In such heterostructures, cooperative dynamics of excitons and photon-emission properties are strongly influenced by collective surface plasmon modes of metal nanoparticles constituting a plasmonic cavity. To gain insight into the cooperative dynamics of quantum emitters in such a cavity, we have developed a quantum mechanical approach treating the quantum emitter, surface plasmon, and photon decrees of freedom on the same footing. This allows us to account for multiple-scale interactions between plasmon modes and quantum emitters. Furthermore, the interactions can naturally be partitioned into coherent and incoherent couplings resulting in a generalized version of plasmonic Dicke model. Examination of associated phase diagram in both equilibrium and non-equilibrium regimes allows us to identify the polariton condensate, superradiant, and various lasing regimes. Finally, we performed numerical simulations of plasmonic response of a linear array formed by either metal nanorods or asymmetric metal nanoantennas. The calculations show that such nanostructures have potential for achieving strong coupling regime and realizing predicted cooperative regimes.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ECondensed Matter Seminar\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Condensed Matter Seminar, Dr. Andrei Piryatinski, Los Alamos National Laboratory"}],"uid":"34720","created_gmt":"2019-05-06 19:31:55","changed_gmt":"2019-05-06 19:36:26","author":"tdavis333","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-05-16T16:00:00-04:00","event_time_end":"2019-05-16T17:00:00-04:00","event_time_end_last":"2019-05-16T17:00:00-04:00","gmt_time_start":"2019-05-16 20:00:00","gmt_time_end":"2019-05-16 21:00:00","gmt_time_end_last":"2019-05-16 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"621409":{"id":"621409","type":"image","title":"Andrei Piryatinski, Los Alamos National Laboratory","body":null,"created":"1557171268","gmt_created":"2019-05-06 19:34:28","changed":"1557171268","gmt_changed":"2019-05-06 19:34:28","alt":"","file":{"fid":"236690","name":"Andrei Piryatinski.jpg","image_path":"\/sites\/default\/files\/images\/Andrei%20Piryatinski_0.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/Andrei%20Piryatinski_0.jpg","mime":"image\/jpeg","size":11981,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Andrei%20Piryatinski_0.jpg?itok=smOK8UWb"}}},"media_ids":["621409"],"related_links":[{"url":"https:\/\/cnls.lanl.gov\/External\/people\/Andrei_Piryatinski.php","title":"Dr. Andrei Piryatinski"}],"groups":[],"categories":[],"keywords":[{"id":"960","name":"physics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003Etara.davis@physics.gatech.edu\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
