The issue in your hands (Low-Temperature Spectroscopy and Optics) is dedicated to the memory of Antonina Fedorovna Prikhot'ko, whose centenary is celebrated by scientific community in 2006.

A notable role in understanding of microscopic electronic properties of high temperature superconductors (HTSC) belongs to angle resolved photoemission spectroscopy (ARPES). This technique supplies a direct window into ...

We consider the ectronic properties of empty single-wall nanotubes (SWNT) and SWNT filled with the fullerenle molecules (carbon «nano-peapod»). The first part of the review (section 2) is devoted mostly to the Luttinger ...

Structure and reactivity of the eight enolic forms (one chelated and seven non-chelated) of malonaldehyde and acetylacetone are compared through theoretical and experimental data. Ground-state geometries, energies, and ...

A spin-fermion and Landau–Ginzburg model for high-temperature superconductors are formulated and analyzed with unbiased numerical techniques. The study of the competition between d-wave superconductivity and antiferromagnetism ...

The low temperature bound of the decay rate of the excited surface electron states on liquid helium is theoretically studied. It is shown that the lifetime and dephasing time of the surface electron states are strongly ...

Electron or photon irradiation on H₂O adsorbed on the surface of rare gas solids induces the desorption of protonated water clusters, (H₂O)nH⁺. The yield and the size n distribution of cluster ions depend on the coverage, ...

We have studied theoretically how nonmagnetic dopants, which change the local coupling of spins to the host, affect the low-temperature thermodynamic characteristics of quasi-one-dimensional (Q1D) quantum spin antiferromagnets. ...

The theory of exciton condensation is given in two-dimensional systems under suggestion that condensation occurs in really space and condensed phase arises as a result of an attractive interaction between excitons. Due ...

Solid solutions (N₂)x(O₂)₁₋x have been investigated by infrared absorption measurements mainly in the O₂ and N₂ stretching regions, between 60–10 K, completing former similar studies by Raman scattering. We produced ...
