Hello everyone,
This Wednesday, we will have a surprise field trip to the chemistry
building (HCI E 2 - I have no idea where that is either) for a
non-group-meeting group seminar, with a talk given by Sandra Rankovic.
Your favorite seminar organizer, who has no doubt been sorely missed in
the past few months,
--Fred

Title: Two-particle billiard systems
Date/Time/Place: Wednesday, Dec 7, 15.00, HCI E 2
Abstract:
Dynamical billiards represent the Hamiltonian idealization of the
billiard game, and they appear as natural models in problems of optics,
acoustics and classical mechanics. They are defined by a connected
region in 2D space with the piecewise smooth boundary, and the point
particles of non-zero radius confined to move inside this region. The
particles move freely until encountering the boundary or the other
particle, when they reflect specularly. We investigate the two-particle
circular billiard and its chaotic properties, and attempt approximating
it with a randomly perturbed one-particle billiard in the limit of small
particle radius.
