After learning that QFT describes particles as excitations of underlying fields, I've been trying to gain a more definite understanding of what it means; I came across this paper:
https://iopscience.iop.org/article/10.1088/1361-6404/aaa032
Does the author say anything that is misleading?
If his approach is correct, I intend to dig into the equations and write my own Monte Carlo code for visualizing the fields. The author has a freely available code, but writing my own would help me understand this stuff better myself (I hope!).
Later edit: Uh oh, if it's misleading to think of quantum fields as harmonic oscillators filling space, as claimed here - https://physics.stackexchange.com/q...field-an-infinite-set-of-harmonic-oscillators - then we have a problem.
