DESCRIPTION:Speaker: Barbara Roos\nhosted by Robert Seiringer\nAbstract: We
  study two interacting quantum particles forming a bound state in d-dimens
 ional free space\, and constrain the particles to half-space in k directio
 ns\, 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 kine
 tic energy\, has only finitely many eigenvalues below the essential spectr
 um. 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 co
 llaboration with Robert Seiringer.
