Entanglement and phase transitions in a exciton-polariton bec confined in a photonic crystal nanocavity

In this work we study a polariton-exciton system confined in photonic crystal nanocavity with embedded quantum dot. Using a separable state of the type BCS, for the matter subsystem, product by a coherent state, for the photonic mode, we compute the ground state energy of N polaritons. Also, we char...

Usando un estado separable del tipo BCS, para el subsistema excitónico confinado en el punto cuántico, y un estado coherente, para el modo electromagnético con_nado en la nanocavidad, se calcula la energía del estado base para el sistema de N polaritones excitónicos. También se realiza una caracterización de las coherencias cuánticas del sistema calculando discordia y entrelazamiento a partir de la llamada matriz densidad de pares. Finalmente, introduciendo temperatura y campo magnético en nuestro modelo, podemos evidenciar la señal de una posible transición de fase en las correlaciones cuánticas del sistema.application/pdfspaUniversidad Nacional de Colombia, Bogotáhttp://revistas.unal.edu.co/index.php/momento/article/view/45070Universidad Nacional de Colombia Revistas electrónicas UN MOMENTO - Revista de FísicaMOMENTO - Revista de FísicaMOMENTO - Revista de Física; núm. 47 (2013); 77-86 0121-4470Guirales, Guillermo A. and Vinck-Posada, Herbert and Rodríguez, Boris A.
