Packet 13: Bonus 3
In systems like the quantum harmonic oscillator, types of these functions denoted “creation and annihilation” or “a and a dagger” can be used to move between energy levels. For 10 points each:
[10m] Name these functions. In quantum mechanics, observables like position can be associated with self-adjoint, linear versions of these functions.
ANSWER: operators [accept ladder operators or creation operator or annihilation operator or position operator]
[10e] Famously, the position operator does not commute with the operator corresponding to this observable. In classical mechanics, this quantity is set equal to mass times velocity.
ANSWER: momentum
[10h] An important result in quantum mechanics is that all operators that correspond to observables are Hermitian, meaning that these scalars are always real. In the time-independent Schrodinger equation, the energy operator’s values for these scalars are multiplied by the wavefunction.
ANSWER: eigenvalues [accept energy eigenvalues]
