Femtosecond measurements of coherent effects arising from exciton bleaching in bulk GaAs
are reported. This phenomenon, which is characterized by spectral oscillatory structures, is …

Sequencing of whole cancer genomes has revealed an abundance of recurrent mutations
in gene-regulatory promoter regions, in particular in melanoma where strong mutation …

We study the influence of three laser beams on the center-of-mass motion of cold atoms with
internal energy levels in a tripod configuration. We show that, as for electrons in graphene, …

Quantum-confinement effects in CdSe microcrystallites in a glass matrix are investigated in
the nanosecond time domain. The results of pump–probe and single-beam absorption …

The possibility of creating dark states (a concept well known in atomic systems) in semiconductors
is discussed. Based on the semiconductor Bloch equations, the analysis shows that, …

Probe-transmission spectra are calculated for a semiconductor that is excited by ultrashort
pulses well above its band edge. Coherent coupling of the light field to the band-to-band …

Mutational signatures can reveal properties of underlying mutational processes and are
important when assessing signals of selection in cancer. Here, we describe the sequence …

Small intestine neuroendocrine tumor (SI-NET), the most common cancer of the small bowel,
often displays a curious multifocal phenotype with several tumors clustered together in a …

We develop an expression for the final temperature achieved by laser cooling of a trapped
three-level ion with the Λ configuration of states by employing an expansion in the photon …

We present a master equation that describes the dynamics of laser cooling of a trapped ion.
It is valid in the Lamb-Dicke limit and rests on an adiabatic elimination combined with a …
