Two-Particle Bound States at Interfaces and Corners

MATHPHYS ANALYSIS SEMINAR

Date: May 27, 2021 | 4:15 pm – 5:15 pm
Speaker: Barbara Roos, IST Austria
Location: Online via Zoom

We study two interacting quantum particles forming a bound state in d-dimensional free space, and constrain the particles to half-space in k directions, with Neumann boundary conditions. First, we show that the particles stick to the corner where all boundary planes intersect. Second, we prove that the resulting Hamiltonian, after removing the free part of the kinetic energy, has only finitely many eigenvalues below the essential spectrum. This generalizes the work of Egger, Kerner and Pankrashkin (J. Spectr. Theory 10(4):1413–1444, 2020) to dimensions d>1 and was obtained in collaboration with Robert Seiringer.
