It is argued that the two parameter scaling breaks down in the vicinity of the transition to the localized phase, signaling a slowing-down of dynamics.

The diffusion constant is derived as a function of all relevant microscopic parameters and it is shown that coherent multiple scattering induces significant weak localization effects.

An atom-optics quantum-chaotic system, the quasiperiodic kicked rotor, is realized experimentally, which is equivalent to a 3D disordered system that allows us to demonstrate the Anderson metal-insulator transition.

The observation indicates that the Anderson three dimensional metal-insulator transition is of second order, with a critical exponent independent of the microscopic details; the average value 1.63±0.05 agrees very well with the numerically predicted value ν=1.58.

Theoretical prediction of a frequency-independent transport time around a sharp atomic resonance is verified and the effect of the residual velocity of the atoms at long times is observed, reducing strongly the diffusion constant.
Coherent light transport in a cold strontium cloud.

The effect of internal structure as the key mechanism for the contrast reduction observed with a rubidium cold cloud is confirmed and an enhancement factor close to 2 in the helicity preserving channel is found, in agreement with theoretical predictions.
Disorder and interference: localization phenomena

- Physics
- 6 May 2010
The specific problem we address in these lectures is the problem of transport and localization in disordered systems, when interference is present, as characteristic for waves, with a focus on…
