Universality of the topological phase transition in the interacting Haldane model
Simone Fabbri, Alessandro Giuliani, Robin Reuvers
The Haldane model is a standard tight-binding model describing electrons hopping on a hexagonal lattice subject to a transverse, dipolar magnetic field. We consider its interacting…

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…

The scaling limit of boundary spin correlations in non-integrable Ising models
Giulia Cava, Alessandro Giuliani, Rafael Leon Greenblatt
We consider a class of non-integrable 2D Ising models obtained by perturbing the nearest-neighbor model via a weak, finite range potential which preserves translation and spin-flip…
