Solids consist of 1022–1023 particles per cubic centimetre, interacting through infinite-range
Coulomb interactions. The linear response of a solid to a weak external perturbation is well …

A valley-selective circular dichroism and a pronounced spin-valley locking in monolayer
transition metal dichalcogenides (TMDCs) enable the investigation of new many-body …

We present time-integrated four-wave mixing measurements on monolayer MoSe2 in
magnetic fields up to 25 T. The experimental data together with time-dependent density …

The photon energy, irradiation time, and sample temperature dependences of laser-
enhanced NMR spectra from semi-insulating GaAs at 9.4 T were measured. These data …

The influence of four-particle correlations on the nonlinear optics of a semiconductor
microcavity is determined by a pump-and-probe investigation. Experiments are performed …

By means of degenerate four-wave mixing (FWM), we investigate the quantum coherence of
electron-hole pairs in the presence of a two-dimensional electron gas in modulation-doped …

Six-wave-mixing signals from a ZnSe quantum well are analyzed experimentally and with a
microscopic density-matrix description using the dynamics-controlled-truncation scheme …

The femtosecond inter-Landau-level dynamics of a two-dimensional electron gas in a large
magnetic field is investigated by degenerate four-wave mixing on modulation doped …

Recent theories of highly excited semiconductors are based on two formalisms, referring to
complementary experimental conditions, the real-time nonequilibrium Green's function …

The memory structure induced by coherent transitions to the exciton-exciton scattering
continuum is shown to have significant influence on spectrally resolved four-wave-mixing …
