Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Measurements with a one-electron quantum cyclotron determine the electron magnetic
moment, given by g/2= 1.001 159 652 180 73 (28)[0.28 ppt], and the fine structure constant …

We study switching between period-two states of an underdamped quantum oscillator
modulated at nearly twice its natural frequency. For all temperatures and parameter values …

Stochastic switching between the two bistable states of a strongly driven mechanical
resonator enables detection of weak signals based on probability distributions, in a manner …

We study noise induced switching in systems far from equilibrium by using an underdamped
micromechanical torsional oscillator driven into the nonlinear regime. Within a certain range …

The physics of critical phenomena in a many-body system far from thermal equilibrium is an
interesting and important issue to be addressed both experimentally and theoretically. The …

The cantilever is a prototype of a highly compliant mechanical system and has an
instrumental role in nanotechnology, enabling surface microscopy, and ultrasensitive force …

We consider decay of metastable states of forced vibrations of a quantum oscillator close to
the bifurcation points where the states disappear. Decay occurs via quantum activation over …

We demonstrate that the paths followed by a system in fluctuation-activated switching form a
narrow tube in phase space. A theory of the path distribution is developed and its direct …

We explore fluctuation-induced switching in parametrically driven micromechanical torsional
oscillators. The oscillators possess one, two, or three stable attractors depending on the …
