Resumo: In this work we study the photon blockade and antiblockade effects in a system of neutral atoms with a two-level structure, in the limit where induced dipole-dipole interactions mediated by light are relevant. Such system is an interesting alternative to cold gases platforms with Rydberg atoms, with applications in quantum optics and quantum information protocols. For an ensemble of few atoms driven by a laser field, we monitor the photon statistics and the population dynamics of the excited states, identifying the regime of parameters under which blockade or antiblockade is achieved. Furthermore we study the correlations, non-classicality and entanglement of the emitted photons through the photon-photon correlations function and the Cauchy-Schwarz and Bell’s inequalities, with the aim of obtaining a source of pairs of photons strongly correlated and entangled.

Tal sistema mosta-se uma alternativa interessante à plataformas de gases frios com átomos de Rydberg, possuindo aplicações em óptica quântica e em protocolos de informação quântica. Para um conjunto de alguns átomos interagindo com um campo de radiação externo, nós monitoramos a estatística da luz e a dinâmica populacional dos estados de excitações, identificando o regime de parâmetros sob os quais os efeitos de bloqueio e antibloqueio se manifestam. Além disso, nós estudamos as correlações, não-classicalidade e emaranhamento dos fótons emitidos através das funções de correlação fóton-fóton e das desigualdades de Cauchy-Schwarz e de Bell, com o objetivo de obter uma fonte de pares de fótons fortemente correlaciionados e emaranhados.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)engUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Física - PPGFUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessEfeito de bloqueioEfeito de antibloqueioCIENCIAS EXATAS E DA TERRA::FISICA::FISICA ATOMICA E MOLECULARBlockade and antiblockade effects with near-ground state neutral atomsEfeito de bloqueio e antibloqueio com átomos neutros próximos do estado fundamentalinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis600600b43a718b-463b-4ef7-8928-ee05dffbde70reponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALBlockade and Antiblockade effects with near-ground state neutral atoms.pdfBlockade and Antiblockade effects with near-ground state neutral atoms.pdfDissertação de mestradoapplication/pdf7526295https://repositorio.ufscar.br/bitstream/ufscar/17438/1/Blockade%20and%20Antiblockade%20effects%20with%20near-ground%20state%20neutral%20atoms.pdfd82fd91b6ea1bd591a644f8479878960MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8810https://repositorio.ufscar.br/bitstream/ufscar/17438/5/license_rdff337d95da1fce0a22c77480e5e9a7aecMD55TEXTBlockade and Antiblockade effects with near-ground state neutral atoms.pdf.txtBlockade and Antiblockade effects with near-ground state neutral atoms.pdf.txtExtracted texttext/plain140376https://repositorio.ufscar.br/bitstream/ufscar/17438/6/Blockade%20and%20Antiblockade%20effects%20with%20near-ground%20state%20neutral%20atoms.pdf.txt6d742673858eaa42b2fd63ca30cc9697MD56THUMBNAILBlockade and Antiblockade effects with near-ground state neutral atoms.pdf.jpgBlockade and Antiblockade effects with near-ground state neutral atoms.pdf.jpgIM Thumbnailimage/jpeg5222https://repositorio.ufscar.br/bitstream/ufscar/17438/7/Blockade%20and%20Antiblockade%20effects%20with%20near-ground%20state%20neutral%20atoms.pdf.jpgce5afe774ed114e3a012070e24f9cbe9MD57ufscar/174382023-09-18 18:32:33.902oai:repositorio.ufscar.br:ufscar/17438Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:32:33Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false
