Ranking nodes in directed networks via continuous-time quantum walks
Paola Boito, Roberto Grena
Four new centrality measures for directed networks based on unitary, continuous-time quantum walks (CTQW) in dimensions -- where is the number of nodes -- are presented, te…
Quantum hub and authority centrality measures for directed networks based on continuous-time quantum walks
Paola Boito, Roberto Grena
In this work we introduce, test and discuss three quantum methods for computing hub and authority centrality scores in directed networks. The methods are based on unitary, continuo…
Superconformal Vacua in N=2 Usp(4) Gauge Theories
Roberto Auzzi, Roberto Grena
We study the dynamics of a confining vacuum in N=2 USp(4) gauge theory with n_f=4. The vacuum appears to be a deformed conformal theory with nonabelian gauge symmetry. The low-ener…
Almost Conformal Vacua and Confinement
Roberto Auzzi, Roberto Grena, Kenichi Konishi
Dynamics of confining vacua which appear as deformed superconformal theory with a non-Abelian gauge symmetry, is studied by taking a concrete example of the sextet vacua of ${\cal…
Confinement, asymptotic freedom and renormalons in type 0 string duals
Roberto Grena, Simone Lelli, Michele Maggiore +1
Type 0B string theory has been proposed as the dual description of non-supersymmetric SU(N) Yang-Mills theory coupled to six scalars, in four dimensions. We study numerically and a…
