Resumo: | In this work we consider a bipartite system consisting of magnetic dipoles, initially characterized by product-states uncorrelated until the dynamics of evolution is established by magnetic dipole interaction. We reproduce the dynamic behavior of the entanglement produced by the magnetic dipole interaction through its temporal dependence, connection with local quantum coherences or symmetries of initial states and interaction parameters, thus establishing criteria that extremize the entanglement. We also investigated the entanglement production capacity of the magnetic dipole interaction for some classes of states with lower purities, with and without initial entanglement, thus identifying relevant aspects between purity, symmetry and necessary local quantum coherences. We show, above all, that some classes of partially entangled states can preserve or generate maximum entanglement under magnetic dipole interaction for different instants of time. |

Reproduzimos o comportamento dinâmico do emaranhamento produzido pela interação dipolar magnética através de sua dependência temporal, conexão com coerências quânticas locais ou simetrias de estados iniciais e parâmetros de interação, estabelecendo assim critérios que extremizam o emaranhamento. Também investigamos a capacidade de produção de emaranhamento da interação dipolar magnética para algumas classes de estados com purezas menores, com e sem emaranhamento inicial, identificando assim aspectos relevantes entre pureza, simetria e coerências quânticas locais necessárias. Mostramos sobretudo, que algumas classes de estados parcialmente emaranhados podem preservar ou gerar o máximo emaranhamento sob interação dipolar magnética para instantes de tempo distintos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em FísicaUFSMBrasilFísicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessCoerência quânticaEmaranhamentoInteração dipolar magnéticaConcurrenceQuantum coherenceEntanglementMagnetic dipolar interactionConcurrenceCNPQ::CIENCIAS EXATAS E DA TERRA::FISICAProdução de emaranhamento pela interação dipolar magnéticaEntanglement yield by the magnetic dipolar interactioninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMaziero, Jonashttp://lattes.cnpq.br/1270437648097538Carara, Marcos Andréhttp://lattes.cnpq.br/1334485128053939Pinto, Diogo de Oliveira Soareshttp://lattes.cnpq.br/5312105238639903CV: http://lattes.cnpq.br/9116334321973709Pinto, Douglas Franco100500000006600832c6bda-ec6d-4308-9152-fd4f204fe619c45a50a5-767f-4610-9ba4-95e70cee11bb120f38dc-57e4-4911-b437-0754d21d7897c3bc6899-0d84-4f3b-a2f2-3c30b14f1258reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGFISICA_2018_PINTO_DOUGLAS.pdfDIS_PPGFISICA_2018_PINTO_DOUGLAS.pdfDissertação de Mestradoapplication/pdf9304244http://repositorio.ufsm.br/bitstream/1/15566/1/DIS_PPGFISICA_2018_PINTO_DOUGLAS.pdff3dd8cc43936ac27a5a40d2d1ebb89efMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
