This paper is a review of the present status of the problem of the properties of the dielectric
function of matter. It is shown that the dielectric function ε (q, ω) obeys the Kramers-Kronig …

Theoretical and experimental work concerning high-temperature superconductors in general
and cuprates in particular is reviewed. A detailed analysis of the current knowledge of the …

… Instead, it forms exotic crystal structures, remaining an insulator and retaining its quasimolecular
structure (eg, see the review [6]). Unfortunately, the `unwillingness' of hydrogen to …

It is shown that due to the strong electron-phonon interaction the usual Fermi-liquid description
of the electron system is violated in the normal phase of HTSC metals (T > T c ). As a …

A critical temperatureT c of a superconducting transition is calculated for a rather general form
of the electron-electron interaction. It is shown that even if both the energy and momentum …

Selective study of the electron transport chain components in living mitochondria is essential
for fundamental biophysical research and for the development of new medical diagnostic …

Orange carotenoid protein (OCP) is the photoactive protein that is responsible for high light
tolerance in cyanobacteria. We studied the kinetics of the OCP photocycle by monitoring …

Here we introduce a new solvent-free preparation method for hybrid metal halide perovskites
involving the direct reaction of metallic lead with polyiodide melts. We discovered new …

Orange carotenoid protein (OCP) is a water-soluble photoactive protein responsible for a
photoprotective mechanism of nonphotochemical quenching in cyanobacteria. Under blue–…

… Our data show that restoration of static quenching (eg due to H-bond formation or other
interactions of Trp residues) precedes the changes in carotenoid-protein absorption. We …
