Excitons and Optical Response in Excitonic Insulator Candidate TiSe
Dino Novko
The origin of the charge density wave (CDW) phase in TiSe is a highly debated topic, with lattice and excitonic correlations proposed as the main driving mechanisms. One of the…
Unconventional Materials for Light Dark Matter Detection
Yonit Hochberg, Dino Novko, Rotem Ovadia +1
We propose the use of several unconventional materials as detectors for dark matter with mass beneath the MeV scale. These include the transition-metal dichalcogenide TiSe host…
Understanding the origin of superconducting dome in electron-doped MoS monolayer
Nina Girotto Erhardt, Jan Berges, Samuel Poncé +1
We investigate the superconducting properties of molybdenum disulphide (MoS) monolayer across a broad doping range, successfully recreating the so far unresolved superconductin…
Electron-mediated anharmonicity and its role in the Raman spectrum of graphene
Nina Girotto Erhardt, Aloïs Castellano, J. P. Alvarinhas Batista +4
The Raman active G mode in graphene exhibits strong coupling to electrons, yet the comprehensive treatment of this interaction in the calculation of its temperature-dependent Raman…
