When is nonreciprocity relevant?
Giulia Garcia Lorenzana, David Martin, Yael Avni +4
Nonreciprocal interactions are widely observed in nonequilibrium systems, from biological or sociological dynamics to open quantum systems. Despite the ubiquity of nonreciprocity,…
The transition to collective motion in nonreciprocal active matter: coarse graining agent-based models into fluctuating hydrodynamics
David Martin, Daniel Seara, Yael Avni +2
Two hallmarks of non-equilibrium systems, from active colloids to animal herds, are agents motility and nonreciprocal interactions. Their interplay creates feedback loops leading t…
Sociohydrodynamics: data-driven modelling of social behavior
Daniel S. Seara, Jonathan Colen, Michel Fruchart +3
Living systems display complex behaviors driven by physical forces as well as decision-making. Hydrodynamic theories hold promise for simplified universal descriptions of socially-…
Dynamical phase transitions in the nonreciprocal Ising model
Yael Avni, Michel Fruchart, David Martin +2
Nonreciprocal interactions in many-body systems lead to time-dependent states, commonly observed in biological, chemical, and ecological systems. The stability of these states in t…
Nonreciprocal Ising model
Yael Avni, Michel Fruchart, David Martin +2
Systems with nonreciprocal interactions generically display time-dependent states. These are routinely observed in finite systems, from neuroscience to active matter, in which glob…
