How Quorum Sensing Shapes Clustering in Active Matter
L. de Souza, E. F. Teixeira, G. M. Viswanathan +2
Self-propelled particles undergoing persistent motion can accumulate either through excluded-volume interactions or through quorum sensing, where self-propulsion decreases at high…
Yet another exponential Hopfield model
Linda Albanese, Andrea Alessandrelli, Adriano Barra +1
We propose and analyze a new variation of the so-called {\em exponential Hopfield model}, a recently introduced family of associative neural networks with unprecedented storage cap…
Emergent odd viscoelasticity in chiral soft glassy materials
Debarghya Banerjee, Peter Sollich
Rheological properties of chiral active materials have been an important area of research in the recent past, in particular regarding odd terms in their mechanical response. While…
Multifractality and statistical localization in the sparse Barrat-Mézard trap model
Diego Tapias, Peter Sollich
We study within a paradigmatic model for glassy dynamics, the Barrat-Mézard trap model, the effect of a nontrivial network structure in the connectivity among traps. Sparseness of…
Localization and top eigenvalue detection
Diego Tapias, Benedikt Grüger, Reimer Kühn +1
The detection of the top eigenvalue and its corresponding eigenvector in ensembles of random matrices has significant applications across various fields. An existing method, based…
Static vs dynamic rough energy landscapes: Where is diffusion faster?
Dmitrii E. Makarov, Peter Sollich
Molecules in dense environments, such as biological cells, are subjected to forces that fluctuate both in time and in space. While spatial fluctuations are captured by Lifson-Jacks…
