Free-energy distribution functions for the randomly forced directed polymer
V. S. Dotsenko, V. B. Geshkenbein, D. A. Gorokhov +1
We study the -dimensional random directed polymer problem, i.e., an elastic string subject to a Gaussian random potential and confined within a plane. We mainl…
Comment on ``Vortices with Fractional Flux in Two-Gap Superconductors and Extended Faddeev Model'', ``Phase Diagram of Planar U(1)xU(1) Superconductor'' and "Flux Noise in MgB2 Thin Films"
D. A. Gorokhov
I show that recent theoretical [1,2] and experimental [3] claims about the possibility of the Berezinskii-Kosterlitz-Thouless (BKT) transition of ``fractional vortices'' in thin fi…
Mesoscopic bound on anisotropy in itinerant ferromagnets
Piet W. Brouwer, Denis A. Gorokhov
We calculate the anisotropy energy of a single-domain ferromagnetic particle in which the only source of anisotropy is the presence of non-magnetic impurities. We find that such an…
Surface Superconductivity of Dirty Two-Band Superconductors: Applications to
Denis A. Gorokhov
The minimal magnetic field destroying superconductivity in the {\it bulk} of a superconductor is smaller than the magnetic field needed to destroy {\it surface} s…
Electron correlations in metal nanoparticles with spin-orbit scattering
Denis A. Gorokhov, Piet W. Brouwer
The combined effect of electron-electron interactions and spin-orbit scattering in metal nanoparticles can be studied by measuring splitting of electron levels in magnetic field ($…
Ultrasharp Crossover from Quantum to Classical Decay in a Quantum Dot Flanked by a Double-Barrier Tunneling Structure
Denis A. Gorokhov, Rava A. da Silveira
The decay of metastable states is dominated by quantum tunneling at low temperatures and by thermal activation at high temperatures. The escape rate of a particle out of a square w…
