Experimental and numerical investigation of the reflection coefficient and the distributions of Wigner's reaction matrix for irregular graphs with absorption

of the distribution of the reflection coefficient P(R) and the distributions of the imaginary P(v) and the real P(u) parts of the Wigner reaction K matrix for irregular fully connected was modeled by optical potentials. The distrib...

Spectral Theory for Schrodinger Operators with delta-Interactions Supported on Curves in R-3

The main objective of this paper is to systematically develop a spectral and scattering theory for self-adjoint Schrodinger operators with delta-interactions supported on closed curves in R-3. We provide bounds for the number of neg...

Efficient solution of scattering equations by combination of R-matrix and Lanczos methods

We propose a fast and economical computational method for solving scattering Lippmann-Schwinger integral equation. Our approach benefits from the accurate construction of the Green's function based on the R-matrix theory co...

Astrophysical S factor for the N-15(p,gamma)O-16 reaction

The R-matrix approach has proved to be very useful in extrapolating the astrophysical factor down to astrophysically relevant energies, since the majority of measurements are not available in this region. However, such an approach h...

Validity of the Born-Oppenheimer approximation in the indirect-dissociative-recombination process

. The two-dimensional R matrix can be constructed simultaneously on the electronic and electron-molecule collisions. These are the eigenchannel R-matrix form, inversion over the poles of the symmetrized Hamiltonian...

Approximate treatment of noncommutative curvature in quartic matrix model

We study a Hermitian matrix model with the standard quartic potential amended by a tr(RΦ2) term for fixed external matrix R. This is motivated by a curvature term — a renormalizable noncommutative field theory. The...
