Density dependent exciton dynamics and L valley anisotropy in germanium
Markus Stein, Christian Lammers, Phillip Springer +4
Optical pump-THz probe spectroscopy is used to investigate the exciton formation dynamics and its intensity dependence in bulk Ge. Associated with the intra-excitonic 1s-2p transit…
Coherent cyclotron motion beyond Kohn's theorem
T. Maag, A. Bayer, S. Baierl +10
In solids, the high density of charged particles makes many-body interactions a pervasive principle governing optics and electronics[1-12]. However, Walter Kohn found in 1961 that…
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…
Comment on "Nonlinear fluctuations and dissipation in matter revealed by quantum light"
M. Kira, S. W. Koch, S. T. Cundiff
In a recent paper [Phys.~Rev.~A {\bf 91}, 053844 (2015)], Mukamel and Dorfman compare spectroscopies performed with classical vs.~quantum light, and conclude that \textit{nonlinear…
Influence of bound and unbound electron-hole-pair populations on the excitonic luminescence in semiconductor quantum wells
W. Hoyer, M. Kira, S. W. Koch
A fully microscopic theory for the spontaneous emission from semiconductors is discussed. The theory is evaluated for a quantum-well system and the role of excitonic and unbound el…
