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.
متن کاملPhase transitions in the three-state Ising spin-glass model with finite connectivity.
The statistical mechanics of a two-state Ising spin-glass model with finite random connectivity, in which each site is connected to a finite number of other sites, is extended in this work within the replica technique to study the phase transitions in the three-state Ghatak-Sherrington (or random Blume-Capel) model of a spin glass with a crystal-field term. The replica symmetry ansatz for the o...
متن کاملDynamical quantum phase transitions in the transverse-field Ising model.
A phase transition indicates a sudden change in the properties of a large system. For temperature-driven phase transitions this is related to nonanalytic behavior of the free energy density at the critical temperature: The knowledge of the free energy density in one phase is insufficient to predict the properties of the other phase. In this Letter we show that a close analogue of this behavior ...
متن کاملCritical Point Phenomena and Phase Transitions in the Ising Model
A Monte Carlo simulation of the Ising Model, a simplified model for studying the behavior of magnetic materials at various temperatures, was constructed. This model illustrated the transition between magnetic and non-magnetic phases as temperature is increased, and showed critical-point behavior at the transition. A general system for studying the behavior of many different configurations of pa...
