Description
I consider the quantum sensing of gravity and rotation fields
using spatially localized probes (trapped systems) of ultracold quantum gases of interacting atoms or molecules.
It is shown that to achieve an accurate statement on the optimality
of a given measurement protocol, it is mandatory to go beyond the standard quantum optics paradigm of describing the system by a Hamiltonian containing (powers of) Fock space operators with constant coefficients, which is leading e.g. to spin models. Instead, the evolution needs to be described fully self-consistently, with both Fock state occupation probabilities of the system modes
and the shape of the associated orbitals (single-particle wave functions) changing in an inter-dependent way dynamically.
