... In the uncoupled representation good quantum numbers correspond to the eigenvalues of the operators Ŝ12 , Ŝ22 , Ŝ1,z , Ŝ2,z . Since s1,2 = 12 while ms for each particle can take two values, we can list four possible states: |↑↑i, |↑↓i, |↓↑i, |↓↓i. c) Which quantum numbers would you use to label ...

So far, we have studied simple models in which a particle is subjected to a force in one dimension (particle in a box, harmonic oscillator) or forces in three dimensions (particle in a 3-dimensional box). We were able to write the Laplacian, ∇ 2, in terms of Cartesian coordinates, assuming ψ to be a ...

In Sec. 2 we give the definition of the invariance of a Hamiltonian under a unitary transformation that may depend on the time and then we demonstrate the main results of this pap ...
