Expectation Value (Quantum Density)

Available identifiers

expected (mean) value of a quantum-mechanical observable, calculated from a density

Defining Formula: $⟨ \hat{O} ⟩ \equiv t r (\hat{O} \hat{ρ})$
$ρ$ symbol represents Quantum Density Operator
$\hat{O}$ symbol represents Quantum Mechanical Operator
$⟨ \hat{O} ⟩$ symbol represents Expectation Value (Quantum Density)
