Parity Breaking in Classical and Quantum Fluids by Dylan Reynolds

Explore the fascinating world of parity breaking in classical and quantum fluids in this comprehensive seminar by Dylan Reynolds from The City College of New York. Delve into the concept of odd viscosity, a dissipationless transport coefficient that arises in parity broken fluids, and its implications for both classical 2D systems and quantum systems. Examine the extension of these principles to 3D active matter and discover a wide range of novel phenomena. Investigate observable effects such as forces on obstacles and chiral edge modes at fluid boundaries, which can be seen across various scales of physics. Learn how odd viscosity and parity-breaking can bridge our understanding between seemingly unrelated systems. Begin with a phenomenological perspective of the transport coefficients allowed by the symmetries of the viscosity tensor. Analyze specific systems exhibiting parity breaking effects, including classical systems like Hele-Shaw flows and ferrofluids, as well as quantum systems such as polaritons and fractional quantum Hall fluids. Gain insights into the microscopic mechanisms leading to odd viscosity in certain cases. Throughout the seminar, discover connections between various systems and highlight their commonalities. Conclude with an overview of future research objectives aimed at elaborating and expanding upon these connections in the field of parity breaking in fluids.
