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…
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…
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…
Ultrafast low-energy photoelectron diffraction for the study of surface-adsorbate interactions with 100 femtosecond temporal resolution
Hermann Erk, Carl Eric Jensen, Stephan Jauernik +1
An ultrafast photoemission-based low-energy electron diffraction experiment with monolayer surface sensitivity is presented. In a first experiment on tin-phthalocyanine adsorbed on…
A combined laser-based ARPES and 2PPES study of Td-WTe
Petra Hein, Stephan Jauernik, Hermann Erk +5
Laser-based angle-resolved photoemission spectroscopy (ARPES) and two-photon photoemission spectroscopy (2PPES) are employed to study the valence electronic structure of the Weyl s…
Mode-resolved reciprocal space mapping of electron-phonon interaction in the Weyl semimetal candidate Td-WTe
P. Hein, S. Jauernik, H. Erk +5
The selective excitation of coherent phonons provides unique capabilities to control fundamental properties of quantum materials on ultrafast time scales. For instance, in the pres…
