Domain walls in the coupled Gross-Pitaevskii equations with the harmonic potential

Andres Contreras, Dmitry E. Pelinovsky, Valeriy Slastikov

We study the existence and variational characterization of steady states in a coupled system of Gross--Pitaevskii equations modeling two-component Bose-Einstein condensates with th…

Forward-backward approximation of evolution equations in finite and infinite horizon

Andres Contreras, Juan Peypouquet

This research is concerned with evolution equations and their forward-backward discretizations. Our first contribution is an estimation for the distance between iterates of sequenc…

Local minimizers with unbounded vorticity for the d Ginzburg-Landau functional

Andres Contreras, Robert L. Jerrard

A central focus of Ginzburg-Landau theory is the understanding and characterization of vortex configurations. On a bounded domain global minimizers, and…

Classifying Signals Under a Finite Abelian Group Action: The Finite Dimensional Setting

Jameson Cahill, Andres Contreras, Andres Contreras Hip

Let be a finite group acting on . We study the problem of identifyng the class in of a given signal: this encompasses several types of problems…

Complete set of translation invariant measurements with Lipschitz bounds

Jameson Cahill, Andres Contreras, Andres Contreras Hip

In image and audio signal classification, a major problem is to build stable representations that are invariant under rigid motions and, more generally, to small diffeomorphisms. T…

First critical field of highly anisotropic three-dimensional superconductors via a vortex density model

Andres Contreras, Guanying Peng

We analyze a mean field model for d anisotropic superconductors with a layered structure, in the presence of a strong magnetic field. The mean field model arises as the -…
