Ultrafast directed transport via energy recuperation in non-Markovian systems
Mateusz WIśniewski, 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…
Active fluctuations drive inertia-free absolute negative mobility in soft and living matter
K. Białas, 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. The simplest sys…
Giant enhancement of transport driven by active fluctuations: impact of inertia
K. Białas, 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 Wiśniewski, 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…
Inertia-induced mechanism for giant enhancement of transport generated by active fluctuations
K. Białas, J. Spiechowicz
Active matter is one of the hottest topics in physics nowadays. As a prototype of living systems operating in viscous environments it has usually been modeled in terms of the overd…
Memory-induced current reversal of Brownian motors
Mateusz Wiśniewski, 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…
Approach to nonequilibrium: from anomalous to Brownian diffusion via non-Gaussianity
I. G. Marchenko, I. I. Marchenko, J. Łuczka +1
Recent progress in experimental techniques such as single particle tracking allows to analyze both nonequilibrium properties and approach to equilibrium. There are examples showing…
Dynamics of non-Markovian systems: Markovian embedding vs effective mass approach
Mateusz Wiśniewski, Jakub Spiechowicz
Dynamics of non-Markovian systems is a classic problem yet it attracts an everlasting activity in physics and beyond. A powerful tool for modeling such setups is the Generalized La…
Giant increase of diffusion by small rise of friction
I. G. Marchenko, I. I. Marchenko, V. Aksenova +2
Diffusion coefficient usually decreases when friction increases. We analyze the opposite behavior in the paradigmatic system consisting of an inertial Brownian particle moving in a…
Intriguing properties of transport at the microscales: Langevin equation approach
J. Spiechowicz, J. Łuczka
We present a perspective of simple models of nonequilibrium directed transport described in terms of a Langevin equation formalism. We consider a Brownian particle under various ci…
Memory-induced absolute negative mobility
M. Wiśniewski, J. Spiechowicz
Non-Markovian systems form a broad area of physics that remains greatly unexplored despite years of intensive investigations. The spotlight is on memory as a source of effects that…

Mateusz Wiśniewski, Jerzy Łuczka, Jakub Spiechowicz
Analysis of non-Markovian systems and memory induced phenomena poses an everlasting challenge for physics. As a paradigmatic example we consider a classical Brownian particle of ma…
Effective mass approach to memory in non-Markovian systems
M. Wiśniewski, J. Łuczka, J. Spiechowicz
Recent pioneering experiments on non-Markovian dynamics done e.g. for active matter have demonstrated that our theoretical understanding of this challenging yet hot topic is rather…

Mechanism for giant enhancement of transport induced by active fluctuations
Karol Białas, Jakub Spiechowicz
Understanding the role of active fluctuations in physics is a problem in statu nascendi appearing both as a hot topic and a major challenge. The reason for this is the fact that th…

Diffusion of small particles is omnipresent in a plentiful number of processes occurring in Nature. As such, it is widely studied and exerted in almost all branches of sciences. It…
Periodic potential can enormously boost free particle transport induced by active fluctuations
K. Białas, J. Łuczka, J. Spiechowicz
Active fluctuations are detected in a growing number of systems due to self-propulsion mechanisms or collisions with active environment. They drive the system far from equilibrium…

Anomalous transport in driven periodic systems: distribution of the absolute negative mobility effect in the parameter space
Mateusz Wiśniewski, Jakub Spiechowicz
Absolute negative mobility is one of the most paradoxical forms of anomalous transport behaviour. At the first glance it contradicts the superposition principle and the second law…
Velocity multistability vs ergodicity breaking in a biased periodic potential
