Phase structure of compactified $S U (N)$ gauge theories in magnetic backgrounds

Massimo D'Elia, Marco Mariti

We discuss the properties of non-abelian gauge theories formulated on manifolds with compactified dimensions and in the presence of fermionic fields coupled to magnetic backgrounds…

Recent progress on QCD inputs for axion phenomenology

Claudio Bonati, Massimo D'Elia, Marco Mariti +5

The properties of the QCD axion are strictly related to the dependence of strong interactions on the topological parameter theta. We present a determination of the topological prop…

Higher order quark number fluctuations via imaginary chemical potentials in $N_{f} = 2 + 1$ QCD

Massimo D'Elia, Giuseppe Gagliardi, Francesco Sanfilippo

We discuss analytic continuation as a tool to extract the cumulants of the quark number fluctuations in the strongly interacting medium from lattice QCD simulations at imaginary ch…

A local factorization of the fermion determinant in lattice QCD

Marco Cè, Leonardo Giusti, Stefan Schaefer

We introduce a factorization of the fermion determinant in lattice QCD with Wilson-type fermions that leads to a bosonic action which is local in the block fields. The interaction…

Magnetic field effects on the static quark potential at zero and finite temperature

Claudio Bonati, Massimo D'Elia, Marco Mariti +4

We investigate the static $Q Q ˉ$ potential at zero and finite temperature in the presence of a constant and uniform external magnetic field $B$ , for several values of the…

The topological susceptibility in the large-N limit of SU(N) Yang-Mills theory

Marco Cè, Miguel García Vera, Leonardo Giusti +1

We compute the topological susceptibility of the SU(N) Yang-Mills theory in the large-N limit with a percent level accuracy. This is achieved by measuring the gradient-flow definit…

$θ$ dependence of 4D $S U (N)$ gauge theories in the large- $N$ limit

Claudio Bonati, Massimo D'Elia, Paolo Rossi +1

We study the large- $N$ scaling behavior of the $θ$ dependence of the ground-state energy density $E (θ)$ of four-dimensional (4D) $S U (N)$ gauge theories and two-dimensional (2D) $CP…

Roberge-Weiss endpoint at the physical point of $N_{f} = 2 + 1$ QCD

Claudio Bonati, Massimo D'Elia, Marco Mariti +3

We study the phase diagram of $N_{f} = 2 + 1$ QCD in the $T - μ_{B}$ plane and investigate the critical point corresponding to the onset of the Roberge-Weiss transition, which is found f…

$θ$ dependence in $S U (3)$ Yang-Mills theory from analytic continuation

Claudio Bonati, Massimo D'Elia, Aurora Scapellato

We investigate the topological properties of the $S U (3)$ pure gauge theory by performing numerical simulations at imaginary values of the $θ$ parameter. By monitoring the dependenc…

Domain decomposition, multi-level integration and exponential noise reduction in lattice QCD

Marco Cè, Leonardo Giusti, Stefan Schaefer

We explore the possibility of computing fermionic correlators on the lattice by combining a domain decomposition with a multi-level integration scheme. The quark propagator is expa…
