Nonlinear Phase Dynamics in a Driven Bosonic Josephson Junction
... With adjustable parameters, the BHH can also realize an atom interferometer, in which the bias, E, generates a phase shift that can be measured by atom-number counting. The interaction term allows for the creation of nonclassical input states, but also generates undesired phase-diffusion noise. Atom ...

The Emperor`s New Mind by Roger Penrose

If relativity theory holds 'all the way down', there must be a singularity in every black hole where the laws of physics no longer apply. Even this achievement has b ...
