A linear harmonic oscillator of charge e is perturbed by an electric field t in the positive x-direction. The first order change in the energy level is zero why ? Calculate the energy upto second order.
Added by Joice J.
Step 1
The Hamiltonian for a linear harmonic oscillator is given by H = p^2/2m + 1/2 mω^2 x^2, where p is the momentum, m is the mass, ω is the angular frequency, and x is the position. Show more…

Show that the time rate of change of mechanical energy for a damped, undriven oscillator is given by $d E / d t=-b v^{2}$ and hence is always negative. (Hint: Differentiate the expression for the mechanical energy of an oscillator, $E=\frac{1}{2} m v^{2}+\frac{1}{2} k x^{2}$, and use Eq. 13.32.)
A two-dimensional harmonic oscillator has energy $E=$ $\hbar \omega_{0}\left(n_{x}+n_{y}+1\right),$ where $n_{x}$ and $n_{y}$ are integers beginning with zero. ( $a$ ) Justify this result based on the energy of the one-dimensional oscillator. (b) Sketch an energy-level diagram similar to Figure 5.21 , showing the lowest 4 energy levels. For each level, show the value of $E$ (in units of $\hbar \omega_{0}$ ), the quantum numbers $n_{x}$ and $n_{y},$ and the degeneracy. (c) Show that the degeneracy of each level is equal to $n_{x}+n_{y}+1$
Show that the time rate of change of mechanical energy for a damped, undriven oscillator is given by $d E / d t=-b v^{2}$ and hence is always negative. Proceed as follows: Differentiate the expression for the mechanical energy of an oscillator, $E=\frac{1}{2} m v^{2}+\frac{1}{2} k x^{2},$ and use Equation 15.31.
