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…
Irreversibility and symmetry breaking in the creation and annihilation of defects in active living matter
Avraham Beer, Efraim Dov Neimand, Yuv Agarwal +4
Active living matter continuously creates and annihilates topological defects in a process that remains poorly understood. Here, we investigate these dynamics in two distinct activ…
Actuation of Cell Sheets in 3D
Kirsten Endresen, Aniruddh Murali, Birte Geerds +2
The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liqui…
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…
