<b>Title:</b> Measurement of the mobility edge in 3D Anderson localization<br>
<b>Date:</b> 15/1/14<br>
<b>Time:</b> 4 pm<br>
<b>Location:</b> JA 8.11<br>
<b>Abstract:</b> Several decades of studies of Anderson localization in disorder have confirmed that in 3D there is a critical energy, the mobility edge, separating localized states from diffusive one. An assessment of the mobility edge in a real system that
can also be described by a microscopic Hamiltonian is however still missing, because of the challenging nature of the theory, simulations and experiments. We now employ a Bose-Einstein condensate in a disordered optical potential, where the control of the
atom-atom interaction allows to produce a fully localized system with a narrow energy distribution. We then employ a modulation technique to produce a controlled excitation and from a study of the system losses we determine the position of the mobility edge.
Our study reveals a peculiar dependence on the strength of disorder, which will be useful to constrain current theoretical studies of 3D Anderson localization.<o:p></o:p></p>
