Subcycle videography of lightwave-driven Landau-Zener-Majorana transitions in graphene
Vincent Eggers, Giacomo Inzani, Manuel Meierhofer +14
Strong light fields have unlocked previously unthinkable possibilities to tailor coherent electron trajectories, engineer band structures and shape emergent phases of matter all-op…
Tracing orbital images on ultrafast time scales
Robert Wallauer, Miriam Raths, Klaus Stallberg +10
Frontier orbitals, i.e., the highest occupied and lowest unoccupied orbitals of a molecule, generally determine molecular properties, such as chemical bonding and reactivities. Con…
Ultrafast dynamics of photocurrents in surface states of 3D topological insulators
Jens Güdde, Ulrich Höfer
This article reviews experimental work on the ultrafast electron dynamics in the topological surface state (TSS) of three-dimensional (3D) topological insulators (TIs) observed wit…
Intervalley scattering in MoS imaged by two-photon photoemission with a high-harmonic probe
Robert Wallauer, Johannes Reimann, Nico Armbrust +2
We report on the direct mapping of electron transfer in the momentum space of bulk MoS by means of time- and angle-resolved two-photon photoemission with a high-harmonic probe.…
Spectroscopy and Dynamics of a Two-Dimensional Electron Gas on top of Ultrathin Helium Films on Cu(111)
Nico Armbrust, Jens Güdde, Ulrich Höfer +2
Electrons in image-potential states on the surface of bulk helium represent a unique model system of a two-dimensional electron gas. Here, we investigate their properties in the ex…
