    "abstract": "Mesoscopic physics deals with three fundamental issues: quantum coherence,\nfluctuations and correlations. Here we analyze these issues for atom optics,\nusing a simplified model of an assembly of atoms (or detectors, which are\nparticles with some internal degree of freedom) moving in arbitrary\ntrajectories in a quantum field. Employing the influence functional formalism,\nwe study the self-consistent effect of the field on the atoms, and their mutual\ninteractions via coupling to the field. We derive the coupled Langevin\nequations for the atom assemblage and analyze the relation of dissipative\ndynamics of the atoms with the correlation and fluctuations of the quantum\nfield. This provides a useful theoretical framework for analysing the coherent\nproperties of atom-field systems.",
