Evolution of ac conductivity in nonequilibrium warm dense gold.
Zhijiang Chen,Bastian Holst,S. E. Kirkwood,Vahit Sametoglu,M. Reid,Ying Y. Tsui,Vanina Recoules,Andrew Ng +7 more
TL;DR: Using a chirped pulse probe technique, this article obtained single shot measurements of temporal evolution of ac conductivity at 1.55 eV (800 nm) during electron energy relaxation in nonequilibrium warm dense gold with energy densities up to $4.
Journal ArticleDOI

Silkin,Eugene V. Chulkov,Eugene V. Chulkov,Pedro M. Echenique,Pedro M. Echenique,Hrvoje Petek,Hrvoje Petek +17 more
TL;DR: In this article, the Coulomb interaction was used to determine the binding energy of the atoms and molecules at low coverage (less than 0.1 monolayer) on noble metal [Cu(111) and Ag(111)] surfaces.
Journal ArticleDOI
Ab initio model of optical properties of two-temperature warm dense matter
Bastian Holst,V. Recoules,Stephane Mazevet,Marc Torrent,Andrew Ng,Zhijiang Chen,S. E. Kirkwood,Vahit Sametoglu,M. Reid,Ying Y. Tsui +9 more
TL;DR: In this paper, Chen et al. presented a model to describe thermophysical and optical properties of two-temperature systems consisted of heated electrons and cold ions in a solid lattice that occur during ultrafast heating experiments.
Journal ArticleDOI
Simulation of two-photon photoemission from the bulk s p -bands of Ag(111)
TL;DR: In this paper, the two-photon photoemission spectrum was found to consist mainly of nonresonant direct transitions from the lower to the upper $sp$-band across the $L$-projected band gap.
Journal ArticleDOI
Angle-dependent study of a direct optical transition in the sp bands of Ag(111) by one- and two-photon photoemission
Aimo Winkelmann,Aimo Winkelmann,Vahit Sametoglu,Jin Zhao,Atsushi Kubo,Atsushi Kubo,Hrvoje Petek +6 more
TL;DR: In this article, angle-dependent photoemission spectra for one-photon and twophoton excitation from Ag(111) were measured using a nearly free-electron model for the initial and final states involved.
