Journal ArticleDOI
Sub-cycle control of terahertz high-harmonic generation by dynamical Bloch oscillations
Olaf Schubert,Matthias Hohenleutner,F. Langer,Benedikt Urbanek,Christoph Lange,U. Huttner,D. Golde,Torsten Meier,Mackillo Kira,Stephan W. Koch,Rupert Huber +10 more
TL;DR: In this article, a phase-stable, high-harmonic transients over the whole frequency range of 0.1-675 THz were obtained. But the frequency of 30 THz was not considered.
Journal ArticleDOI
Real-time observation of interfering crystal electrons in high-harmonic generation
Matthias Hohenleutner,F. Langer,Olaf Schubert,Matthias Knorr,U. Huttner,Stephan W. Koch,Mackillo Kira,Rupert Huber +7 more
TL;DR: This work studies high-harmonic generation in a bulk solid directly in the time domain, and reveals a new kind of strong-field excitation in the crystal that justifies the hope for all-optical band-structure reconstruction and lays the foundation for possible quantum logic operations at optical clock rates.
Journal ArticleDOI
Quantitative optical trapping of single gold nanorods.
TL;DR: The interaction between the electromagnetic field of an optical trap and a single gold nanorod correlated with particle polarizability, which is a function of both particle volume and aspect ratio.
Journal ArticleDOI
Absorption properties of metal-semiconductor hybrid nanoparticles.
Ehud Shaviv,Olaf Schubert,Marcelo Alves-Santos,Guido Goldoni,Rosa Di Felice,Fabrice Vallée,Natalia Del Fatti,Uri Banin,Carsten Sönnichsen +8 more
TL;DR: This study studies the absorption of hybrid metal-semiconductor nanoparticles by comparing experimental results with simulations using the discrete dipole approximation method (DDA) employing dielectric functions of the bare components as inputs and finds a shortcoming of the electrodynamic model.
Journal ArticleDOI
Single-cycle multiterahertz transients with peak fields above 10 MV/cm.
F. Junginger,Alexander Sell,Olaf Schubert,Bernhard Mayer,Daniele Brida,Marco Marangoni,Giulio Cerullo,Alfred Leitenstorfer,Rupert Huber +8 more
TL;DR: Phase-locked single-cycle transients with frequency components between 1 and 60THz and peak fields of up to 12MV/cm are generated as the idler wave of a parametric amplifier to achieve broadband conversion in GaSe nonlinear crystals and the group velocities of signal and idler components are matched.
