ABSTRACT
Time-resolved optical measurements at low temperatures reveal finite size effects for excitons trapped in semiconductor microcrystallites embedded in a simple borosilicate glass. The excitation lifetimes are significantly shorter than those in comparable bulk material, with a marked dependence on crystallite size. The results are interpreted as an effect of three-dimensional confinement with ‘‘box’’ dimensions comparable to the exciton diameter.

    We analyze the response of an ensemble of 1s-excitons driven by a femtosecond optical pulse, beyond traditional “slowly varying amplitudes” approach. For optical pulses of a given duration it is shown that the off-resonance optical field can evolve into a stable soliton with nonzero...

    Intersubband and intrasubband scattering of hot electron-hole pairs is studied with picosecond infrared pulses. The carrier distribution function is derived directly from the transient absorption spectra after selective excitation of carriers to the n=1 and 2 subbands. Band filling of the n=1...

    Recent advances in the spectroscopies of the second order processes both in the optical region and in the soft x-ray region are reviewed from a theoretical standpoint. A peculiar role of the breathing and oscillating spectral hole in the femtosecond pump-probe experiments is pointed out. The...

    A detailed time resolved investigation of the photoluminescence of a thin tetracene film deposited on highly oriented pyrolytic graphite is presented. In agreement with Lim et al. [Phys. Rev. Lett. 92, 107402 (2004)], we find strong evidence for superradiance: an increase of the relative...

    We examine a mechanism by which excitons undergo ultrafast relaxation in common monolayer transition metal dichalcogenides. It is shown that at densities ≈1 × 1011 cm-2 and temperatures ≤60 K, excitons in well known monolayers (MoS2, MoSe2, WS2, and WSe2) exist as point-like...

    Developments in optoelectronics and spin-optronics based on transition metal dichalcogenide monolayers (MLs) need materials with efficient optical emission and well-defined transition energies. In as-exfoliated MoS2 MLs, the photoluminescence (PL) spectra even at low temperature consist...

    We investigate the molecular dynamics of pyrazine after excitation to the S2 electronic state by using the time-dependent discrete variable representation (TDDVR) method.
