Bose-Einstein condensation (BEC), appearing upon cooling a gas of bosons below a critical temperature, has been given a striking demonstration in dilute atomic gases at temperatures below 200nK. By confining photons in a semiconductor microcavity, and strongly coupling them to electronic excitations, one may create polaritons. These bosonic quasi-particles are billion times lighter than rubidium atoms, thus theoretically allowing a BEC at standard cryogenic temperatures. Here we present experiments giving compelling evidence for a BEC of polaritons. Above a critical density, we observe massive occupation of the ground state, developing from a thermalized distribution of the polariton population at (16-20) K. The spontaneopus onset of a coherent state is manifested by the increase of temporal coherence, build-up of spatial long-range order and the reduction of the thermal noise observed in second order coherence experiments. All of these indicate spontaneous onset of a macroscopic quantum phase.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Jacek Kasprzak\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639215419\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639215410\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/13\/2010\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 176\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.59lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.41d","brand":"Jacek Kasprzak","offers":[{"title":"Paperback","offer_id":47305527066879,"sku":"9783639215410","price":73.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f50285d9-983b-49c6-8c5c-992db8167e8f.jpg?v=1758831126","url":"https:\/\/www.whiterainbookhouse.com\/products\/bose-condensation-of-exciton-polaritons-jacek-kasprzak-9783639215410","provider":"WR Book House","version":"1.0","type":"link"}
