An efficient approach to electron-phonon coupling calculations of heterostructures within an all-electron framework
Ignacio Gonzalez Oliva, Sebastian Tillack, Fabio Caruso +2
A major challenge in calculating electron-phonon coupling at interfaces from first principles is the prohibitive computational cost due to the large supercells involved. Here, we p…
X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Nonlinear electron-phonon coupling drives light-induced symmetry switching in charge-density waves
Christoph Emeis, Fabio Caruso
Ultrafast optical excitation in charge-density wave (CDW) crystals can transiently suppress long-range order, driving the lattice toward higher symmetry on femtosecond timescales.…
Coherent Phonon-Driven Band Renormalizations in 1T-MoTe
Carl E. Jensen, Christoph Emeis, Stephan Jauernik +3
Here, we investigate phonon mode- and electron band-selective electron-phonon couplings in centrosymmetric 1T-MoTe using time- and angle-resolved photoemission spectroscopy…
Impact of electron-phonon interaction on the electronic structure of interfaces between organic molecules and a MoS monolayer
Ignacio Gonzalez Oliva, Sebastian Tillack, Fabio Caruso +2
By means of first-principles calculations, we investigate the role of electron-phonon interaction in the electronic structure of hybrid interfaces, formed by MoS and monolayers…
Electronic correlation effects in the response of graphene and MoS2 monolayers to the impact of highly-charged ions
Giorgio Lovato, Michael Bonitz, Karsten Balzer +2
The interaction of highly-charged ions with monolayers of graphene and MoS2 is theoretically investigated based on nonequilibrium Green Functions (NEGF). In a recent paper [Niggas…
Coherent phonon control beyond amplitude saturation in a sliding ferroelectric
Jan Gerrit Horstmann, Christoph Emeis, Andrin Caviezel +5
The breakdown of Hooke's law marks the onset of nonlinear behaviour: when displacements become large, restoring forces weaken and conventional proportionality fails. In quantum mat…
Momentum-Resolved Signatures of Carrier Screening Effects on Electron-Phonon Coupling in MoS
Yiming Pan, Patrick-Nigel Hildebrandt, Daniela Zahn +5
Electron-phonon coupling is central to many condensed matter phenomena. Harnessing these effects for novel material functionality in materials always involves non-equilibrium elect…
Origin of phonon decoherence
Yiming Pan, Christoph Emeis, Stephan Jauernik +2
Phonon decoherence determines the characteristic timescales over which coherent lattice vibrations decay, making it a crucial process for understanding the non-equilibrium dynamics…
The 2025 Roadmap to Ultrafast Dynamics: Frontiers of Theoretical and Computational Modelling
Fabio Caruso, Michael A. Sentef, Claudio Attaccalite +27
The exploration of ultrafast phenomena is a frontier of condensed matter research, where the interplay of theory, computation, and experiment is unveiling new opportunities for und…
Phonon-mediated renormalization of exciton energies and absorption spectra in polar semiconductors
Maximilian Schebek, Pasquale Pavone, Claudia Draxl +1
We investigate the influence of vibrational screening on the excitonic and optical properties of solids based on first-principles electronic-structure calculations. We solve the Be…
Coherent Phonons and Quasiparticle Renormalization in Semimetals from First Principles
C. Emeis, S. Jauernik, S. Dahiya +5
Coherent phonons, light-induced coherent lattice vibrations in solids, provide a powerful route to engineer structural and electronic degrees of freedom using light. In this manusc…
Strain-induced activation of chiral-phonon emission in monolayer WS
Yiming Pan, Fabio Caruso
We report a theoretical investigation of the ultrafast dynamics of electrons and phonons in strained monolayer WS following photoexcitation. We show that strain substantially m…
A momentum-resolved view of polaron formation in materials
Tristan L Britt, Fabio Caruso, Bradley J Siwick
A combined experimental and computational methodology for interrogating the phonon contribution to polaron formation in real materials is developed. Using LiF as an example, we sho…
