Measuring the Hydrodynamic Linear Response of a Unitary Fermi Gas
PHYSICAL REVIEW LETTERS, 123(16).
TL;DR:
It is shown that the time-dependent change of the density profile is sensitive to the thermal conductivity, which controls the relaxation rate of the temperature gradients and hence the responses arising from adiabatic and isothermal compression.
