Seminar topic: “Two-dimensional low-energy scattering of a quantum particle in the combined field of the Coulomb and power potentials”
>Speaker: Vasily V. Pupyshev
Abstract:
We study the two-dimensional scattering of a quantum particle by the force center
acting on it though a superposition of the Coulomb and power potential V0 r−β with the exponent β ∈ (1,2). For this scattering, we found explicit low-energy asymptotics of all partial phase shifts and amplitudes.
