Bosons and fermions in mixed-dimensional optical lattices phase equilibria and quantum phase transitions

Abstract

[ES]: En esta tesis doctoral se ha estudiado el comportamiento de sistemas de mezclas de átomos bosonicos y fermionicos en redes ópticas de dimensionalidad mezclada.Por un lado se han estudiado las características de las transiciones de fase de una mezcla de bosones y fermiones en una red óptica que constriñe los bosones a un dimensión mientras que los fermiones pueden moverse en tres dimensiones. Observando, por un lado, que las transiciones son de primer orden en el caso estrictamente unidimensional. Exceptuando las del vacío a una fase pura de cualquiera de las dos especies. Mientras que en el caso en el que los fermiones pueden moverse en tres dimensiones se observa el cambio de tipo de transición en el caso de la transición de bosones puros a mezcla de bosones y fermiones.Por otro lado se ha estudiado la influencia de los fermiones en la transición de fase cuántica de superfluido a aislante de Mott. Obteniendo el resultado de que para cierta configuración de llenado de bosones en pared óptica, los fermiones apantallan las interacciones entre los bosones, facilitando así la fase superfluida.

This was made possible in practice by the DIPC foundation the first months of my thesis, I must hereby mention Pedro Etxenike here. The CSIC institution during the most part of it, through its Jae PreDoc program.

A thesis submitted to the University of the Basque Country to obtain the degree of Doctor in Physics by Eneko Malatsetxebarria Elizegi Supervised by Dr. Miguel A. Cazalilla, April 2013.
