Direct detection of odd-frequency superconductivity

Odd-frequency superconductivity is a dynamical phenomenon. The time-dependence of the anomalous Green function matters. Therefore, a dynamical response is needed to directly detect odd-frequency superconductivity. We propose a novel type of detection scheme based on two-pulse, time-resolved ARPES noise measurements. Remarkably, the experimental response is directly proportional to the anomalous Green function at unequal times.
