Title: Chaotic dephasing in a double-slit scattering experiment

Time: Mon, Jun 14, 2010, 4:15pm

Place: Building 28, Room 2.100

Abstract:

We design a computational experiment in which a quantum particle tunnels into a billiard of variable shape and scatters out of it through a double-slit opening. The interference patterns produced by the scattered probability currents are investigated in relation to the billiard's geometry, which is connected to its classical integrability.

In the integrable case most experiment outcomes are consistent with the constructive interference occurring in the usual double-slit experiment. In contrast, non-integrable billiards typically display asymmetric interference patterns of smaller visibility. Our findings indicate an intrinsic connection between the classical integrability and the quantum dephasing.
