Statistical analysis of complex many-body states reveals hidden structure
(January 2)
Statistical mechanics is largely based on the assumption of ergodicity, which is reflected in a quasi-random behavior of corresponding many-particle quantum states. Such a behavior is already mimicked by a single quantum particle in a complex geometry with a wave function resembling a random spatial landscape. Nearly half a century ago, however, silent spatial correlations had been explored by Michael Berry upon superimposing random plane waves. Here we show that corresponding structures also exist in the huge dimensional (Fock) space of quantum fields describing quantum mechanical many-body systems. We show how corresponding correlations in many-body space can be unveiled -- with possible implications for the statistical physics of cold atoms.
