Electron emission from plasmonically induced Floquet bands at metal surfaces
Branko Gumhalter, Dino Novko, Hrvoje Petek
We explore the possibility of existence of plasmonically generated electronic Floquet bands at metal surfaces by studying the gauge transformed electron-surface plasmon interaction…
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…
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…
On the combined use of GW approximation and cumulant expansion in the calculations of quasiparticle spectra: The paradigm of Si valence bands
Branko Gumhalter, Vjekoslav Kovač, Fabio Caruso +2
Since the earliest implementations of the various GW approximations and cumulant expansion in the calculations of quasiparticle propagators and spectra, several attempts have been…
Transient excitons at metal surfaces
Xuefeng Cui, Cong Wang, Adam Argondizzo +3
Excitons, electron-hole pairs bound by the Coulomb potential, are fundamental quasiparticles of coherent light-matter interaction energizing processes from photosynthesis to optoel…
Suppression of inelastic bound state resonance effects by the dimensionality of atom-surface scattering event
A. Siber, B. Gumhalter
We develop a multidimensional coupled channel method suitable for studying the interplay of bound state resonance and phonon assisted scattering of inert gas atoms from solid surfa…
