An update on the determination of the sphaleron rate in finite temperature QCD
Nicolò Bellini, Claudio Bonanno, Francesco D'Angelo +3
The sphaleron rate is a key phenomenological quantity both for the axion thermal production in the Early Universe and the Chiral Magnetic Effect occurring in the Quark-Gluon Plasma…
Dirac Spectral Density in N=2+1 QCD at T=230 MeV
Andrei Alexandru, Claudio Bonanno, Massimo D'Elia +1
We compute the renormalized Dirac spectral density in QCD at physical quark masses, temperature MeV and system size fm. To that end, we perform a…
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 twisted gradient flow strong coupling without topological freezing
Claudio Bonanno, Jorge Luis Dasilva Golán, Massimo D'Elia +2
We investigate the role of topology on the lattice determination of the strong coupling renormalized via gradient flow. To deal with the topological freezing of st…
Electrical conductivity of the Quark-Gluon Plasma in the presence of strong magnetic fields
Giorgio Almirante, Nikita Astrakhantsev, V. V. Braguta +5
We compute the electrical conductivity of the strongly interacting medium in the presence of strong magnetic background fields, , and for different values of the temp…
Non-perturbative determination of the QCD sphaleron rate
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
The strong sphaleron rate, i.e., the rate of real time QCD topological transitions, is a key phenomenological quantity, playing a fundamental role in several physical contexts. In…
