Interference and entanglement of two massive particles — •Álvaro Tejero Cantero and Klaus Hornberger — Arnold Sommerfeld Center for Theoretical Physics, LMU München

Non-classical correlations in the motional state of two massive, spatially separated particles can be characterised operationally in a measurement setup which probes emission-time entanglement. By combining the time-dependent scattering approach with the Weyl phase-space representation of quantum mechanics, we provide a framework in which the dynamics of the measurement process can be modelled analytically. The formalism is applied to input states which are based on Gaussians, allowing to obtain the two-particle detection probabilities in closed form. The results display the full range of interference phenomena and their interplay with the dispersive dynamics.
