Yang--Mills topology on four-dimensional triangulations
Giuseppe Clemente, Massimo D'Elia, Dániel Németh +1
We consider 4D gauge theories coupled to gravity in the Causal Dynamical Triangulations (CDT) approach, focusing on the topological classification of the gauge path integra…
Full QCD with milder topological freezing
Claudio Bonanno, Giuseppe Clemente, Massimo D'Elia +2
We simulate QCD at the physical point combining open and periodic boundary conditions in a parallel tempering framework, following the original proposal by M. Hasenbusch…
The QCD topological susceptibility at high temperatures via staggered fermions spectral projectors
Andreas Athenodorou, Claudio Bonanno, Claudio Bonati +7
The QCD topological observables are essential inputs to obtain theoretical predictions about axion phenomenology, which are of utmost importance for current and future experimental…
Topological susceptibility of QCD from staggered fermions spectral projectors at high temperatures
Andreas Athenodorou, Claudio Bonanno, Claudio Bonati +7
We compute the topological susceptibility of QCD with physical quark masses in the high-temperature phase, using numerical simulations of the theory discretized on a spac…
Strategies for the Determination of the Running Coupling of -dimensional QED with Quantum Computing
Giuseppe Clemente, Arianna Crippa, Karl Jansen
We propose to utilize NISQ-era quantum devices to compute short distance quantities in -dimensional QED and to combine them with large volume Monte Carlo simulations and per…

Alessandro Candido, Giuseppe Clemente, Massimo D'Elia +1
We discuss the discretization of Yang-Mills theories on Dynamical Triangulations in the compact formulation, with gauge fields living on the links of the dual graph associated with…
Spectral Analysis of Causal Dynamical Triangulations via Finite Element Method
Fabio Caceffo, Giuseppe Clemente
We examine the dual graph representation of simplicial manifolds in Causal Dynamical Triangulations (CDT) as a mean to build observables, and propose a new representation based on…

We illustrate the application of Quantum Computing techniques to the investigation of the thermodynamical properties of a simple system, made up of three quantum spins with frustra…
Spectral Methods in Causal Dynamical Triangulations
Giuseppe Clemente, Massimo D'Elia, Alessandro Ferraro
We show recent results of the application of spectral analysis in the setting of the Monte Carlo approach to Quantum Gravity known as Causal Dynamical Triangulations (CDT), discuss…
Spectral Projectors Method for Staggered Fermions
Claudio Bonanno, Giuseppe Clemente, Massimo D'Elia +1
We extend the spectral projectors method to staggered fermions. Applying the index theorem to the staggered Dirac operator it is possible to work out an expression for the topologi…
Topology via Spectral Projectors with Staggered Fermions
Claudio Bonanno, Giuseppe Clemente, Massimo D'Elia +1
The spectral projectors method is a way to obtain a theoretically well posed definition of the topological susceptibility on the lattice. Up to now this method has been defined and…
