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 -…
