A high-repetition rate attosecond light source for time-resolved coincidencespectroscopy
Sara Mikaelsson, Jan Vogelsang, Chen Guo +12
Attosecond pulses, produced through high-order harmonic generation in gases, have been successfully used for observing ultrafast, sub-femtosecond electron dynamics in atoms, molecu…
Few-cycle lightwave-driven currents in a semiconductor at high repetition rate
Fabian Langer, Yen-Po Liu, Zhe Ren +9
When an intense, few-cycle light pulse impinges on a dielectric or semiconductor material, the electric field will interact nonlinearly with the solid, driving a coherent current.…
Relaxation Oscillations and Ultrafast Emission Pulses in a Disordered Expanding Polariton Condensate
Maciej Pieczarka, Marcin Syperek, Łukasz Dusanowski +5
Semiconductor microcavities are often influenced by structural imperfections, which can disturb the flow and dynamics of exciton-polariton condensates. Additionally, in exciton-pol…
Real-time observation of interfering crystal electrons in high-harmonic generation
M. Hohenleutner, F. Langer, O. Schubert +5
Accelerating and colliding particles has been a key strategy to explore the texture of matter. Strong lightwaves can control and recollide electronic wavepackets, generating high-h…
Sub-cycle control of terahertz high-harmonic generation by dynamical Bloch oscillations
O. Schubert, M. Hohenleutner, F. Langer +8
Ultrafast charge transport in strongly biased semiconductors is at the heart of highspeed electronics, electro-optics, and fundamental solid-state physics. Intense light pulses in…
