Structure of an Elastic Lattice Pinned by Hopping Defects
The translational order in a three-dimensional lattice pinned by hopping defects is studied. It is suggested that the equilibrium state of the lattice crosses from a glass to a crystal on the rate of hopping. It is argued that such a transition may exist in flux lattices of hightemperature superconductors due to the hopping of oxygen. PACS. 74.60.Ge Flux pinning, flux creep, and flux lattice dy...
متن کاملMajorana fermions in pinned vortices
Exploiting the peculiar properties of proximity-induced superconductivity on the surface of a topological insulator, we propose a device, which allows the creation of a Majorana fermion inside the core of a pinned Abrikosov vortex. The relevant Bogolyubov-de Gennes equations are studied analytically. We demonstrate that in this system the zero-energy Majorana-fermion state is separated by a lar...
متن کاملMultiple Ginzburg-landau Vortices Pinned by Randomly Distributed Small Holes
In this work a minimization problem for the magnetic Ginzburg-Landau functional in a circular domain with randomly distributed small holes is considered. We develop a new analytical approach for solving a non-standard boundary value problem for the magnetic field presented as a function of the n-tuple of degrees of vortices pinned by the n holes. The key feature of this approach is that the sol...
متن کاملAdler synchronization of spatial laser solitons pinned by defects.
Defects due to growth fluctuations in broad-area semiconductor lasers induce pinning and frequency shifts of spatial laser solitons. The effects of defects on the interaction of two solitons are considered in lasers with frequency-selective feedback both theoretically and experimentally. We demonstrate frequency and phase synchronization of paired laser solitons as their detuning is varied. In ...
متن کاملEects of Columnar and Point Defects on Magnetic Hysteresis Curves Produced by Three-dimensional Vortices in Layered Superconductors
Using parallel three-dimensional molecular dynamics simulations of line-like coupled pancake vortices, we consider the eect of inter-layer coupling strength and pinning correlation on the magnetization curves of anisotropic super-conductors. Columnar pins produce the largest critical current and are insensitive to layer interaction strength. Point pins are increasingly eective at pinning the ...
