QED Theory of Phase Fluctuati<strong>on</strong>s<br />
Arovas <strong>and</strong> AA, PRB 78 (2008)<br />
phase modes behave as 2+1D phot<strong>on</strong>s, minimally coupled<br />
to the vortex density <strong>and</strong> current<br />
The phase ‘phot<strong>on</strong>s’ produce<br />
retarded interacti<strong>on</strong>s between vortices,<br />
<strong>and</strong> produce a vortex self energy (mass).
