In this presentation we show that metadynamics, when used to simulate CPN−1, allows to address efficiently of freezing of topological charge, to reconstruct the free energy of the topological charge F(Q) and to compute the topological susceptibility as a function of the coupling and of the volume. We discuss possible extensions to QCD.

Abstract
In this presentation we show that metadynamics, when used to simulate CPN−1, allows to address efficiently of freezing of topological charge, to reconstruct the free energy of the topological charge F(Q) and to compute the topological susceptibility as a function of the coupling and of the volume. We discuss possible extensions to QCD.| File | Dimensione | Formato | |
