Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
Strong chiral dichroism in above threshold ionization and ionization rates from locally-chiral light
Ofer Neufeld, Hannes Hübener, Angel Rubio +1
We derive here a new highly selective photoelectron-based chirality-sensing technique that utilizes 'locally-chiral' laser pulses. We show that this approach results in strong chir…
Nonlinear phononics in 2D SnTe: a ferroelectric material with phonon dynamical amplification of electric polarization
Dongbin Shin, Shunsuke A. Sato, Hannes Hübener +3
Ultrafast optical control of ferroelectricity using intense terahertz fields has attracted significant interest. Here we show that the nonlinear interactions between two optical ph…
Unravelling the intertwined atomic and bulk nature of localised excitons by attosecond spectroscopy
Matteo Lucchini, Shunsuke A. Sato, Giacinto D. Lucarelli +9
The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasiparticles called excitons. The ma…
Direct measurement of electron-phonon coupling with time-resolved ARPES
Umberto De Giovannini, Hannes Hübener, Shunsuke A. Sato +1
Time and angular resolved photoelectron spectroscopy is a powerful technique to measure electron dynamics in solids. Recent advances in this technique have facilitated band and ene…
How Circular Dichroism in time- and angle-resolved photoemission can be used to spectroscopically detect transient topological states in graphene
Michael Schüler, Umberto De Giovannini, Hannes Hübener +4
Pumping graphene with circularly polarized light is the archetype of light-tailoring topological bands. Realizing the induced Floquet-Chern insulator state and tracing clear experi…
