Query: Phase-space representation of diffraction in time: Analytic results   Diffraction in time manifests itself as the appearance of probability-density
fringes when a matter wave passes through an opaque screen with abrupt temporal
variations of transmission properties. Here we analytically describe the
phase-space structure of diffraction-in-time fringes for a class of smooth time
gratings. More precisely, we obtain an analytic expression for the Husimi
distribution representing the state of the system in the case of time gratings
comprising a succession of Lorentzian-like slits. In particular, for a
double-slit scenario, we derive a simple and intuitive expression that
accurately captures the position of interference fringes in phase space.
