Positional order of the pinned Abrikosov flux - line lattice in samples of finite thickness

We study translational correlations of the vortex center of mass positions of the Abrikosov flux-line lattice in superconducting samples of finite thickness L (along the direction of flux-lines). The Larkin correlation lengths for the center of mass mode of the flux lines in the presence of point and correlated disorder are computed, and we find that in the case of point disorder the average (i...

COMPUTATIONAL ENUMERATION OF POINT DEFECT CLUSTERS IN DOUBLE- LATTICE CRYSTALS

The cluster representation matrices have already been successfully used to enumerate close-packed vacancy clusters in all single-lattice crystals [I, 2]. Point defect clusters in double-lattice crystals may have identical geometry but are distinct due to unique atomic postions enclosing them. The method of representation matrices is extended to make it applicable to represent and enumerate ...

Lattice Green’s function for crystals containing a planar interface

Flexible boundary condition methods couple an isolated defect to a harmonically responding medium through the bulk lattice Green’s function; in the case of an interface, interfacial lattice Green’s functions. We present a method to compute the lattice Green’s function for a planar interface with arbitrary atomic interactions suited for the study of line defect/interface interactions. The interf...

The lattice SU (2) confining string as an Abrikosov vortex

Numerical data [10] for the SU(2) confining string in the maximal abelian projection are analysed. The distribution of the electric flux and monopole currents are perfectly described by the classical equations of motion for the dual Abelian Higgs model. The mass of the vector boson is equal to the mass of the monopole (Higgs particle) within numerical errors. The classical energy per unit lengt...
