Abstract
- We propose a framework to study the onset of Anderson localization in disordered systems. The idea is to expose waves propagating in a random scattering environment to a sequence of short dephasing pulses. The system responds through coherence peaks forming at specific echo times, each echo representing a particular process of quantum interference. We suggest a concrete realization for cold gases, where quantum interferences are observed in the momentum distribution of matter waves in a laser speckle potential, and discuss in detail corresponding echoes in momentum space for sequences of one and two dephasing pulses. Our proposal defines a challenging but arguably realistic framework promising to yield unprecedented insight into the mechanisms of Anderson localization. [ABSTRACT FROM AUTHOR]
