Research Highlights:

Our recent studies concern a "resistor network" theory for the energy absorption of weakly chaotic systems. Applications: the heating of cold atoms in vibrating traps; the conductance of closed mesoscopic rings. Another major line of study concerns quantum stirring of particles in such (closed) devices by means of "quantum pumping". The links below contain one-paragraph descriptions of some highlights.
