Information theory for dimensionality reduction in dynamical systems
Matthew S. Schmitt, Maciej Koch-Janusz, Michel Fruchart +3
The dynamics of many-body systems can often be captured in terms of only a few relevant variables. Mathematical and numerical approaches exist to identify these variables by exploi…
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,…
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…
