Localisation of Dirac eigenmodes and confinement in gauge theories: the Roberge-Weiss transition
Marco Cardinali, Massimo D'Elia, Francesco Garosi +1
Ample numerical evidence from lattice calculations shows a strong connection between the confining properties of gauge theories at finite temperature and the localisation propertie…
Deconfinement transition and localization of Dirac modes in finite-temperature gauge theory on the lattice
György Baranka, Matteo Giordano
We study the localization properties of the eigenmodes of the staggered Dirac operator across the deconfinement transition in finite-temperature pure gauge theory on…
Equation of state of a hot-and-dense quark gluon plasma: lattice simulations at real vs. extrapolations
Szabolcs Borsanyi, Zoltan Fodor, Matteo Giordano +4
The equation of state of the quark gluon plasma is a key ingredient of heavy ion phenomenology. In addition to the traditional Taylor method, several novel approximation schemes ha…
Besov-Laplace priors in density estimation: optimal posterior contraction rates and adaptation
Matteo Giordano
Besov priors are nonparametric priors that can model spatially inhomogeneous functions. They are routinely used in inverse problems and imaging, where they exhibit attractive spars…
Localisation of Dirac modes in gauge theories and Goldstone's theorem at finite temperature
Matteo Giordano
I discuss the possible effects of a finite density of localised near-zero Dirac modes in the chiral limit of gauge theories with degenerate fermions. I focus in particular on…
On the inability of Gaussian process regression to optimally learn compositional functions
Matteo Giordano, Kolyan Ray, Johannes Schmidt-Hieber
We rigorously prove that deep Gaussian process priors can outperform Gaussian process priors if the target function has a compositional structure. To this end, we study information…
