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…
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…
Robust spin splitting and fermiology in the layered altermagnet CoNb4Se8
Alessandro De Vita, Chiara Bigi, Davide Romanin +44
Altermagnetism defies conventional classifications of collinear magnetic phases, combining compensated magnetization with momentum-dependent, nonrelativistic spin splitting. While…
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…

Manuel Tuniz, Armando Consiglio, Ganesh Pokharel +10
The kagome geometry is an example of frustrated configuration in which rich physics takes place, including the emergence of superconductivity and charge density wave (CDW). Among t…
Ultrafast Band Structure Dynamics in Bulk 1-VSe
Wibke Bronsch, Manuel Tuniz, Denny Puntel +4
Complex materials encompassing different phases of matter can display new photoinduced metastable states differing from those attainable under equilibrium conditions. These states…
Photoinduced dynamics of flat bands in the kagome metal CoSn
Denny Puntel, Wibke Bronsch, Manuel Tuniz +8
CoSn is a prototypical kagome compound showing lattice-born flat bands with suppressed bandwidth over large parts of the Brillouin zone. Here, by means of time- and angle-resolved…
