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…
Magnetic Hydrogen Atmosphere Models and the Neutron Star RX J1856.5-3754
Wynn C. G. Ho, David L. Kaplan, Philip Chang +2
RX J1856.5-3754 is one of the brightest nearby isolated neutron stars, and considerable observational resources have been devoted to it. However, current models are unable to satis…
Non-Gaussian dephasing in flux qubits due to 1/f-noise
Y. M. Galperin, B. L. Altshuler, J. Bergli +2
Recent experiments by F. Yoshihara et al. [Phys. Rev. Lett. 97, 167001 (2006)] and by K. Kakuyanagi et al. (cond-mat/0609564) provided information on decoherence of the echo signal…
Fine structure of exciton excited levels in a quantum dot with a magnetic ion
M. M. Glazov, E. L. Ivchenko, L. Besombes +3
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…
