Hamiltonian description of nonreciprocal interactions
Yu-Bo Shi, Roderich Moessner, Ricard Alert +1
In a vast class of systems, which includes members as diverse as sedimenting particles and bird flocks, interactions do not stem from a potential, and are in general nonreciprocal.…
Bistability of cellular traction on strain-stiffening substrates
Irina Pi-JaumÃ, Jaume Casademunt, Ricard Alert
To migrate, cells exert traction forces on the extracellular matrix (ECM) -- a biopolymer network that often exhibits nonlinear strain-stiffening elasticity. Cellular tractions can…
Active screws: Emergent active chiral nematics of spinning self-propelled rods
Debarghya Banerjee, Lauritz Hahn, Ricard Alert
Several types of active agents self-propel by spinning around their propulsion axis, thus behaving as active screws. Examples include cytoskeletal filaments in gliding assays, magn…
Nonequilibrium noise emerging from broken detailed balance in active gels
Ashot Matevosyan, Frank Jülicher, Ricard Alert
In thermodynamic equilibrium, the fluctuation-dissipation theorem links thermal fluctuations and dissipation. Biological systems, however, are driven out of equilibrium by internal…
Discontinuous transition to active nematic turbulence
Malcolm Hillebrand, Ricard Alert
Active fluids exhibit chaotic flows at low Reynolds number known as active turbulence. Whereas the statistical properties of the chaotic flows are increasingly well understood, the…
Modes of Mechanical Guidance of Adhesion-Independent Cell Migration
Hanna Luise Gertack, Peter A. E. Hampshire, Claudia Wohlgemuth +2
Adhesion-independent migration is a prominent mode of cell motility in confined environments, yet the physical principles that guide such movement remain incompletely understood. W…
