The conductivity matrix at the topological phase transition
Simone Fabbri, Giovanna Marcelli, Alessandro Giuliani
For a general class of two-dimensional non-interacting semi-metallic electron systems on a lattice, we derive an explicit formula for the whole conductivity matrix, by using Euclid…
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…
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…
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…
Low-Temperature Spin-Wave Approximation for the Heisenberg Ferromagnet
M. Correggi, A. Giuliani, R. Seiringer
We study the low temperature thermodynamics of the quantum Heisenberg ferromagnet in three dimension for any value of the spin . We report on a rigorous proof of the…
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…
