We focus on the density of states (DOS) near the maximum \\rho(r,t) which is the amount of time spent by the process at a distance r from the maximum. We develop a path integral approach to study functionals of the maximum of BM, which allows us to study the full probability density function (PDF) of \\rho(r,t) and obtain an explicit expression for the moments, \\langle [\\rho(r,t)]^k \\rangle, for arbitrary integer k. We also study near-extremes of constrained BM, like the Brownian bridge. Finally we also present numerical simulations to check our analytical results.", "revisions": [ { "version": "v1", "updated": "2013-05-28T13:50:17.000Z" } ], "analyses": { "subjects": [ "05.40.Fb", "02.50.Cw", "05.40.Jc" ], "keywords": [ "brownian motion", "near-extreme statistics", "full probability density function", "path integral approach", "arbitrary integer" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2013, "month": "Dec", "volume": 111, "number": 24, "pages": 240601 }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013PhRvL.111x0601P" } } }
