The NLS limit for bosons in a quantum waveguide
Johannes von Keler, Stefan Teufel
We consider a system of bosons confined to a thin waveguide, i.e.\ to a region of space within an -tube around a curve in . We show that when taking…

Non-adiabatic transitions in a massless scalar field
Johannes von Keler, Stefan Teufel
We consider the dynamics of a massless scalar field with time-dependent sources in the adiabatic limit. This is an example of an adiabatic problem without spectral gap. The main go…
