Dimensions: Inverse Scattering Analysis

چکیده
Formation of fermion bag solitons is an important paradigm in the theory of hadron structure. We report here on our non-perturbative analysis of this phenomenon in the 1+1 dimensional massive Gross-Neveu model, in the large N limit. Our main result is that the extremal static bag configurations are reflectionless, as in the massless Gross-Neveu model. Explicit formulas for the profiles and masses of these solitons are presented. We also present a particular type of self-consistent reflectionless solitons which arise in the massive Nambu-Jona-Lasinio models, in the large-N limit.

Applications of Clifford Analysis to Inverse Scattering for the Linear Hierarchy in Several Space Dimensions
The Inverse Scattering Transform (IST) is a nonlinear analog of the Fourier transform which has been used to solve certain nonlinear evolution equations in the same way that the Fourier transform can be used to solve linear partial diierential evolution equations. The current understanding of the IST is based on the complex inhomogeneous Cauchy-Riemann equation. This works ne in one space dimen...
متن کاملFactorization Method for Electromagnetic Inverse Scattering from Biperiodic Structures
We investigate the Factorization method as an analytical as well as a numerical tool to solve inverse electromagnetic wave scattering problems from penetrable biperiodic structures in three dimensions. This method constructs a simple criterion whether a given point in space lies inside or outside the penetrable biperiodic structure, yielding a fast imaging algorithm. The required data consists ...
متن کاملAn effectivization of the global reconstruction in the Gel'fand-Calderon inverse problem in three dimensions
Abstract. By developing the ∂̄-approach to global ”inverse scattering” at zero energy we give a principal effectivization of the global reconstruction method for the Gel’fandCalderon inverse boundary value problem in three dimensions. This work goes back to results published by the author in 1987, 1988 and proceeds from recent progress in the ∂̄-approach to inverse scattering in 3D published by t...
متن کاملSea Surfaces Scattering by Multi-Order Small-Slope Approximation: a Monte-Carlo and Analytical Comparison
L-band electromagnetic scattering from two-dimensional random rough sea surfaces are calculated by first- and second-order Small-Slope Approximation (SSA1, 2) methods. Both analytical and numerical computations are utilized to calculate incoherent normalized radar cross-section (NRCS) in mono- and bi-static cases. For evaluating inverse Fourier transform, inverse fast Fourier transform (IFFT) i...
متن کاملInverse scattering problem for the Impulsive Schrodinger equation with a polynomial spectral dependence in the potential
In the present work, under some di¤erentiability conditions on the potential functions , we rst reduce the inverse scattering problem (ISP) for the polynomial pencil of the Scroedinger equation to the corresponding ISP for the generalized matrix Scrödinger equation . Then ISP will be solved in analogy of the Marchenko method. We aim to establish an e¤ective algorithm for uniquely reconstructin...
متن کاملA Point-source Method for Inverse Acoustic and Electromagnetic Obstacle Scattering Problems
We present the mathematical foundation for a point-source method to solve some inverse acoustic and electromagnetic obstacle scattering problems in three dimensions. We investigate the inverse acoustic scattering problem by a sound-soft and a sound-hard scatterer and the inverse electromagnetic scattering problem by a perfect conductor. Two independent approaches to the method are presented whi...
