Coherent control of mesoscopic tunneling in a Bose-Einstein condensate
Christoph Weiss, Tharanga Jinasundera
For a weakly interacting Bose-Einstein condensate in a double well, an appropriate time-dependent modulation of the trapping potential counter-acts the "self-trapping" effects of t…
The first eigenvalue of the Laplacian, isoperimetric constants, and the Max Flow Min Cut Theorem
Daniel Grieser
We show how 'test' vector fields may be used to give lower bounds for the Cheeger constant of a Euclidean domain (or Riemannian manifold with boundary), and hence for the lowest ei…
Boundary cross theorem in dimension 1
Peter Pflug, Viet-Anh Nguyen
Let be two complex manifolds of dimension 1 which are countable at infinity, let be two open sets, let (resp. ) be a subset of $\partial D…
Runtime Reconfiguration of J2EE Applications
Jasminka Matevska-Meyer, Sascha Olliges, Wilhelm Hasselbring
Runtime reconfiguration considered as "applying required changes to a running system" plays an important role for providing high availability not only of safety- and mission-critic…
Periodic Field Emission from an Isolated Nano-Scale Electron Island
D. V. Scheible, C. Weiss, J. P. Kotthaus +1
We observe field emission from an isolated nano-machined gold island. The island is able to mechanically oscillate between two facing electrodes, which provide recharging and detec…
Ground-state energy and depletions for a dilute binary Bose gas
Andre Eckardt, Christoph Weiss, Martin Holthaus
When calculating the ground-state energy of a weakly interacting Bose gas with the help of the customary contact pseudopotential, one meets an artifical ultraviolet divergence whic…
