Statistics of work performed by optical tweezers with general time-variation of their stiffness
Petr Chvosta, Dominik Lips, Viktor Holubec +2
We derive an exact expression for the probability density of work done on a particle that diffuses in a parabolic potential with a stiffness varying by an arbitrary piecewise const…
Thermal ratchet effect in confining geometries
Viktor Holubec, Artem Ryabov, Mohammad Hassan Yaghoubi +4
Stochastic model of the Feynman-Smoluchowski ratchet is proposed and solved using generalization of the Fick-Jacobs theory. The theory fully captures nonlinear response of the ratc…
Transport coefficients for a confined Brownian ratchet operating between two heat reservoirs
Artem Ryabov, Viktor Holubec, Mohammad Hassan Yaghoubi +3
We discuss two-dimensional diffusion of a Brownian particle confined to a periodic asymmetric channel with soft walls modeled by a parabolic potential. In the channel, the particle…
On asymptotic behavior of work distributions for driven Brownian motion
Viktor Holubec, Dominik Lips, Artem Ryabov +2
We propose a simple conjecture for the functional form of the asymptotic behavior of work distributions for driven overdamped Brownian motion of a particle in confining potentials.…
Tracer dynamics in a single-file system with absorbing boundary
Artem Ryabov, Petr Chvosta
The paper addresses the single-file diffusion in the presence of an absorbing boundary. The emphasis is on an interplay between the hard-core interparticle interaction and the abso…
Unfolding kinetics of periodic DNA hairpins
Sandra Nostheide, Viktor Holubec, Petr Chvosta +1
DNA hairpin molecules with periodic base sequences can be expected to exhibit a regular coarse-grained free energy landscape (FEL) as function of the number of open base pairs and…
