Description

I give a short introduction to Tomita-Takesaki modular theory. After defining the framework, I will give an intuition by discussing it for finite-dimensional Hilbert spaces. Subsequently, we will turn to quantum field theory: I will sketch how modular theory presents an intimate connection between entanglement of the vacuum and space-time symmetries.
