Unformatted text preview: conjugate”. Namely “hermitian” operators have the property that O op = O ↑ op Properties of Hermitian Operators: 1. The expectation value of an hermitian operator is a real number: O op = O ↑ op ⇒ <O op > = <O op > * 2. If the expectation value of the operator O op is a real number then O op is hermitian: <O op > = <O op > * ⇒ O op = O ↑ op Note that (A op B op ) ↑ = B ↑ op A ↑ op We will prove this later after we learn “Dirac Notation”....
