Non-perturbative renormalization for lattice massive QED: the ultraviolet problem
Simone Fabbri, Vieri Mastropietro, Bruno Renzi
We consider a lattice regularization, preserving Ward Identities (WI) and with a Wilson term, of the Massive QED, describing a fermion with mass and charge int…
The g-2 in the neutral Electroweak model with cutoff: convergent expansion, RG and the Jackiw-Weinberg formula
Vieri Mastropietro, Michele Bianchessi
The prediction of the anomalous gyromagnetic factor of the electron, started with the evaluation of the electromagnetic contribution by Schwinger (1948) and of the weak contributio…
Edge transport in Haldane-like models with quasi-periodic disorder
Fabrizio Caragiulo, Vieri Mastropietro, Marcello Porta
We consider Haldane-like topological insulators on the cylinder, in the presence of weak quasi-periodic disorder. We prove that, at large distances, the boundary correlations…
Non-trivial fixed point of a fermionic theory, II. Anomalous exponent and scaling operators
Alessandro Giuliani, Vieri Mastropietro, Slava Rychkov +1
We consider the Renormalization Group (RG) fixed-point theory associated with a fermionic model in with fractional kinetic term, whose scaling dimension is fixed…
Response functions of many-body condensed matter systems
Marcello Porta, Vieri Mastropietro, Alessandro Giuliani
We discuss rigorous results about the response functions of gapped and gapless interacting fermionic lattice models, relevant for the study of transport in condensed matter physics…
Universality in the 2d quasi-periodic Ising model and Harris-Luck irrelevance
Matteo Gallone, Vieri Mastropietro
We prove that in the 2d Ising Model with a weak bidimensional quasi-periodic disorder in the interaction, the critical behavior is the same as in the non-disordered case, that is t…
