CMT Seminar - Mark Dykman, Michigan State University - Monday, April 6th - 11:30am, Smith Seminar Room (1080 PRB)

[Longbrake, Patricia]

Please join us on Monday, April 6th for the CMT Seminar presented by Mark Dykman, Michigan State University at 11:30am in the Smith Seminar Room (1080 PRB).

"Driven mesoscopic oscillators: a glimpse into quantum fluctuations far from equilibrium"

Abstract: Relaxation of periodically driven systems is accompanied by quantum noise. It leads to a finite width of the distribution over the states of the system even for T=0, the effect of quantum heating. It also leads to switching between metastable states via the mechanism of quantum activation that has no analog in equilibrium systems. These phenomena will be discussed using, as a model, a driven nonlinear oscillator. This model immediately refers to a large class of mesoscopic vibrational systems, from nanomechanical resonators to quantum cavity modes to Josephson junctions. The scaling behavior of the switching rates will be outlined and a comparison with the experiment will be made.

Please contact me if you are interested in meeting with Mark during his visit.

Thank you,
