Anosova, Maria and Gattringer, Christof and Iqbal, Nabil and Sulejmanpasic, Tin (2022) 'Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter.', Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021).
We study a recently proposed formulation of U(1) lattice field theory with electric and magnetic matter based on the Villain formulation. This discretization allows for a duality that gives rise to relations between weak and strong gauge coupling. There exists a self-dual value of the gauge coupling where one may study the model as a function of the remaining matter coupling. Using Monte Carlo simulations based on a worldline/worldsheet representation of the system we evaluate order parameters for spontaneous breaking of self-duality. We find that in some interval of the matter coupling self-duality becomes broken spontaneously. We determine the endpoints of this interval and study the nature of the corresponding critical points. Finally we explore the system away from the self-dual gauge coupling and show that when crossing the self-dual point a first order jump is seen in the order parameters.
