Comparative study of phase transitions in polycrystalline and epitaxial BaTiO3 thin films by means of specific heat measurements
B. Strukov, S. Davitadze, V. Lemanov +3
The experimental data on the thermal properties of the nanostructured perovskite ferroelectrics are presented and analysed. The ability of the modified 3w method for specific heat…
Heat capacity of a thin membrane at very low temperature
O. V. Fefelov, J Bergli, Y M Galperin
We calculate the dependence of heat capacity of a free standing thin membrane on its thickness and temperature. A remarkable fact is that for a given temperature there exists a min…

The fine structure of excited excitonic states in a quantum dot with an embedded magnetic ion is studied theoretically and experimentally. The developed theory takes into account t…
Point contact spectroscopy of hopping transport: effects of a magnetic field
V. I. Kozub, A. A. Zyuzin, O. Entin-Wohlman +3
The conductance of a point contact between two hopping insulators is expected to be dominated by the individual localized states in its vicinity. Here we study the additional effec…
Two-Photon 2s<->1s Transitions during Recombination of Hydrogen in the Universe
E. E. Kholupenko, A. V. Ivanchik
Based on the standard cosmological model, we calculate the correction to the rate of two-photon 2s<->1s transitions in the hydrogen atom under primordial hydrogen plasma recombinat…
Heat blanketing envelopes and thermal radiation of strongly magnetized neutron stars
A. Y. Potekhin, G. Chabrier, D. G. Yakovlev
Strong (B >> 10^9 G) and superstrong (B > 10^{14} G) magnetic fields profoundly affect many thermodynamic and kinetic characteristics of dense plasmas in neutron star envelopes. In…
Non-Gaussian conductance noise in disordered electronic systems due to a non-linear mechanism
V. Orlyanchik, V. I. Kozub, Z. Ovadyahu
We present results of conductance-noise experiments on disordered films of crystalline indium oxide with lateral dimensions 2microns to 1mm. The power-spectrum of the noise has the…

To describe the interaction of the two level systems (TLSs) of an amorphous solid with arbitrary strain fields, we introduce a generalization of the standard interaction Hamiltonia…
