Irreversibility in active matter systems: Fluctuation theorem and mutual information

L Dabelow, S Bo, R Eichhorn - Physical Review X, 2019 - APS
We consider a Brownian particle which, in addition to being in contact with a thermal bath, is
driven by fluctuating forces which stem from active processes in the system, such as self …

Thermodynamics of computations with absolute irreversibility, unidirectional transitions, and stochastic computation times

G Manzano, G Kardeş, É Roldán, DH Wolpert - Physical Review X, 2024 - APS
Developing a thermodynamic theory of computation is a challenging task at the interface of
nonequilibrium thermodynamics and computer science. In particular, this task requires …

Loopy Lévy flights enhance tracer diffusion in active suspensions

K Kanazawa, TG Sano, A Cairoli, A Baule - Nature, 2020 - nature.com
Brownian motion is widely used as a model of diffusion in equilibrium media throughout the

Nonreciprocal forces enable cold-to-hot heat transfer between nanoparticles

SAM Loos, S Arabha, A Rajabpour, A Hassanali… - Scientific Reports, 2023 - nature.com
We study the heat transfer between two nanoparticles held at different temperatures that
interact through nonreciprocal forces, by combining molecular dynamics simulations with …

Rapid-prototyping a Brownian particle in an active bath

JT Park, G Paneru, C Kwon, S Granick, HK Pak - Soft Matter, 2020 - pubs.rsc.org
Particles kicked by external forces to produce mobility distinct from thermal diffusion are an
iconic feature of the active matter problem. Here, we map this onto a minimal model for …

Field master equation theory of the self-excited Hawkes process

K Kanazawa, D Sornette - Physical Review Research, 2020 - APS
A field theoretical framework is developed for the Hawkes self-excited point process with
arbitrary memory kernels by embedding the original non-Markovian one-dimensional …

Revealing the nonequilibrium nature of a granular intruder: the crucial role of non-Gaussian behavior

D Lucente, M Viale, A Gnoli, A Puglisi, A Vulpiani - Physical Review Letters, 2023 - APS
The characterization of the distance from equilibrium is a debated problem in particular in
the treatment of experimental signals. If the signal is a one-dimensional time series, such a …

Ubiquitous power law scaling in nonlinear self-excited Hawkes processes

K Kanazawa, D Sornette - Physical review letters, 2021 - APS
The origin (s) of the ubiquity of probability distribution functions with power law tails is still a

Periodic potential can enormously boost free-particle transport induced by active fluctuations

K Białas, J Łuczka, J Spiechowicz - Physical Review E, 2023 - APS
Active fluctuations are detected in a growing number of systems due to self-propulsion
mechanisms or collisions with an active environment. They drive the system far from …
