Apparatus for Spin and Heat Transport in Fermi Gases
Abstract
Transport properties provide an important tool to characterize many-body systems. We propose measurements of spin transport in strongly interacting Fermi gases that will test a proposed lower bound on diffusivity as well as predicted signatures of a pseudogap phase. Our experimental apparatus will utilize a homogeneous Fermi gas separated into three regions: a sample and two reservoirs. Non-equilibrium initial conditions in the reservoirs will drive a spin current through the sample, enabling detailed measurements of the spin diffusivity. Our experimental approach can be extended to measurements of heat transport and non-equilibrium states.
