Compactly Supported Spherically Symmetric Potentials Are Uniquely Determined by the Phase Shift of S-wave
نویسنده
چکیده
It is proved that a compactly supported (or decaying faster than any exponential) spherically symmetric potential is uniquely determined by the phase shift δ(k) known for all k ∈ (a, b), 0 ≤ a < b < ∞. Here the phase shift δ(k) corresponds to the s-wave. No information about bound states energies and normalizing constants is assumed known

Piecewise-constant Positive Potentials with Practically the Same Fixed-energy Phase Shifts
It has recently been shown that spherically symmetric potentials of finite range are uniquely determined by the part of their phase shifts at a fixed energy level k > 0. However, numerical experiments show that two quite different potentials can produce almost identical phase shifts. It has been guessed by physicists that such examples are possible only for ”less physical” oscillating and chang...

It is proved that the phase shift δ0(k) known for all k > 0, determines a real-valued locally integrable spherically symmetric potential q(x), |q(x)| ≤ C exp(−c|x|γ), γ > 1, where γ is a fixed number, c and C are positive constants. A procedure for finding the unknown potential from the above phase shift is proposed, an iterative process for finding the potential from the above data is describe...
متن کاملStability of Spherically Symmetric Wave Maps
We study Wave Maps from R2+1 to the hyperbolic plane H2 with smooth compactly supported initial data which are close to smooth spherically symmetric initial data with respect to some H1+μ, μ > 0. We show that such Wave Maps don’t develop singularities in finite time and stay close to the Wave Map extending the spherically symmetric data(whose existence is ensured by a theorem of Christodoulou-T...
متن کاملRelativistic Corrections for the Scattering Matrix for Spherically Symmetric Potentials
We use the framework for the nonrelativistic limit of scattering theory for abstract Dirac operators developed in [5] to prove holomorphy of the scattering matrix at fixed energy with respect to c−2 for Dirac operators with spherically symmetric potentials. Relativistic corrections of order c−2 to the nonrelativistic limit partial wave scattering matrix are explicitly determined.
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
