For adiabatic modulation of an optically trapped Brownian particle, measurements yield $\\ln W\\propto (A_{\\rm c} - A)^{\\mu}$ with $\\mu = 1.5$. The theory gives $\\mu=3/2$ in the adiabatic limit and predicts a crossover to $\\mu=2$ scaling as $A$ approaches the bifurcation point where the metastable state disappears.", "revisions": [ { "version": "v1", "updated": "2002-04-29T23:07:08.000Z" } ], "analyses": { "keywords": [ "universality", "modulated potential displays scaling behavior", "adiabatic limit", "metastable state disappears", "bifurcation point" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
