61. Looping and direct transit in Brownian particle escape from force-biased and entropic traps

oral

Recent experiments with single biological nanopores, as well as single-molecule fluorescence spectroscopy and pulling studies of protein and nucleic acid folding raised a number of questions that stimulated theoretical and computational studies of the barrier crossing dynamics. We focus on trajectories of Brownian particles that escape from traps either in the presence of an external force or...

111. Diffusive escape through a narrow opening: new insights into a classic problem

oral

In this talk I overview our recent results [1] on the mean first escape time T of a diffusive particle from a spherical (or a circular) domain enclosed by an impenetrable boundary containing a small escape window. Our settings differ from the classical narrow escape problem in two aspects : First, we introduce explicitly into the model long-range potential interactions of a particle with the...

40. Anomalous quantum diffusion of hydrogen atoms in proteins

Gerald Kneller (University of Orleans / CNRS)

oral

Gerald Kneller Centre de Biophysique Moléculaire CNRS/University of Orléans, France Quasielastic neutron scattering (QENS) from biomolecular systems, such as proteins, probes essentially the diffusive single particle dynamics of the hydrogen atoms. As far as the internal dynamics is considered, the motion of the hydrogen atoms exhibits both multiscale and quantum properties. Starting...
