The discussion focuses on the transformation of the operators \( a \) and \( a^\dagger \) under time reversal transformation in quantum mechanics. It is established that the position operator \( x \) remains unchanged while the momentum operator \( p \) transforms to \( -p \). The operators \( a \) and \( a^\dagger \) are shown to remain invariant under time reversal, as demonstrated through their definitions in terms of \( x \) and \( p \). The transformation confirms that \( a \) and \( a^\dagger \) do not change, affirming their fixed nature under time inversion.
