A possible tricritical line in Ni(NO3)2 · 2H2O
(1987-04-02)
We obtain the behaviour of the critical (possibly tricritical) point for metamagnetic Ni(NO3)2·2H2O as a function of several applied hydrostatic pressures up to 11 kbar. The obtained line of possible tricritical points ...

Tricritical wetting in the two-dimensional Ising magnet due to the presence of localized non-magnetic impurities
(IOP Publishing, 2016-02)
Fixed vacancies (non-magnetic impurities) are placed along the centre of Ising strips in order to study the wetting behaviour in this confined system, by means of numerical simulations analysed with the aid of finite size ...
First-order and tricritical wetting transitions in the two-dimensional Ising model caused by interfacial pinning at a defect line
(American Physical Society, 2014-08)
We present a study of the critical behavior of the Blume-Capel model with three spin states (S=±1,0) confined between parallel walls separated by a distance L where competitive surface magnetic fields act. By properly ...
Critical phenomena in quasi-two-dimensional vibrated granular systems
(Amer Physical SOC, 2018)
The critical phenomena associated to the liquid-to-solid transition of quasi-two-dimensional vibrated granular systems is studied using molecular dynamics simulations of the inelastic hard sphere model. The critical ...
The van Hemmen model and effect of random crystalline anisotropy field
(Elsevier B.V., 2016-01-15)
In this work, we have presented the generalized phase diagrams of the van Hemmen model for spin S=1 in the presence of an anisotropic term of random crystalline field. In order to study the critical behavior of the phase ...
Integrable aspects of the scaling q-state Potts models II: finite-size effects
(Elsevier B.V., 2003-06-30)
We continue our discussion of the q-state Potts models for q less than or equal to 4, in the scaling regimes close to their critical and tricritical points. In a previous paper, the spectrum and full S-matrix of the models ...
