Ultrafast directed transport via energy recuperation in non-Markovian systems
Mateusz WIÅniewski, Jakub Spiechowicz
A recent pioneering experiment [Nat. Commun. 16, 10114 (2025)] demonstrated that a driven overdamped colloidal particle in a harmonic trap immersed in a viscoelastic fluid can recu…
Can the Brownian diffusion coefficient be reconstructed from Lyapunov exponents?
I. G. Marchenko, I. I. Marchenko, D. Ivashchenko +2
We consider an ac-driven particle moving in a spatially periodic and symmetric potential. In the zero- temperature limit, for the analyzed parameter set, its dynamics is non-chaoti…
Absolute negative mobility in a one-dimensional overdamped system driven by active fluctuations
K. BiaÅas, P. Hänggi, J. Spiechowicz
Absolute negative mobility (ANM) is one of the most paradoxical transport phenomena in which a setup moves on average in a direction opposite to the applied force. According to the…
Memory-induced current reversal of Brownian motors
Mateusz WiÅniewski, Jakub Spiechowicz
Kinetics of biological motors such as kinesin or dynein is notably influenced by viscoelastic intracellular environment. The characteristic relaxation time of the cytosol is not se…
Giant enhancement of transport driven by active fluctuations: impact of inertia
K. BiaÅas, J. Spiechowicz
Recently, a paradoxical effect has been demonstrated in which transport of a free Brownian particle driven by active fluctuations in the form of white Poisson shot noise can be sig…
Memory-controlled random bit generator
Mateusz WiÅniewski, Jakub Spiechowicz
Nowadays a bit is no longer a mere abstraction but a physical quantity whose manipulation governs both operation of modern technologies and theoretical frontiers of fundamental sci…
