Interface evolution in the two-dimensional quantum Ising model
Georgios Kampanis, Marianna Sorba, Gesualdo Delfino
We consider the unitary time evolution of an interface in the regime of spontaneously broken symmetry of the two-dimensional quantum Ising model. The interface is induced by an ini…

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…
