Dipolar interactions between domains in lipid monolayers at the air-water interface
(Royal Society of Chemistry, 2016-05)
A great variety of biologically relevant monolayers present phase coexistence characterized by domains formed by lipids in an ordered phase state dispersed in a continuous, disordered phase. From the difference in surface ...
Stability of trapped degenerate dipolar Bose and Fermi gases
(2013-06-14)
Trapped degenerate dipolar Bose and Fermi gases of the cylindrical symmetry with the polarization vector along the symmetry axis are only stable for the strength of dipolar interaction below a critical value. In the case ...
Miscibility in coupled dipolar and non-dipolar Bose-Einstein condensates
(Iop Publishing Ltd, 2017-10-01)
We perform a full three-dimensional study on miscible-immiscible conditions for coupled dipolar and non-dipolar Bose-Einstein condensates (BEC), confined in anisotropic traps. In view of recent experimental studies, our ...
Produção de emaranhamento pela interação dipolar magnética
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2018-08-06)
In this work we consider a bipartite system consisting of magnetic dipoles, initially characterized by product-states uncorrelated until the dynamics of evolution is established by magnetic dipole interaction. We reproduce ...
Phase transition in the two-dimensional dipolar planar rotator model
(Journal of Physics: Condensed Matter, 2017)
Dynamics of the corotating vortices in dipolar Bose-Einstein condensates in the presence of dissipation
(Iop Publishing Ltd, 2014-08-28)
We study the dynamics of a single and a corotating vortex pair in a dipolar Bose-Einstein condensate in the framework of a dissipative Gross-Pitaevskii equation. This simple model enables us to simulate the effect of finite ...
Coexistence of dipolar frustration and criticality in ferromagnets
(American Physical Society, 2018-12-20)
In real magnets the tendency toward ferromagnetism - promoted by exchange coupling - is usually frustrated by dipolar interaction. As a result, the uniformly ordered phase is replaced by modulated (multidomain) phases, ...
Spatial separation of rotating binary Bose-Einstein condensates by tuning the dipolar interactions
(2019-04-04)
We are pointing out relevant anisotropic effects, related to spatial separation and miscibility, due to dipole-dipole interactions in rotating binary dipolar Bose-Einstein condensates by considering symmetric (Dy164-Dy162) ...
Stable and mobile two-dimensional dipolar ring-dark-in-bright Bose-Einstein condensate soliton
(2016-03-01)
We demonstrate robust, stable, mobile two-dimensional (2D) dipolar ring-dark-in-bright (RDB) Bose-Einstein condensate (BEC) solitons for repulsive contact interaction, subject to a harmonic trap along the y direction ...
