Dispersive Lineshape Theory
YounJoon Jung, Eli Barkai, Robert J. Silbey
Motivated by recent experiments we consider a stochastic lineshape theory for the case when the underlying process obeys power-law statistics, based on a generalized Anderson-Kubo…

Fractional Kramers Equation
E. Barkai, R. Silbey
We introduce a fractional Kramers equation for a particle interacting with a thermal heat bath and external non-linear force field. For the force free case the velocity damping fol…

Transforming Gaussian diffusion into fractional a generalized law of large numbers approach
E. Barkai
The fractional Fokker-Planck equation (FFPE) [R. Metzler, E. Barkai, J. Klafter, Phys. Rev. Lett., 82, 3563 (1999)] describes an anomalous sub diffusive behavior of a particle in a…
