Entropy production in non-reciprocal polar active mixtures
Kim L. Kreienkamp, Sabine H. L. Klapp
The out-of-equilibrium character of active systems is often twofold, arising from both the activity itself and from non-reciprocal couplings between constituents. A well-establishe…
Inference of a time delay in stochastic systems
Robin A. Kopp, Sabine H. L. Klapp, Deepak Gupta
Time delay is ubiquitous in many experimental and real-world situations. It is often unclear whether time delay plays a significant role in observed phenomena, and if it does, how…
Nonequilibrium fluctuations in a harmonic trap with annealed stochastic stiffness
Deepak Gupta, Sabine H. L. Klapp
We provide a comprehensive analysis of the positional dynamics and average thermodynamics of an overdamped Brownian particle subject to both, harmonic confinement and annealed diso…
Synchronization and exceptional points in nonreciprocal active polar mixtures
Kim L. Kreienkamp, Sabine H. L. Klapp
Many active matter systems consist of different particle types that interact via nonreciprocal couplings. Such nonreciprocal couplings can lead to the spontaneous emergence of time…
Nonreciprocal field theory for decision-making in multi-agent control systems
Andrea Lama, Mario di Bernardo, Sabine H. L. Klapp
Field theories for complex systems traditionally focus on collective behaviors emerging from simple, reciprocal pairwise interaction rules. However, many natural and artificial sys…
Self-assembly and time-dependent control of active and passive triblock Janus colloids
Juri Franz Schubert, Salman Fariz Navas, Sabine H. L. Klapp
We perform Brownian Dynamics (BD) simulations to explore the self-assembly of a two-dimensional model system of triblock Janus colloids as an example of "patchy" colloids forming c…
