Explore the concept of topological frequency conversion in this 32-minute conference talk by Ivar Martin, recorded as part of the Transport and Efficient Energy Conversion in Quantum Systems Conference at the Kavli Institute for Theoretical Physics. Delve into the study of transport and energy conversion in quantum systems away from equilibrium, examining recent progress in applying quantum information ideas to understand thermodynamical concepts and the creation of quantum coherent systems. Discover the Bernoulli model, nontopological regime, and frequency component protocol as Martin discusses experiments and outlines key concepts. Gain insights into fundamental challenges in optimal protocols for energy and information transport, as well as state preparation, while learning about the intersection of statistical physics, condensed matter, and atomic physics in this cutting-edge research area.
