Nonperturbative Chiral Anomaly Cancellation and Irrelevant Operators
Michele Bianchessi, Vieri Mastropietro, Marcello Porta
The Chiral anomaly cancellation is perturbatively well understood but its nonperturbative validity in presence of a lattice has remained unproven. We provide a rigorous nonperturba…
Large scale dynamical response of interacting Fermi systems
Marcello Porta, Giuseppe Scola, Harman Preet Singh
We consider the dynamics of a class of weakly interacting, gapless fermionic systems, in presence of small external perturbations slowly varying in space and in time. We consi…
Large Scale Response of Gapless and Quasi- Systems
Marcello Porta, Harman Preet Singh
We consider the transport properties of non-interacting, gapless one-dimensional quantum systems and of the edge modes of two-dimensional topological insulators, in the presence of…
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…
Universality of conductivity in interacting graphene
A. Giuliani, V. Mastropietro, M. Porta
The Hubbard model on the honeycomb lattice describes charge carriers in graphene with short range interactions. While the interaction modifies several physical quantities, like the…
