Resumo: | A uniformly accelerated detector perceives the Minkowski vacuum as a thermal state. In particular, for a massless scalar field, one cannot distinguish these two scenarios -accelerated detector in the vacuum and an inertial detector in contact with a thermal reservoir- just by using a point-like detector. In this work we show that one can probe the existence of acceleration by using an extended detector with dimension perpendicular to the acceleration direction. Also, we verify that the internal degrees of freedom of the detector may get entangled by a process of spontaneous emission, and as such is dependent on the initial state of the detector. It is found that the entropy production and entropy fluxes from out the detector also allow one to tell the two scenarios apart: more internal entangled detectors produce less entropy and vice-versa; the wavelength of the sought particle is the critical length at which the behavior of the two system is inverted. |

In particular, for a massless scalar field, one cannot distinguish these two scenarios -accelerated detector in the vacuum and an inertial detector in contact with a thermal reservoir- just by using a point-like detector. In this work we show that one can probe the existence of acceleration by using an extended detector with dimension perpendicular to the acceleration direction. Also, we verify that the internal degrees of freedom of the detector may get entangled by a process of spontaneous emission, and as such is dependent on the initial state of the detector.

Em particular, para um campo escalar sem massa, os dois cenários -detector acelerado no vácuo e detector inercial em contato com um reservatório térmico- não podem ser diferenciados utilizando-se apenas um detector adimensional. Neste trabalho mostramos que os dois cenários podem ser diferenciados com o uso de um detector estendido de dimensão perpendicular à direção de aceleração. Verificamos também que os graus de liberdade internos do detector podem se correlacionar por meio de emissão espontânea, e portanto, dependem do estado inicial do detector. Foi observado que a produção e fluxos de entropia do detector também permitem distinguir os dois cenários: detectores com graus de liberdade mais emaranhados produzem menos entropia e vice-versa; o comprimento de onda da partícula buscada é uma distância crítica para a qual o comportamento dos dois sistemas se inverte.Submitted by Liliane Ferreira (ljuvencia30@gmail.com) on 2021-01-21T11:15:55Z No. of bitstreams: 2 license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5) Dissertação - Lucas Aurélio de Oliveira Borges - 2020.pdf: 3685486 bytes, checksum: 0f7d27f7967f913d33c5e340072fe204 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2021-01-22T11:56:09Z (GMT) No. of bitstreams: 2 license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5) Dissertação - Lucas Aurélio de Oliveira Borges - 2020.pdf: 3685486 bytes, checksum: 0f7d27f7967f913d33c5e340072fe204 (MD5)Made available in DSpace on 2021-01-22T11:56:09Z (GMT).

In this work we show that one can probe the existence of acceleration by using an extended detector with dimension perpendicular to the acceleration direction. Also, we verify that the internal degrees of freedom of the detector may get entangled by a process of spontaneous emission, and as such is dependent on the initial state of the detector. It is found that the entropy production and entropy fluxes from out the detector also allow one to tell the two scenarios apart: more internal entangled detectors produce less entropy and vice-versa; the wavelength of the sought particle is the critical length at which the behavior of the two system is inverted. |
