Quantum waveguides with magnetic fields
Stefan Haag, Jonas Lampart, Stefan Teufel
We study generalised quantum waveguides in the presence of moderate and strong external magnetic fields. Applying recent results on the adiabatic limit of the connection Laplacian…

The adiabatic limit of the connection Laplacian
Stefan Haag, Jonas Lampart
We study the behaviour of Laplace-type operators H on a complex vector bundle E M in the adiabatic limit of the base space. This space is a fibre bundle M $\rightarro…

Particle Creation at a Point Source by Means of Interior-Boundary Conditions
Julian Schmidt, Jonas Lampart, Stefan Teufel +1
We consider a way of defining quantum Hamiltonians involving particle creation and annihilation based on an interior-boundary condition (IBC) on the wave function, where the wave f…
