Interface evolution in the two-dimensional quantum Ising model
Georgios Kampanis, Marianna Sorba, Gesualdo Delfino
The paper analytically studies how an interface between the two degenerate ground states of the two‑dimensional quantum Ising model evolves over time after a generic initial interp…
Criticality in the disordered -color Ashkin-Teller model
Youssef Makoudi, Gesualdo Delfino
The -color Ashkin-Teller model corresponds to Ising models coupled by four-spin interactions. We consider the two-dimensional case in presence of quenched disorder and use s…
On the nature of the spin glass transition
Gesualdo Delfino
We recently showed that the two-dimensional Ising spin glass allows for a line of renormalization group fixed points which explains properties observed in numerical studies. We obs…
Quantum quenches with long range interactions
Marianna Sorba, Nicolò Defenu, Gesualdo Delfino
We extend the theory of quantum quenches to the case of -dimensional homogeneous systems with long range interactions. This is achieved treating the long range interactions as s…
Exact results for spin glass criticality
Gesualdo Delfino
In recent years scale invariant scattering theory provided the first exact access to the magnetic critical properties of two-dimensional statistical systems with quenched disorder.…
Critical exponents at the Nishimori point
Gesualdo Delfino
The Nishimori point of the random bond Ising model is a prototype of renormalization group fixed points with strong disorder. We show that the exact correlation length and crossove…
