Detailed Description

Observable for calculating the plaquette, energy and euclidean time topological charge.

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. Energy definition:

\[ E = -\frac{1}{64|\Lambda|} \sum_{n\in\Lambda} \sum_{\mu<\nu} \left(\tilde{C}_{\mu\nu}(n)\right)^2. \]

Topological charge definition:

\[ q(n_e) = \frac{1}{32\pi^2} \sum_{n\in N^3} \epsilon_{\mu\nu\rho\sigma} \mathrm{tr}\left[F_{\mu\nu}(n)F_{\rho\sigma}(n)\right], \]

where \(n_e\) is the position in the lattice in Euclidean time. \(F_{\nu\mu}\) is the clover.
