Ensemble dependence of the critical behavior of a system with long-range interaction and quenched randomness
Nir Schreiber, Reuven Cohen, Simi Haber
We propose a hybrid model governed by the Blume-Emery-Griffiths (BEG) Hamiltonian with a mean-field-like interaction, where the spins are randomly quenched such that some of them a…

Efficient covering of convex domains by congruent discs
Shai Gul, Reuven Cohen, Simi Haber
In this paper, we consider the problem of covering a plane region with unit discs. We present an improved upper bound and the first nontrivial lower bound on the number of discs ne…

Changeover phenomenon in randomly colored Potts models
Nir Schreiber, Reuven Cohen, Gideon Amir +1
A hybrid Potts model where a random concentration of the spins assume states and a random concentration of the spins assume states is introduced. It is know…
