Observation of non-adiabatic Landau-Zener tunneling among Floquet states
Yun Yen, Marcel Reutzel, Andi Li +3
Electromagnetic fields not only induce electronic transitions but also fundamentally modify the quantum states of matter through strong light-matter interactions. As one establishe…
Plasmonically assisted channels of photoemission from metals
Dino Novko, Vito Despoja, Marcel Reutzel +3
We analyse recently measured nonlinear photoemission spectra from Ag surfaces that reveal resonances whose energies do not scale with the applied photon energy but stay pinned to m…
Towards full surface Brillouin zone mapping by coherent multi-photon photoemission
Andi Li, Namitha Ann James, Tianyi Wang +3
We report a novel approach for coherent multi-photon photoemission band mapping of the entire Brillouin zone with infrared light that is readily implemented in a laboratory setting…
Excitation of two-photon photoemission where epsilon is near zero on Ag(111)
Marcel Reutzel, Andi Li, Branko Gumhalter +1
Because silver has epsilon-near-zero (ENZ) in the near-UV spectral region, its optical response is expected to be dominantly plasmonic and nonperturbatively nonlinear. The ENZ prop…
Coherent two-dimensional multiphoton photoelectron spectroscopy of metal surfaces
Marcel Reutzel, Andi Li, Hrvoje Petek
Light interacting with metals elicits an ultrafast coherent many-body screening response on sub- to few-femtosecond time-scales, which makes its experimental observation challengin…
