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…
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…
Out-of-equilibrium charge redistribution in a copper-oxide based superconductor by time-resolved X-ray photoelectron spectroscopy
Denny Puntel, Dmytro Kutnyakhov, Lukas Wenthaus +10
Charge-transfer excitations are of paramount importance for understanding the electronic structure of copper-oxide based high-temperature superconductors. In this study, we investi…
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…
Ultrafast all-optical manipulation of the charge-density-wave in VTe
Manuel Tuniz, Davide Soranzio, Davide Bidoggia +6
The charge-density wave (CDW) phase in the layered transition-metal dichalcogenide VTe is strongly coupled to the band inversion involving vanadium and tellurium orbitals. In…
Dynamics and Resilience of the Charge Density Wave in a bilayer kagome metal
Manuel Tuniz, Armando Consiglio, Denny Puntel +22
Long-range electronic order descending from a metallic parent state constitutes a rich playground to study the intricate interplay of structural and electronic degrees of freedom.…
Ultrafast manipulation of the NiO antiferromagnetic order via sub-gap optical excitation
Xiaocui Wang, Robin Y. Engel, Igor Vaskivskyi +19
Wide-band-gap insulators such as NiO offer the exciting prospect of coherently manipulating electronic correlations with strong optical fields. Contrary to metals where rapid depha…
Photoinduced nematic state in FeSeTe
Laura Fanfarillo, Damir Kopić, Andrea Sterzi +8
FeSeTe compounds present a complex phase diagram, ranging from the nematicity of FeSe to the magnetism of FeTe. We focus on FeSeTe, where the…
