Learning interactions via hierarchical group-lasso regularization
hierarchical interaction computer intensive regression logistic
2015/8/21
We introduce a method for learning pairwise interactions in a linear regression or logistic regression model in a manner that satisfies strong hierarchy: whenever an interaction is estimated to be non...
Dark-in-bright solitons in Bose-Einstein condensates with attractive interactions
Condensate the scattering length in the form of a dark soliton optical lattice parabolic magnetic trap discrete nonlinear schrodinger equation
2014/12/29
We demonstrate a possibility to generate localized states in effectively one-dimensional Bose-Einstein condensates with a negative scattering length in the form of a dark soliton in the presence of an...
Solitary wave interactions in dispersive equations using Manton’s approach

2014/12/29
We generalize the approach first proposed by Manton [Nucl. Phys. B 150, 397 (1979)] to compute solitary wave interactions in translationally invariant, dispersive equations that support such localized...
Asymptotic calculation of discrete non-linear wave interactions

2014/12/25
We illustrate how to compute asymptotic interactions between discrete solitary waves of dispersive equations, using the approach proposed by Manton [N.S. Manton, Nucl. Phys. B 150 (1979) 397]. We also...
Non-nearest-neighbor interactions in nonlinear dynamical lattices
Discrete nonlinear schrodinger equation the nonlinear dynamic systematic zero coupling
2014/12/24
We revisit the theme of non-nearest-neighbor interactions in nonlinear dynamical lattices, in the prototypical setting of the discrete nonlinear Schrödinger equation. Our approach offers a system...
Solitons in quasi-one-dimensional Bose-Einstein condensates with competing dipolar and local interactions
Signs of one-dimensional bright soliton on the contrary free space optical lattice
2014/12/24
We study families of one-dimensional matter-wave bright solitons supported by the competition of contact and dipole-dipole (DD) interactions of opposite signs. Soliton families are found, and their st...

2014/12/24
We consider the interplay of linear double-well-potential (DWP) structures and nonlinear longrange interactions of different types, motivated by applications to nonlinear optics and matter waves. We f...
COARSE-GRAINING SCHEMES FOR STOCHASTIC LATTICE SYSTEMS WITH SHORT AND LONG-RANGE INTERACTIONS
Coarse-grained plan particle microscopic model dimensional lattice the renormalization group
2014/12/24
We develop coarse-graining schemes for stochastic many-particle microscopic models with competing short- and long-range interactions on a d-dimensional lattice. We focus on the coarse-graining of equi...
