronic, magnetic, val…
Unveiling the physics of the spin-orbit coupling at the surface of a model topological insulator: from theory to experiments
Denny Puntel, Simone Peli, Wibke Bronsch +4
Spin-orbit interaction affects the band structure of topological insulators beyond the opening of an inverted gap in the bulk bands, and the understanding of its effects on the sur…
External screening and lifetime of exciton population in single-layer ReSe probed by time- and angle-resolved photoemission spectroscopy
Klara Volckaert, Byoung Ki Choi, Hyuk Jin Kim +7
The semiconductor ReSe is characterized by a strongly anisotropic optical absorption and is therefore promising as an optically active component in two-dimensional heterostruct…
Ultrafast Dynamics of Massive Dirac Fermions in Bilayer Graphene
Søren Ulstrup, Jens Christian Johannsen, Federico Cilento +14
Bilayer graphene is a highly promising material for electronic and optoelectronic applications since it is supporting massive Dirac fermions with a tuneable band gap. However, no c…
