Dynamics of a polymer in an active and viscoelastic bath.
We study the dynamics of an ideal polymer chain in a viscoelastic medium and in the presence of active forces. The motion of the center of mass and of individual monomers is calculated. On timeExpand

On the Generalized Langevin Equation for a Rouse Bead in a Nonequilibrium Bath
We present the reduced dynamics of a bead in a Rouse chain which is submerged in a bath containing a driving agent that renders it out-of-equilibrium. We first review the generalized LangevinExpand

Transient behaviour of a polymer dragged through a viscoelastic medium.
We study the dynamics of a polymer that is pulled by a constant force through a viscoelastic medium. This is a model for a polymer being pulled through a cell by an external force, or for an activeExpand

The effect of active fluctuations on the dynamics of particles, motors and DNA-hairpins.
Inspired by recent experiments on the dynamics of particles and polymers in artificial cytoskeletons and in cells, we introduce a modified Langevin equation for a particle in an environment that is aExpand

General Criterion for Harmonicity.
Inspired by Kubo-Anderson Markov processes, we introduce a new class of transfer matrices whose largest eigenvalue is determined by a simple explicit algebraic equation. Applications include the freeExpand

The Perfect Spring
Inspired by Kubo-Anderson Markov processes, we introduce a new class of transfer matrices whose largest eigenvalue is determined by a simple explicit algebraic equation. Applications include the freeExpand
