What is recorded here?
Two independent 2008 teams used cold atoms to observe spatial localization of matter waves under controlled conditions. Billy and colleagues released a dilute cloud into a one-dimensional laser-speckle potential and measured stationary exponential density wings. Roati and colleagues used an almost non-interacting potassium condensate in a quasiperiodic optical lattice, testing transport and spatial and momentum profiles. Their different experimental routes probe disorder-related localization; they are one result family here, with two separate source bylines.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
One contribution family with distinct experimental systems, not a joint paper. Billy's negligible-interaction inference concerns dilute wings and weak disorder; its cut-off-dependent effective mobility edge is not a general three-dimensional Anderson transition. Roati realizes an Aubry–André-type quasi-periodic crossover: actual beta=1.1972 broadens/shifts the ideal golden-ratio Delta/J=2 transition. Not proof of interacting many-body localization or localization for every disorder strength.
