Shot noise and universal Fano factor as a characterization of strongly correlated metals

Shot noise and universal Fano factor as a characterization of strongly correlated metals

Shot noise measures out-of-equilibrium current fluctuations and is a powerful tool to probe the nature of current-carrying excitations in quantum systems. Recent shot-noise measurements in the heavy-fermion strange metal YbRh_{2}Si_{2} exhibit a strong suppression of the Fano factor (F)—the ratio of...
