In the last decade this remarkable phenomenon found a semiclassical explanation in terms of pairs of classical orbits with small action differences. So far, however, the scope of this theory has, by and large, been restricted to single-particle systems. I will discuss an extension of this program to chaotic systems with a large number of particles. Our approach is based on introduction of two-dimensional symbolic dynamics which allows an effective representation of periodic orbits in many-particle chaotic systems with local homogeneous interactions. Using this representation we show that for a large number of particles the dominant correlation mechanism among periodic orbits essentially differs from the one of the single-particle theory. Its implications on spectral properties of many-particle quantum systems will be discussed as well.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Quantum chaos in many-particle systems"}],"uid":"27664","created_gmt":"2015-10-09 10:41:46","changed_gmt":"2017-04-13 21:17:59","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-10-21T16:00:00-04:00","event_time_end":"2015-10-21T17:00:00-04:00","event_time_end_last":"2015-10-21T17:00:00-04:00","gmt_time_start":"2015-10-21 20:00:00","gmt_time_end":"2015-10-21 21:00:00","gmt_time_end_last":"2015-10-21 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:amorain@gatech.edu\u0022\u003Eamorain@gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
