Nematic order in a simple-cubic lattice-spin model with full-ranged dipolar interactions
Hassan Chamati, Silvano Romano
In a previous paper [Phys. Rev. E 90, 022506 (2014)], we had studied thermodynamic and structural properties of a three-dimensional simple-cubic lattice model with dipolar-like int…
Classical lattice spin models involving singular interactions isotropic in spin space
Hassan Chamati, Silvano Romano
We address here a few classical lattice--spin models, involving component unit vectors (), associated with a dimensional lattice , and interact…
Nematic order by thermal disorder in a three-dimensional lattice-spin model with dipolar-like interactions
H. Chamati, S. Romano
At low temperatures, some lattice spin models with simple ferromagnetic or antiferromagnetic interactions (for example nearest-neighbour interaction being isotropic in spin space o…
Comment on the paper by Y.Komura and Y.Okabe [arXiv:1011.3321]
Aernout C. D. van Enter, Silvano Romano, Valentin A. Zagrebnov
We point out that the claim of strong universality in the paper J.Phys. A 44, 015002, arXiv:1011.3321 is incorrect, as it contradicts known rigorous results.
Interaction anisotropy and random impurities effects on the critical behaviour of ferromagnets
H Chamati, S Romano
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only…
First order phase transitions in classical lattice gas spin models
H Chamati, S Romano
The present paper considers some classical ferromagnetic lattice--gas models, consisting of particles that carry --component spins () and associated with a --dimension…
