Zapraszamy na seminarium 20.4.2021

We have the pleasure to invite you to the Particle Theory Seminar on Tuesday, April 20 at 12:15:
Speakers: Błażej Ruba, Piotr Korcyl (Inst. of Theor. Phys., Jagiellonian University)
Title: Study of a lattice 2-group gauge model
Abstract: In this talk we discuss a simple model belonging to the class of 2-group gauge systems based on the simplest symmetry group Z_2. Models of this type have independent degrees of freedom associated to both links and plaquettes subject to a certain constraint. We will present in details the  construction of this model, discuss the expected dynamics in different regions of phase space which we will corroborate with numerical results from Monte Carlo simulations.
