Motion and Homogenization of Vortices in Anisotropic Type II Superconductors
The motion of vortices in an anisotropic superconductor is considered. For a system of well-separated vortices, each vortex is found to obey a law of motion analogous to the local induction approximation, in which velocity of the vortex depends upon the local curvature and orientation. A system of closely packed vortices is then considered, and a mean field model is formulated in which the indi...
متن کاملAnisotropic impurities in anisotropic superconductors
Physical properties of anisotropic superconductors like the critical temperature and others depend sensitively on the electron mean free path. The sensitivity to impurity scattering and the resulting anomalies are considered a characteristic feature of strongly anisotropic pairing. These anomalies are usually analyzed in terms of s-wave impurity scattering which leads to universal pair breaking...
متن کاملWaardenburg syndrome: clinical differentiation between types I and II.
Here we present the results of a study performed on 59 patients affected by Waardenburg syndrome (WS), 30 with the I variant, 21 having the type II, and 8 of them being isolated cases without telecanthus. These patients belong to 37 families; the main contributions and conclusions are based on the detailed study of 25 of these families, examined using standard procedures. All patients were exam...
متن کاملComment on vortex liquid crystal in anisotropic type II superconductors.
Comment on " Vortex Liquid Crystal in Anisotropic Type II Superconductors " Recently Carlson et al. [1] tried to compose the H − T phase diagram of anisotropic superconductors based on the Lindemann criterion for melting of flux-line lattice. It is worthy to notice that the issue itself is interesting. However, their conclusion on the existence of a smectic vortex phase is unphysical for the fo...
متن کاملVortex liquid crystals in anisotropic type II superconductors.
In an isotropic type II superconductor in a moderate magnetic field, the transition to the normal state occurs by vortex lattice melting. In certain anisotropic cases, the vortices acquire elongated cross sections and interactions. Systems of anisotropic, interacting constituents generally exhibit liquid crystalline phases. We examine the possibility of a two step melting in homogeneous type II...
