Generalized gravity-gradient mitigation scheme

no code implementations3 Feb 2021 Christian Ufrecht

A major challenge in high-precision light-pulse atom interferometric experiments such as in tests of the weak equivalence principle is the uncontrollable dependency of the phase on initial velocity and position of the atoms in the presence of inhomogeneous gravitational fields.
