Martin Schultze,Martin Schultze,Krupa Ramasesha,Chaitanya Das Pemmaraju,Shunsuke A. Sato,Desire Whitmore,Andrey Gandman,James S. Prell,Lauren J. Borja,David Prendergast,Kazuhiro Yabana,Daniel M. Neumark,Daniel M. Neumark,Stephen R. Leone,Stephen R. Leone +14 more
TL;DR: Attosecond extreme ultraviolet (XUV) spectroscopy is used to resolve the electron transfer from valence to conduction band states in semiconductors, and distinguished the electron dynamics—which proceed faster than a quadrillionth of a second after laser excitation—from the comparatively slower lattice motion of the silicon atomic nuclei.
Journal ArticleDOI

TL;DR: The Octopus project as mentioned in this paper provides a unique framework that allows us to describe non-equilibrium phenomena in molecular complexes, low dimensional materials, and extended systems by accounting for electronic, ionic, and photon quantum mechanical effects within a generalized time-dependent density functional theory.

Attosecond dynamical Franz-Keldysh effect in polycrystalline diamond

TL;DR: Attosecond transient absorption spectroscopy was applied to investigate the interaction between polycrystalline diamond and a few-femtosecond infrared pulse with intensity below the critical intensity of optical breakdown, and identified infrared induction of intraband currents as the main physical mechanism responsible for the observations.

Attosecond nonlinear polarization and light–matter energy transfer in solids

TL;DR: It is demonstrated that attosecond metrology extends the resolution to petahertz frequencies of visible light and Quantitative determination of dissipation within a signal manipulation cycle of only a few femtoseconds duration reveals the feasibility of dielectric optical switching at clock rates above 100 teraherz.

Ab initio multiscale simulation of high-order harmonic generation in solids
Isabella Floss,Christoph Lemell,Georg Wachter,Valerie Smejkal,Shunsuke A. Sato,Xiao-Min Tong,Kazuhiro Yabana,Joachim Burgdörfer +7 more
TL;DR: In this article, a multiscale simulation of solid-state high-order-harmonic generation was performed for dielectrics and it was shown that mesoscopic effects of the extended system, in particular the realistic sampling of the entire Brillouin zone, the pulse propagation in the dense medium, and the inhomogeneous illumination of the crystal, have a strong effect on the harmonic spectra.
