On the possibility of a new electric effect in ultrathin superfluid films

We predict that the propagation of the third sound in a film is accompanied by the emergence of the electric field in the surrounding space, which can be observed by modern methods. It has been shown that the influence of thermally activated vortices on this effect is weak even near the superfluid t...

Beschreibung
Zusammenfassung:	We predict that the propagation of the third sound in a film is accompanied by the emergence of the electric field in the surrounding space, which can be observed by modern methods. It has been shown that the influence of thermally activated vortices on this effect is weak even near the superfluid transition.
