Interior-Boundary Conditions for Many-Body Dirac Operators and Codimension-1 Boundaries
Julian Schmidt, Stefan Teufel, Roderich Tumulka
We are dealing with boundary conditions for Dirac-type operators, i.e., first order differential operators with matrix-valued coefficients, including in particular physical many-bo…

Derivation of the 1d Gross-Pitaevskii equation from the 3d quantum many-body dynamics of strongly confined bosons
Lea Boßmann, Stefan Teufel
We consider the dynamics of interacting bosons initially forming a Bose-Einstein condensate. Due to an external trapping potential, the bosons are strongly confined in two dime…
