What are Hermitian operators examples?
Examples of Hermitian Operators in Physics: Common examples include the position and momentum operators.
The expectation values for position and momentum can be calculated using the position operator and momentum operator respectively.Is the linear momentum operator a Hermitian operator?
The momentum operator is always a Hermitian operator (more technically, in math terminology a "self-adjoint operator") when it acts on physical (in particular, normalizable) quantum states.
then it is automatically Hermitian. is second-order and linear. which is identical to the previous definition except that quantities have been extended to be complex (Arfken 1985, p.
How do you prove that the operator is Hermitian?
To prove that a quantum mechanical operator  is Hermitian, consider the eigenvalue equation and its complex conjugate.
Since both integrals equal a, they must be equivalent.
This equality means that  is Hermitian.
Eigenfunctions of a Hermitian operator are orthogonal if they have different eigenvalues.
