Odd Viscosity in Active Matter: Microscopic Origin and 3D Effects
Odd Viscosity in Active Matter: Microscopic Origin and 3D Effects
In common fluids, viscosity is associated with dissipation. However, when time-reversal-symmetry is broken a new type of non-dissipative `viscosity' may emerge. Recent theories and experiments on classical 2D systems with active spinning particles have heightened interest in odd viscosity, but a microscopic theory for it in active materials is still …
