Homework Statement
Let x be the position coordinate for a particle that moves in one dimension and let [tex]p=-i\hbar*d/dx[/tex] be the usual momentum operator . State whether each of the following operators is self-adjoint, anti-self-adjoint([tex]A^{\dagger}
=A[/tex] , unitary([tex] A^{\dagger}A=1[/tex], or, if none of the above , what the adjoint is:
xxp, xpx, xpp+ppx, d^2/dx^2 , d^3/dx^3,e^p
Homework Equations
The Attempt at a Solution
I will perform the first operator xxp. [tex]p=-i\hbar*d/dx[/tex], therefore xxp=x^2*[tex]p=-i\hbar*d/dx[/tex]=2*x*[tex]-\hbar*i[/tex]? So would this operator be a self-adjointed one ?
