Physicists from the Cavendish Laboratory in Cambridge have created the first two-dimensional version of the Bose glass, a novel phase of matter that challenges statistical mechanics. The details of the study have been published in Nature.
As the name suggests, the Bose glass has some glassy properties and within it all particles are localised. This means that each particle in the system sticks to itself, not mixing with its neighbours. If coffee was localised, then when stirring milk into the coffee, the intricate pattern of black and white stripes would remain forever, instead of washing out to an average.
