Partial Entropy production of active particles with hidden states in potentials
Jacob Knight, Gunnar Pruessner
Partially observed stochastic systems can appear (almost) time-reversal symmetric while in fact operating far from equilibrium. The present work extends the perturbative framework…
Microscopic theory of soft run-and-tumble particles
Rosalba Garcia-Millan, Ziluo Zhang, Luca Cocconi +4
Soft, repulsive run-and-tumble particles display emergent effective interactions as they appear to stick to each other in spite of the absence of attractive forces. This effective…
Effective attraction by repulsion
Rosalba Garcia-Millan, Luca Cocconi, Ziluo Zhang +4
Repulsive self-propelled particles tend to cluster, leading to Motility-Induced Phase Separation (MIPS). By analogy with equilibrium phase separation, the onset of MIPS has been as…
Exact results and instabilities in the harmonic approximation of active crystals
Connor Roberts, Gunnar Pruessner
Condensates of active particles such as cells form almost-crystalline lattices which play a central role in many biological systems. Typically, their properties have been determine…
Conditional splitting probabilities for hidden-state inference in drift-diffusive processes
Emir Sezik, Jacob Knight, Henry Alston +4
Splitting probabilities quantify the likelihood of particular outcomes out of a set of mutually-exclusive possibilities for stochastic processes and play a central role in first-pa…
Stochastic cloaking: concealing a region from diffusive particles
Connor Roberts, Ziluo Zhang, Helder Rojas +4
We introduce "stochastic cloaking," where a region of space is concealed from an ensemble of diffusing particles whose individual trajectories are governed by a stochastic (Langevi…
