Here is a listing of my mathematica notebooks. The most recent of any of these notebooks can all be obtained from my github Mathematica repository.
The Wolfram CDF player can also be used to view a number of these notebooks after download.
Some integrals related to QM hydrogen atom energy expectation values.
Some trig integrals that I didn't feel like doing manually.
More Gaussian integrals and some that Mathematica didn't know how to do.
Some Gaussian integrals.
Some variational method calculations for QM energy estimation.
Hankle function fitting for e^{-b|x|} and related plots.
Stripped down example notebook for stackoverflow question about Derivative[2] not behaving well.
Stripped down example notebook for stackoverflow question about Listable attribute defaults.
Plot of Gaussian weighted cosine, its Fourier transform, and figure for perturbation of Harmonic oscillator system.
Sinusoid plot turned on at t_0 and ongoing from there.
Some trig integrals that Mathematica didn't evaluate correctly. Don't trust a tool without thinking whether the results are good!
Another worked variational method problem.
Another worked variational method problem.
Another worked variational method problem. Looks like I've learned about the /. operator for evaluating variables with values.
Some sinc function plots. Learned how to use Manipulate to make sliders.
Some energy expectation value calculations.
Some vector addition and function translation figures.
Some integrals of first order linear polynomials.
Some step and rect function plots.
Another stackoverflow mathematica question. Why no output in my plot. Learned about Mathematica local and global variables as a result.
A sanity check on a rotation matrix calculated as part of a problem set.
Exam problem 2a. Calculate the matrix of a Perturbation Hamiltonian $-\boldsymbol{\mu}_d \cdot \mathbf{E}$ with respect to the $n=2$ hydrogen atom wave functions.
A new attempt at Desai 24.4.3 from scratch. This one has an error, as did the original. The original is now fixed.
