                Optimal Quantum Control of
        Bose-Einstein condensates in magnetic microtraps


Confined atom interferometers using Bose-Einstein condensates (BECs) offer 
new prospects for matter wave interferometry and precision measurements. 
In this talk, I theoretically investigate the limitations of such atom 
interferometers and explore the possibility to improve the performance by 
means of optimal control theory (OCT). Within the framework of the 
Gross-Pitaevskii equation, simulation of splitting and trapping of the 
condensate are presented. Atom number squeezing and the resulting phase 
diffusion are investigated within the framework of a generic two-mode 
model and the multi-configurational Hartree method for Bosons (MCTDHB). 
Our results show that optimized control strategies allow for efficient 
condensate trapping and number squeezing on short time scales.
