A remark on the notion of robust phase transitions

Magnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice

Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization,  internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.

بررسی اثر برخی افزودنی ها بر انتقالات فازی و رفتار حرارتی آمونیوم نیترات

Ammonium nitrate (AN) is widely used in fertilizers, civilian explosives and military explosives. Due to crystalline phase transitions and density changes of AN in the ambient conditions, its usage as oxidizer in solid propellants has some limitations as compared to ammonium perchlorate (AP). Several methods have been introduced to overcome these problems. In the present paper, the phase transi...

GCMC Glauber dynamics study for structural transitions in YBCOx (0<x<1), HTc system

We have chosen an Ising ASYNNNI (ASYmmetric Next Nearest Neighbor Interaction)   model under a grand canonical regime to investigate structural phase transition from a high symmetric tetragonal (Tet) to a low symmetric orthorhombic in YBa2Cu3O6+x , 0<x<1,  HTc system. Ordering process for absorbed oxygens from an external gas bath into the basal plane of the layered system is studied by Monte C...

نقش دینامیک شبکه در ابررسانای La2-xBaxCuO4 به روش DFT

Electron-phonon coupling parameters are calculated for La2-x BaxCuO4 cuprate superconductor in a wide range of dopings, from undoped to overdoped compounds. In this study we aim to study the quality of such calculations based on DFT method so, the results of σ GGA+U electronic structure calculations are also investigated. The obtained value for electron-phonon coupling is in the same order of p...
