Abstract: We present a systematic approach to determine all relativistic phases up to $\mathcal{O}(c^{-2})$ in light-pulse atom interferometers in weakly curved spacetime that are based on elastic scattering, namely Bragg diffraction and Bloch oscillations. Our analysis is derived from first principles using the parameterized post-Newtonian formalism. In the treatment developed here, we derive algebraic expressions for relativistic phases for arbitrary interferometer geometries in an automated manner. As case studies, we consider symmetric and antisymmetric Ramsey-Bord\'e interferometers, as well as a symmetric double diffraction interferometer with baseline lengths of 10 m and 100 m. We compare our results to previous calculations conducted for a Mach-Zehnder interferometer.

Realizing a spatially correlated lattice interferometer [8.81055904289318]
Atom interferometers provide a powerful tool for measuring physical constants and testifying fundamental physics with unprecedented precision. Here, we report on realizing a Ramsey-Bord'e interferometer of coherent matter waves dressed by a moving optical lattice in the gravity direction. Our findings agree well with theoretical simulations, paving the way for high-precision interferometry with ultracold atoms.

Light-Pulse Atom Interferometric Test of Continuous Spontaneous Localization [0.0]
We derive an exponential loss of the contrast that scales linearly with the interferometer time $T$ if both interferometer arms are spatially separated. We compare our theoretical results with measurements from a cold rubidium atom interferometer based on counter-propagating two-photon transitions with separation pulse times up to $T$ = 260 ms.

Two-colour spectrally multimode integrated SU(1,1) interferometer [77.34726150561087]
We develop and investigate an integrated multimode two-colour SU (1,1) interferometer that operates in a supersensitive mode. By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*104$ photons are generated.

Quantum asymmetry and noisy multi-mode interferometry [55.41644538483948]
Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator. We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.
