Excitability of Gaussian states with VEVs
Jacqueline Caminiti, Federico Capeccia, Jonathan Sorce
In arXiv:2604.19861, we gave general criteria for when one zero-mean Gaussian state can be excited out of another in a (generalized) free field theory. Here we extend this analysis…
Algebraic locality and non-invertible Gauss laws
Nicholas Holfester, Jonathan Sorce
We study algebraic locality principles on a 2+1D closed lattice in the presence of a Gauss law for a non-invertible symmetry. Prior work in arXiv:2509.03589 showed that when enforc…
Excitability in quantum field theory
Jacqueline Caminiti, Federico Capeccia, Jonathan Sorce
In quantum field theory, it is not always possible to excite one state out of another using only local operators. This paper establishes abstract algebraic criteria for (local) exc…
Bootstrap 2024: Lectures on "The algebraic approach: when, how, and why?"
Jonathan Sorce
These lecture notes formed the basis of a mini-course on algebraic quantum field theory presented at the Bootstrap 2024 conference in Madrid. The goal of the notes is to explain th…
