Unversality of decoherence in the macroworld
Walter T. Strunz, Fritz Haake, Daniel Braun
We consider environment induced decoherence of quantum superpositions to mixtures in the limit in which that process is much faster than any competing one generated by the Hamilton…

Zero temperature correlations in trapped Bose-Einstein condensates
Walter T. Strunz
We introduce a family of correlated trial wave functions for the -particle ground state of an interacting Bose gas in a harmonic trap. For large , the correlations lead to a…
