For shapes that have regular or nearly regular classical behavior (e.g. rectangular or circular) the tunneling rates vary greatly over wide ranges often by several orders of magnitude. However, for well shapes that admit more classically chaotic behavior (e.g. the stadium, the Sinai billiard) the range of tunneling rates narrows, often by orders of magnitude. This dramatic narrowing appears to come from destabilization of periodic orbits in the regular wells that produce the largest and smallest tunneling rates and causes the splitting versus energy relation to take on a possibly universal shape. It is in this sense that we say the quantum chaos regularizes the tunneling rates.<\/jats:p>","DOI":"10.1142\/s0218127412502471","type":"journal-article","created":{"date-parts":[[2012,11,8]],"date-time":"2012-11-08T08:56:12Z","timestamp":1352364972000},"page":"1250247","source":"Crossref","is-referenced-by-count":2,"title":["REGULARIZATION OF TUNNELING RATES WITH QUANTUM CHAOS"],"prefix":"10.1142","volume":"22","author":[{"given":"LOUIS M.","family":"PECORA","sequence":"first","affiliation":[{"name":"Materials Physics and Sensors, U.S. Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HOSHIK","family":"LEE","sequence":"additional","affiliation":[{"name":"Department of Physics, College of William and Mary, Williamsburg, VA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DONG-HO","family":"WU","sequence":"additional","affiliation":[{"name":"Materials Physics and Sensors, U.S. Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,11,8]]},"reference":[{"doi-asserted-by":"publisher","key":"rf1","DOI":"10.1103\/PhysRevLett.81.4537"},{"key":"rf2","first-page":"016204-1","volume":"64","author":"Bies W.
