Journal ArticleDOI
Femtosecond tracking of carrier relaxation in germanium with extreme ultraviolet transient reflectivity
Christopher J. Kaplan,Peter M. Kraus,Andrew D. Ross,Michael Zürch,Scott K. Cushing,Marieke F. Jager,Hung-Tzu Chang,Eric M. Gullikson,Daniel M. Neumark,Daniel M. Neumark,Stephen R. Leone,Stephen R. Leone +11 more
TL;DR: In this paper, the authors derived the transient dielectric function of crystalline germanium on femtosecond to picosecond time scales following photoexcitation by broadband visible-to-infrared (VIS/NIR) pulses.
Journal ArticleDOI
Attosecond Time-Domain Measurement of Core-Level-Exciton Decay in Magnesium Oxide.
Romain Géneaux,Christopher J. Kaplan,Lun Yue,Andrew D. Ross,Jens Egebjerg Bækhøj,Peter M. Kraus,Hung-Tzu Chang,Alexander Guggenmos,Mi-Ying Huang,Michael Zürch,Kenneth J. Schafer,Daniel M. Neumark,Daniel M. Neumark,Mette B. Gaarde,Stephen R. Leone,Stephen R. Leone +15 more
TL;DR: Core-level-exciton states of magnesium oxide are studied in the time domain at the Mg L L_{2,3} edge with attosecond transient reflectivity spectroscopy and it is revealed that the infrared pulse shifts the energy of bright (dipole-allowed) core- level- Exciton states as well as induces features arising from dark core-level excitons.
Journal ArticleDOI

TL;DR: A table-top beamline providing a soft X-ray supercontinuum extending up to 370 eV from high-order harmonic generation with sub-13 fs 1300 nm driving pulses and simultaneous production of sub-5 fs pulses centered at 800 nm is presented.
Journal ArticleDOI
Coherent energy exchange between carriers and phonons in Peierls-distorted bismuth unveiled by broadband XUV pulses
Romain Géneaux,Romain Géneaux,Iurii Timrov,Christopher J. Kaplan,Andrew D. Ross,Peter Kraus,Stephen R. Leone,Stephen R. Leone +7 more
TL;DR: In this paper, the authors used transient reflectivity in the extreme ultraviolet to quantify both responses in photoexcited bismuth in a single measurement, and revealed a coherent, bidirectional energy exchange between carriers and phonons, which is a dynamical counterpart of the static Peierls-Jones distortion.
