This spatial profile is initially created in thermal equilibrium by a perturbing potential. After the perturbation is abruptly extinguished, the dominant spatial Fourier component exhibits an exponentially decaying (thermally diffusive) mode and a decaying oscillatory (first sound) mode, enabling independent measurement of the thermal conductivity and the shear viscosity directly from the time-dependent evolution.}, number={9}, journal={PHYSICAL REVIEW LETTERS}, author={Wang, Xin and Li, Xiang and Arakelyan, Ilya and Thomas, J.
