Ladder Operator

  1. Feb 19, 2010 #1
    Hello, I am trying to understand some principles in my book.

    Is the lowering operator [tex]A[/tex], the conjugate of the raising operator [tex]A^{+}[/tex]?

    Also I was reading that the lowering operator [tex]A[/tex] is not Hermitian since it and its adjoint [tex]A^{+}[/tex] are not equal? Does that imply that [tex]A^{+}[/tex] is not Hermitian.

    Thank you.

    TThe answer to every question you ask is yes. I assume the book you have will have an explicit expression for the raising and lowering operators, and you can compute the answers yourself.
