Topological defects in out-of-equilibrium systems
Ylann Rouzaire
In this PhD thesis, we study topological defects in two-dimensional non-equilibrium systems, focusing on active extensions of the XY model, including activity, mobility and non-rec…
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…
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,…
Non-Reciprocal Interactions Reshape Topological Defect Annihilation
Ylann Rouzaire, Daniel JG Pearce, Ignacio Pagonabarraga +1
We show how non-reciprocal ferromagnetic interactions between neighbouring planar spins in two dimensions, affect the behaviour of topological defects. Non-reciprocity is introduce…
Dynamics of Topological Defects in the noisy Kuramoto Model in two dimensions
Ylann Rouzaire, Demian Levis
We consider the two-dimensional (2D) noisy Kuramoto model of synchronization with short-range coupling and a Gaussian distribution of intrinsic frequencies, and investigate its ord…
Defects Superdiffusion and Unbinding in a 2D XY Model of Self-Driven Rotors
Ylann Rouzaire, Demian Levis
We consider a non-equilibrium extension of the two-dimensional (2D) XY model, equivalent to the noisy Kuramoto model of synchronization with short-range coupling, where rotors sitt…
