A universal emulator for planar Ising lattices
Riccardo Ben Alì Zinati, Alessandro Codello
We introduce the notion of an Ising emulator for two-dimensional Ising models: flat, unit-edge-length lattices can be represented as site- or bond-diluted supercells of a single ho…

The phase boundary of the random site Ising model
Riccardo Ben Alì Zinati, Giacomo Gori, Alessandro Codello
We introduce a new approach to disordered two-dimensional Ising models based on the extension of the combinatorial solution to randomized supercells. Applying it to the site-dilute…

Critical Temperature(s) of Sierpinski Carpet(s)
Riccardo Ben Alì Zinati, Giacomo Gori, Alessandro Codello
We present a key algorithmic improvement to the generalized combinatorial Feynman--Vdovichenko method for calculating the critical temperature of the Ising model on Sierpinski carp…
