The Fermi-Pasta-Ulam problem as a challenge for the foundations of physics / A. Carati, L. Galgani, A. Giorgilli. - In: CHAOS. - ISSN 1054-1500. - 15:1(2005 Mar), pp. 015105.015105.1-015105.015105.8.
Abstract:
The Fermi-Pasta-Ulam (FPU) problem is discussed in connection with its physical relevance, and it is shown how apparently there exist only two possibilities: either the FPU problem is just a curiosity, or it has a fundamental role for the foundations of physics, casting a new light on the relations between classical and quantum mechanics. To this end, a short review is given of the main conceptual proposals that have been advanced. Particular emphasis is given to the perspective of a metaequilibrium scenario, which appears to be the only possible one for the FPU paradox to survive in the physically relevant case of infinitely many particles.
