Résumé
On analyse la stabilité d'une texture de superfluide 3He-A en présence d'un courant superfluide J. Se limitant aux configurations dépendantes seulement de z, on trouve trois régimes stables; deux d'entre eux montrent la briseur de la symétrie axiale où le vecteur [MATH] forme une hélice autour du courant.
Abstract
We analyze the stability of textures in superfluid 3He-A in the presence of a superflow J. Specializing to purely z dependent configurations, we find three regions in parameter space, which are stable. Two of them exhibit the breakdown of azimuthal symetry where [MATH] is no longer aligned with Jz but winds around it in a form of hélix.
