Detailed Description

Observable for calculating the plaquette.

Plaqeutte definition:

\[ P = \frac{1}{16|\Lambda|} \sum_{n\in\Lambda} \sum_{\mu < \nu} \Re \mathrm{tr} P_{\mu\nu}, \]

where

\[ P_{\mu\nu}=U_\mu(n) U_{\nu}(n+\hat{\mu}) U_{\mu}(n+\hat{\nu})^\dagger U_{\nu} (n)^\dagger \]

is the plquette.
