Higher-order nonadiabaticity governs the temperature dependence of the phonon spectrum
Nina Girotto Erhardt, Samuel Poncé
Nonadiabatic effects determine the frequency and linewidth of coupled phonon modes, shape of Kohn anomalies and have important implications on many material properties. State-of-th…
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…
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…
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…
