EnergyDensity Class Reference

Solely calculates the energy density as given by,

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

The \(F_{\mu\nu}\) is the clover. More...

Detailed Description

Solely calculates the energy density as given by,

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

The \(F_{\mu\nu}\) is the clover.
