Abstract:
We assess the difficulties in creating a provably coherent quantum state
of a relative motion of two bosonic solitons using Gross-Pitaevskii breathers.
The scheme for creating such state---a four-fold quench of the interactions applied
to a bosonic soliton---is not new. However, an experimental proof of a macroscopic coherence
is difficult. Our proposal is to suggest a protocol where variances of the
relative distance and the relative momentum are experimentally accessible: then
whenever the product of the two gets close to the Heisenberg uncertainty limit, such state
can be declared to be coherent. We present an extensive numerical study on the subject.

The projects are run in a tight collaboration with
Randall Hulet’s experimental group at Rice University.
