Light-induced renormalization of the band structure of chiral tellurium
G. Gatti, N. Tancogne-Dejean, H. Hübener +11
Chirality in tellurium derives from a Peierls distortion driven by strong electron-phonon coupling, making this material a unique candidate for observing a light-induced topologica…
First-principles modelling for time-resolved ARPES under different pump-probe conditions
Umberto De Giovannini, Shunsuke A. Sato, Hannes Hübener +1
First-principles methods for time-resolved angular resolved photoelectron spectroscopy play a pivotal role in providing interpretation and microscopic understanding of the complex…
Monitoring in real time the photon-dressing and undressing of quasiparticles from first principles time-resolved photoelectron spectroscopy
Umberto De Giovannini, Hannes Hübener, Angel Rubio
Optical pumping of solids creates a non-equilibrium electronic structure where electrons and photons combine to form quasiparticles of dressed electronic states. The resulting shif…
A first principles TDDFT framework for spin and time-resolved ARPES in periodic systems
Umberto De Giovannini, Hannes Hübener, Angel Rubio
We present a novel theoretical approach to simulate spin, time and angular-resolved photoelectron spectroscopy (ARPES) from first principles that is applicable to surfaces, thin fi…
Efficient and accurate modeling of electron photoemission in nanostructures with TDDFT
Philipp Wopperer, Umberto De Giovannini, Angel Rubio
We review different computational methods for the calculation of photoelectron spectra and angular distributions of atoms and molecules when excited by laser pulses using time-depe…
Modeling electron dynamics coupled to continuum states in finite volumes
Umberto De Giovannini, Ask Hjorth Larsen, Angel Rubio
Absorbing boundaries are frequently employed in real-time propagation of the Schrödinger equation to remove spurious reflections and efficiently emulate outgoing boundary condition…
