Collective oscillations in a three-dimensional spin model with non-reciprocal interactions
Laura Guislain, Eric Bertin
We study the onset of collective oscillations at low temperature in a three-dimensional spin model with non-reciprocal short-range interactions. Performing numerical simulations of…
Yielding is an absorbing phase transition with vanishing critical fluctuations
Tristan Jocteur, Shana Figueiredo, Kirsten Martens +2
The yielding transition in athermal complex fluids can be interpreted as an absorbing phase transition between an elastic, absorbing state with high mesoscopic degeneracy and a flo…
Biased motility-induced phase separation: from chemotaxis to traffic jams
Eric Bertin, Alexandre Solon
We propose a one-dimensional model of active particles interpolating between quorum sensing models used in the study of motility-induced phase separation (MIPS) and models of conge…
Tailoring the overlap distribution in driven mean-field spin models
Laura Guislain, Eric Bertin
In a statistical physics context, inverse problems consist in determining microscopic interactions such that a system reaches a predefined collective state. A complex collective st…
Discontinuous phase transition from ferromagnetic to oscillating states in a nonequilibrium mean-field spin model
Laura Guislain, Eric Bertin
We study a nonequilibrium ferromagnetic mean-field spin model exhibiting a phase with spontaneous temporal oscillations of the magnetization, on top of the usual paramagnetic and f…
