Variational method to study vortex matter in mesoscopic superconductors
W. V. Pogosov, A. L. Rakhmanov, E. A. Shapoval
A simple variational model is proposed to analyze the superconducting state in long cylindrical type-II superconductor placed in the external magnetic field. In the framework of th…
First integrals of Ginzburg-Landau equations and stability criteria for vortex-free state in unconventional superconductors
K. I. Kugel, W. V. Pogosov, A. L. Rakhmanov
The first integrals of the Ginzburg-Landau equations for a vortex-free state of superconductors with different mixed symmetries of the order parameter are found. The general bounda…
Approximate Ginzburg-Landau solution for the regular flux-line lattice. Circular cell method
W. V. Pogosov, K. I. Kugel, A. L. Rakhmanov +1
A variational model is proposed to describe the magnetic properties of type-II superconductors in the entire field range between and for any values of the Ginzbur…
Resistivity and 1/f Noise in Non-Metallic Phase Separated Manganites
A. L. Rakhmanov, K. I. Kugel, Ya. M. Blanter +1
A simple model is proposed to calculate resistivity, magnetoresistance, and noise spectrum in non-metallic phase-separated manganites containing small metallic droplets (magnetic p…
