For the Schroedinger equation in 3 dimensions in cubic symmetry, list the first seven excited states (and for each the sum of n12 + n22 + n32) in the notation En1,n2,n3 where E1,1,1 is the ground state.   (List *all* of the ni for each state that give a degenerate energy level (for example, for the first excited state E2,1,1 = E1,2,1 = E1,1,2 and n12 + n22 + n32=6 ))

To generate the excited states for the quantum harmonic oscillator, one repeatedly applies the raising operator ˆa+ to the ground state, increasing the energy by ~ω with each step: ψn = An(ˆa+) nψ0(x) with En = (n + 1 2 )~ω where An is the normalization constant and aˆ± ≡ 1 √ 2~mω (∓ipˆ+ mωxˆ). Given that the normalized ground state wave function is ψ0(x) = mω π~ 1/4 e − mω 2~ x 2 , show that the first...

Please read the case and answer the questions below: 1-3 The employer publishes the South Texas Clarion daily newspaper, employing 726 carriers on 780 routes through the rural Rio Grande river valley. In addition to the Clarion, the carriers deliver seven other newspapers e.g., The Wall Street Journal. The employer operates four distribution centers (warehouses) where carriers pick up the papers to take on their routes. Each distribution center has general manager and several "District Managers" who supervise the work...
