The science paper is now published in Science 333, 196 (2011):

Some results from my recent sabbatical in Amsterdam are accepted for publication in Science magazine!

Our paper on Loschmidt cooling, or time-reversal of a quantum system in a classically chaotic regime, has been published in Physical Review E. See a preprint on the archive.

Now we finally have a new web page, which will grow some content as time goes on. The starting point should be the welcome page.

At the moment, experiments are underway to investigate higher order quantum resonances in the atom optics implementation of the delta-kicked rotor. Things are working well, despite the building renovations and our recent bout of problems.
