Phase transition in a Rabi coupled two-component Bose-Einstein condensate
Amandine Aftalion, Christos Sourdis
This paper deals with the study of the phase transition of the wave functions of a segregated two-component Bose-Einstein condensate under Rabi coupling. This yields a system of tw…
Painlevé-II profile of the shadow kink in the theory of light-matter interaction in nematic liquid crystals
Christos Sourdis
We confirm a prediction that the recently introduced shadow kink defect in the theory of light-matter interaction in nematic liquid crystals is described to main order by a solutio…
Linear non-degeneracy of the 1d blow-up limit in the phase segregation of Bose-Einstein condensates
Christos Sourdis
We show that the kernel of the linearization of the blow-up problem at the regular part of the interface that separates segregated BECs is one-dimensional, generated by translation…
Matched asymptotics for large solutions to the Gelfand-Liouville problem in two-dimensional, doubly connected domains
Christos Sourdis
In this paper we provide a formal matched asymptotic analysis for large solutions to the Gelfand-Liouville problem in planar, doubly connected domains in the plane. Using these, we…
