A type of polar self-propelled particle generates a torque that makes it naturally drawn to higher-density areas. The collective behaviour this induces in assemblies particles constitutes new form phase separation active fluids.

We study polar molecules in a stack of strongly confined pancake traps. When dipole moments point perpendicular to the planes of the traps and are sufficiently strong, the system is stable against collapse but attractive interaction between molecules in different layers leads to the formation of dipolar chains, analogously to the chaining phenomenon in classical rheological electro- and magneto...

Equilibrium molecular dynamics simulation and the Green-Kubo formalismwere used to calculate self-diffusion coefficient, shear viscosity, and thermalconductivity for 30 different quadrupolar two-center Lennard-Jones fluids alongthe bubble line and in the homogeneous liquid. It was systematically investi-gated how anisotropy, i.e. elongation, and quadrupole momentum influence the...
