Abstract

From the Bogoliubov theory of Superfluidity to the present spin-orbit coupled Bose-Einstein condensates confined in an optical lattice: a theoretical survey

This talk consists of two parts: in the first one I briefly present the Landau criterium and the Bogoliubov theory of superfluidity; in the second one I illustrate the presently realized spin-orbit coupling in a weakly interacting Bose-Einstein condensate confined on a lattice and describe the features of its superfluid phase by an analogy with the standard bulk superfluidity.

Abstract

Cosmic Strings meet Multiferroics: Understanding Topological Defect Formation in Crystals

Jumping from the expanse of galactic scales to land in the laboratory might seem a gargantuan task. Common to both, however, is the the concept of symmetry breaking and in particular the formation of topological defects. Here I discuss the formation of topological defects in multiferroic hexagonal manganites whose ferroelectric behavior enables the direct imaging of these defects. I also show how this material can be used to study the Kibble-Zurek model of topological defect formation in the early universe and give quantitative insights on the number of domains formed during the spontaneous symmetry breaking phase transition. We also uncover a surprising 'beyond Kibble-Zurek' behaviour, and discuss this in the context of the material's properties
