Optimizing number squeezing when splitting a mesoscopic condensate
TL;DR: In this article, the authors apply optimal control theory to a mesoscopic Bose-Einstein condensate to identify a form of the splitting ramp, which drastically outperforms the adiabatic splitting.
Atom interferometry with trapped Bose?Einstein condensates: impact of atom?atom interactions
TL;DR: In this paper, the nonlinearities from atom?atom interactions, on the one hand, allow us to efficiently produce squeezed states for enhanced readout and on the other hand, result in phase diffusion that limits the phase accumulation time.
Vibrational state inversion of a Bose–Einstein condensate: optimal control and state tomography
Robert Bücker,Tarik Berrada,Sandrine van Frank,Jean-François Schaff,Thorsten Schumm,Jörg Schmiedmayer,Georg Jäger,Julian Grond,Ulrich Hohenester +8 more
TL;DR: In this paper, the authors present theoretical and experimental results on high-fidelity transfer of a trapped Bose-Einstein condensate into its first vibrationally excited eigenstate.

Mach-Zehnder interferometry with interacting trapped Bose-Einstein condensates
TL;DR: In this article, the authors theoretically analyze a Mach-Zehnder interferometer with trapped condensates and find that it is surprisingly stable against the nonlinearity induced by interparticle interactions.
