What is Quantum Field Theory?

Quantum Field Theory (QFT) is a unified language, a toolbox, a set of techniques for modern theoretical physicists. And it has had tremendous success with it’s, in my eyes, brightest achievement being the standard model of particle physics, but also the explanation of superconductivity, Hall effect and others. Important things! So what is it? First, […]

Of Symmetry, Other Symmetries and Non-Symmetries

One of the most remarkable concepts in modern physics is symmetry. The structure of our world just seems to be organised in different symmetric structures, which, luckily, can be described using mathematics. This approach has been very successful since the mathematical foundation was laid out by Emmy Noether (1882-1935) in 1918 in Noether’s Theorem. Noether’s […]
