Anti-Stokes photoluminescence (ASPL) is an up-conversion phonon-assisted process of radiative recombination of photoexcited charge carriers when the ASPL photon energy is above the excitation one. This process can be very efficient in nanocrystals (N

The photoluminescence peculiarities and the excited state absorption of the tetrapod-shaped CdTe/CdSe nanocrystals are studied in the single-photon excitation regime. A giant blue shift (≈ 129 meV) of the charge-transfer photoluminescence spectra i

Theory of spin noise in low dimensional systems and bulk semiconductors is reviewed. Spin noise is usually detected by optical means, continuously measuring the rotation angle of the polarization plane of the probe beam passing through the sample. Sp

In multi-channel tunneling systems quantum interference effects modify tunneling conductance spectra due to Fano effect. We investigated the impact of Hubbard type Coulomb interaction on tunneling conductance spectra for the system formed by several

Coupled oscillators are one of the basic models in nonlinear dynamics. Here, we study numerically and analytically the spectra of two harmonic oscillators with stochastically fluctuating coupling and driving forces reproducing a thermostat. We show t

Non-stationary spin-dependent transport through the interacting single-level quantum dot coupled to ferromagnetic leads with non-collinear magnetizations has been analyzed theoretically. The non-stationary transport is investigated within the theoret

We propose an interpolation scheme to describe pair correlations in crystals with many-body interactions that requires only information on relative displacements for the nearest neighbours and in the long range. Using crystalline Ni as a test case, t
