Excited state quantum phase transition in a driven dicke model
Recent successfull experimental realization of the Dicke Model with a time rependent coupling parameter, have draw the attention in the study of dynamical properties present in the Light-matter interaction model. Althoug some research on the non-equilibrium model has been presented, a rather knew QP...

Aunque ya se han reportado investigaciones del modelo fuera del equilibrio, una nueva transición de fase conocida como transición de fase de estados excitados no ha sido estudiada previamente. Aquí, se presentan que el cambio de la estadística de la fidelidad del estado base y la aparición de una ocupación finita de los niveles de energía, para algunos casos del parámetro de acople, implica la aparición de la ESQPT en el modelo dinámico."--Tomado del Formato de Documento de GradoFísicoPregrado56 hojasapplication/pdfengUniversidad de los AndesFísicaFacultad de CienciasDepartamento de Físicainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaExcited state quantum phase transition in a driven dicke modelTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPFísica cuánticaEntropíaTransición de faseExcitación del espinFísicaPublication473b402a-8853-4e07-97ac-ffb17de82e35virtual::13871-1473b402a-8853-4e07-97ac-ffb17de82e35virtual::13871-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000077194virtual::13871-1ORIGINALu807604.pdfapplication/pdf27172661https://repositorio.uniandes.edu.co/bitstreams/840a6460-4004-4aec-ab10-648b2da726ac/download56d37a92451d46c6a85a4a2e3b87af35MD51TEXTu807604.pdf.txtu807604.pdf.txtExtracted texttext/plain74705https://repositorio.uniandes.edu.co/bitstreams/8920d818-49f7-4087-9b53-95ad4e9b9c23/download63cfe3bb3b06203656e00e94fe524f0bMD54THUMBNAILu807604.pdf.jpgu807604.pdf.jpgIM Thumbnailimage/jpeg8143https://repositorio.uniandes.edu.co/bitstreams/27235515-1e39-42c9-8868-11f09845e2f4/download0dc11f47ed8e0e0faa861cef4bb818caMD551992/40003oai:repositorio.uniandes.edu.co:1992/400032024-03-13 15:03:10.456http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
