Fluctuation-dissipation violations in mean-field non-reciprocal spin glasses
Ot Garcés, Demian Levis
We study the out-of-equilibrium dynamics of the spherical Sherrington-Kirkpatrick model with non-reciprocal asymmetric couplings. Rather than assuming stationarity, we derive the c…
Universal transport of active colloids with sensory delay in motility landscapes
Adrià Garcés, Ueli Töpfer, Lucio Isa +2
We experimentally, numerically and analytically explore the diffusive transport of active colloidal particles with sensory delay, navigating motility landscapes in which the self-p…
Dynamics of O(2) excitations in a non-reciprocal medium
Ylann Rouzaire, Daniel JG Pearce, Ignacio Pagonabarraga +1
We investigate emergent dynamics due to non-reciprocity in the model. The lattice XY model, where non-reciprocity stems from vision cone like couplings, can be des…
Time irreversibility and entropy production in non-Hermitian Model A field theories
Matthias Carosi, Ot Garcés, Adrià Garcés +1
We develop a systematic framework to quantify irreversibility in scalar Model A field theories with a generic non-Hermitian term driving the dynamics. Using the stochastic path-int…
Depinning and activated motion of chiral self-propelled robots
Juan Pablo Carrillo-Mora, Adrià Garcés, Demian Levis
We study experimentally, numerically and analytically, the dynamics of a chiral active particle (cm-sized robots), pulled at a constant translational velocity. We show that the sys…
Activity leads to topological phase transition in 2D populations of heterogeneous oscillators
Ylann Rouzaire, Parisa Rahmani, Ignacio Pagonabarraga +2
Populations of heterogeneous, noisy oscillators on a two-dimensional lattice display short-range order. Here, we show that if the oscillators are allowed to actively move in space,…
