Description of Fischer Clusters Formation in Supercooled Liquids Within Framework of Continual Theory of Defects
M. G. Vasin, V. I. Lad'yanov
Liquid is represented as complicated system of disclinations according to defect description of liquids and glasses. The expressions for the linear disclination field of an arbitra…
Equation of state for partially ionized carbon at high temperatures
A. Y. Potekhin, G. Massacrier, G. Chabrier
Equation of state for partially ionized carbon at temperatures T > ~ 10^5 K is calculated in a wide range of densities, using the method of free energy minimization in the framewor…
Multi-Wavelength Studies of the Optically Dark Gamma-Ray Burst 001025A
K. Pedersen, K. Hurley, J. Hjorth +18
We identify the fading X-ray afterglow of GRB 001025A from XMM-Newton observations obtained 1.9-2.3 days, 2 years, and 2.5 years after the burst. The non-detection of an optical co…
The magnetic structure of neutron stars and their surface-to-core temperature relation
A. Y. Potekhin, V. Urpin, G. Chabrier
We study the relation between the mean effective surface temperature T_s and the internal temperature T_b for magnetic neutron stars, assuming that the magnetic field near the surf…
Size of flux jumps in superconducting films
D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +2
Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a…
Fluctuations of the Fermi condensate in ideal gases
Dragos-Victor Anghel, Oleg Fefelov, Y. M. Galperin
We calculate numerically and analytically the fluctuations of the fermionic condensate and of the number of particles above the condensate for systems of constant density of states…
