Entropy measurement of nonequilibrium phonon heat transport

Abstract Entropy, as a fundamental concept in thermodynamics, provides a powerful tool for understanding the behavior of nonequilibrium systems. However, measuring time-dependent entropy in nonequilibrium, nonstationary processes remains largely unexplored. Here, we report the experimental measureme...
