1. Localisation in 2+1 dimensional SU(3) pure gauge theory at finite temperature / Giordano, Matteo
I study the localisation properties of low Dirac eigenmodes in 2+1 dimensional SU(3) pure gauge theory, both in the low-temperature, confined and chirally-broken phase and in the high-temperature, deconfined and chirally-restored phase, by means of numerical lattice simulations. [...]

2. High statistics lattice study of stress tensor correlators in pure SU(3) gauge theory / Borsányi, Sz. ; Fodor, Z. ; Giordano, M. ; Katz, S. D. ; et al
We compute the Euclidean correlators of the stress tensor in pure SU(3) Yang-Mills theory at finite temperature at zero and finite spatial momenta with lattice simulations. [...]

3. Deconfinement, chiral transition and localisation in a QCD-like model / Giordano, Matteo ; Katz, Sándor ; Kovács, Tamás ; Pittler, Ferenc
We study the problems of deconfinement, chiral symmetry restoration and localisation of the low Dirac eigenmodes in a toy model of QCD, namely unimproved staggered fermions on lattices of temporal extension N T = 4. [...]

4. An Anderson-like model of the QCD chiral transition / Giordano, Matteo ; Kovács, Tamás ; Pittler, Ferenc
We study the problems of chiral symmetry breaking and eigenmode localisation in finite-temperature QCD by looking at the lattice Dirac operator as a random Hamiltonian. [...]

5. An Ising-Anderson model of localisation in high-temperature QCD / Giordano, Matteo ; Kovács, Tamás ; Pittler, Ferenc
We discuss a possible mechanism leading to localisation of the low-lying Dirac eigenmodes in high-temperature lattice QCD, based on the spatial fluctuations of the local Polyakov lines in the partially ordered configurations above T c . [...]

6. Comments on high-energy total cross sections in QCD / Giordano, Matteo ; Meggiolaro, Enrico
We discuss how hadronic total cross sections at high energy depend on the details of QCD, namely on the number of colours Nc and the quark masses. [...]

8. Hadronic total cross sections at high energy and the QCD spectrum / Matteo Giordano ; Enrico Meggiolaro
We show how to obtain the leading energy dependence of hadronic total cross sections, in the framework of the nonperturbative approach to soft high-energy scattering based on Wilson-loop correlation functions, if certain nontrivial analyticity assumptions are satisfied. [...]
