Coherent forward scattering peak induced by Anderson localization.
Numerical simulations show that, at the onset of Anderson localization, the momentum distribution of a coherent wave packet launched inside a random potential exhibits, in the forward direction, a novel interference peak that complements the coherent backscattering peak. An explanation of this phenomenon in terms of maximally crossed diagrams predicts that the signal emerges around the localiza...
متن کاملCoherent Backscattering and Anderson Localization of Light
In this review we discuss localization of waves by multiple scattering. In the weak case, also known as coherent backscattering, there is a twofold enhancement of the reflected intensity in the back direction. We discuss the origin of this effect, its shape with reflection angle as well as the influence of finite sample size and absorption on this shape. This discussion of the properties of the...
متن کاملTailored Anderson localization with partially coherent light
Anderson localization and partially coherent light are at first sight unrelated, if one thinks in terms of interference. However, Anderson localization can be observed with non-coherent light, since a partially coherent beam can be viewed as a superposition of randomly phased components, which localize independently in a disordered media [1]. This gives rise to the question of how much transver...
متن کاملQuantum non-Markovianity induced by Anderson localization
As discovered by P. W. Anderson, excitations do not propagate freely in a disordered lattice, but, due to destructive interference, they localise. As a consequence, when an atom interacts with a disordered lattice, one indeed observes a non-trivial excitation exchange between atom and lattice. Such non-trivial atomic dynamics will in general be characterised also by a non-trivial quantum inform...
متن کاملMeasurement-based tailoring of Anderson localization of partially coherent light
We put forward an experimental configuration to observe transverse Anderson localization of partially coherent light beams with a tunable degree of first-order coherence. The scheme makes use of entangled photons propagating in disordered waveguide arrays, and is based on the unique relationship between the degree of entanglement of a pair of photons and the coherence properties of the individu...
