Derivative of x being hermitian
Webx is Hermitian. It is significant to note that it has been possible to prove that p x ≡−iℏ∂/∂x is a Hermitian operator only because we have assumed that the functions ϕ and ψ have integrable squares and consequently vanish at infinity. Problem 5.2. Show that the operator p x 2 is Hermitian. Quantum Mechanics 5-3 WebIt seems to be worth stressing that, to check (1), it is not necessary to exploit the definition of adjoint operator, A † that, generally, does not exist when D ( A) is not dense. If D ( A) is dense, the Hermitian operator A is said to be symmetric. In your case (s) A := T n and D ( T n) = S ( R), the Hilbert space H being L 2 ( R).

It's gradient is defined just like for any function : h μ ∂ μ ϕ ( x) = lim ϵ → 0 ϵ − 1 ( ϕ ( x + ϵ h) − ϕ ( x)) For a real scalar field, ϕ ( x) is a hermitian operator for every x. Therefore, the formula above gives : ( ∂ μ ϕ ( x)) † = ∂ μ ϕ ( x)
