2. The ladder operators can be used to determine the lowest eigenstate (ground state) of the harmonic oscillator by using the following relation of the annihilation operator, à alo) - 0 This equation is fundamental to ladder operators and implies that it is not possible to step down further in energy than the ground state. Determine the ground state wave function h(x (i.e. [0) using the relation above and the following information The annihilation operator is defined as: ) ·The...

I need part c please :)
2. What makes the operators a and a', defined in problem 1 e, of the last homework, useful, is that they make it easy to manipulate the solutions to the harmonic oscillator. The general behavior of the operators when they operate on harmonic oscillator wavefunctions, yv, is as follows: a' SQRT(v+1) i.c., operating with a' on one of the harmonic oscillator eigenfunctions, ww, converts it to the next highest eigenfunction, ψν+1-Therefore at is...
