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...

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...
Modelling interactions in high-dimensional data with Backtracking
Backtracking interactions Lasso parallel computing path algorithm.
2012/9/17
We study the problem of high-dimensional regression when there may be interacting vari-ables. We introduce a new idea called Backtracking, that can be incorporated into many existing high-dimensional ...
A proof of Bell's inequality in quantum mechanics using causal interactions
Interactions interference local reality quantum physics
2012/9/19
We give a simple proof of Bell’s inequality in quantum mechanics which, in conjunction with experiments, demonstrates that the local hidden variables assumption is false. The proof sheds light on rela...
Fast Inference of Interactions in Assemblies of Stochastic Integrate-and-Fire Neurons from Spike Recordings

2011/3/24
We present two Bayesian procedures to infer the interactions and external currents in an assembly of stochastic integrate-and-fire neurons from the recording of their spiking activity. The first proce...
