I use Mathematica for symbolic and numerical computations in most of my Physics projects. If you are interested in looking at or reusing the code from any of my publications, let me know by writing to fidel.s (at) gmail (dot) com

In 2019 I prepared some problems aiming to introduce Mathematica and improve the coding skills of people with a Physics background but not necessarily experienced in functional programming. While the Wolfram language has changed significantly since then, you may still find something useful in the following:

Mathematica basics
Ladder operators for the anharmonic oscillator
N-body choreographies
Finite N Sachdev-Ye-Kitaev model
Large N Sachdev-Ye-Kitaev model
Neural networks in Mathematica
Tensor models I
Tensor models II
