Purely imaginary eigenvalues of Zakharov-Shabat systems
(American Physical Society, 2002-03)
Zakharov-Shabat systems with single-hump and real, but not necessarily symmetric, potentials are shown to have purely imaginary eigenvalues only. Coupled with examples of double-hump potentials with nonimaginary eigenvalues, ...
Nucleation of superconductivity in finite anisotropic superconductors and the evolution of surface superconductivity toward the bulk mixed state
(American Physical Society, 2002-02-14)
In anisotropic superconductors having an arbitrary orientation of the sample surface relative to the crystal principal axes, the surface critical field H-c3 is less than 1.695H(c2) unless the field is situated along one ...
Numerical simulation of drop retraction after a strain jump
(American Physical Society, 2009-04)
A spherical drop of one liquid suspended in another is subjected to an instantaneous initial shear. We simulate the retraction of the drop to its spherical equilibrium and compare the results with recent experiments. In ...
Stochastic dynamics of Ginzburg-Landau vortices in superconductors
(American Physical Society, 2001-08-01)
Thermal fluctuations and randomly distributed defects in superconductors are modeled by stochastic variants of the time-dependent Ginzburg-Landau equations. Numerical simulations are used to compare the effects of additive ...
