Seminar topic: “Low-energy asymptotics of the phases of two-dimensional scattering of a quantum particle by a central long-range potential”
Speaker: V.V. Pupyshev
Abstract:
We study the two-dimensional scattering of a quantum particle in the field of a central long-range potential decaying in the limit of large distance r as a power-law function r−β with β > 2. We find explicit low-energy asymptotic forms of all partial scattering phases of such a particle.
