“Chiral Hydrodynamics: From Active Matter to Quantum Hall Fluids”

ABSTRACT
Our understanding of the universal phenomenon in many-body systems ranging from subatomic to astronomical scales relies largely on the hydrodynamical framework. Thus the discovery of new hydrodynamic effect opens new understanding in a multitude of physical systems.  Such hydrodynamical effect recently has come to fore from Quantum Hall Effect (QHE), where Avron, Seiler, and Zograf showed that the viscosity of QH fluid is purely dissipation-less and is the off-diagonal component of the total viscosity tensor, dubbed `odd’ or `Hall’ viscosity. It turns out that odd viscosity is not limited to QH, but a special symmetry allowed term of a parity broken system in two dimensions. In this talk, I will outline several fascinating fluid phenomena induced by odd viscosity term such as “odd” torque, “odd” surface waves and  “odd” bubbles and discuss their applicability in a wide class of systems ranging from chiral active matter to fractional quantum Hall effect.
