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…
Lattice-dependent orientational order in active crystals
Till Welker, Ricard Alert
Via mechanisms not accessible at equilibrium, self-propelled particles can form phases with positional order, such as crystals, and with orientational order, such as polar flocks.…
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.…
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…
