Reentrant phase behavior in binary topological flocks with nonreciprocal alignment
Tian Tang, Yu Duan, Yu-qiang Ma
We study a binary metric-free Vicsek model involving two species of self-propelled particles aligning with their Voronoi neighbors, focusing on a weakly nonreciprocal regime, where…
Phase Coexistence in Nonreciprocal Quorum-Sensing Active Matter
Yu Duan, Jaime Agudo-Canalejo, Ramin Golestanian +1
Motility and nonreciprocity are two primary mechanisms for self-organization in active matter. In a recent study [Phys. Rev. Lett. 131, 148301 (2023)], we explored their joint infl…
Statistical properties of microphase and bubbly phase-separated active fluids
Giordano Fausti, Cesare Nardini, Michael E Cates
In phase-separated active fluids, the Ostwald process can go into reverse leading to either microphase separation or bubbly phase separation. We show that the latter is formed of t…
Designing complex behaviors using transition-based allosteric self-assembly
Jakob Metson
Allosteric interactions occur when binding at one part of a complex affects the interactions at another part. Allostery offers a high degree of control in multi-species processes,…
Enhanced stability and chaotic condensates in multi-species non-reciprocal mixtures
Laya Parkavousi, Navdeep Rana, Ramin Golestanian +1
Random non-reciprocal interactions between a large number of conserved densities are shown to enhance the stability of the system towards pattern formation. The enhanced stability…
Mechanistic rules for de novo design of enzymes
Michalis Chatzittofi, Jaime Agudo-Canalejo, Ramin Golestanian
Enzymes are nano-scale machines that have evolved to drive chemical reactions out of equilibrium in the right place at the right time. Given the complexity and specificity of enzym…
