رهیافت معادلات جریان در مدل آیزینگ کوانتمی یک بعدی
One dimensional quantum Ising model with nearest neighbor interaction in transverse magnetic field is one of the simplest spin models which undergo quantum phase transition. This model has been precisely solved using different methods. In this paper, we solve this model in uniform magnetic field -Jgσxn precisely using a new method called Continuous Unitary Transformations (CUT) or flow equation...
متن کاملMagnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملSpin waves and Quantum Phase Transitions in the near 1D Ising system CoCl2∙D2O Bachelor Project
In this project we have studied quantum phase transitions and spin waves as well as the magnetic ordering temperature for the CoCl2· 2D2O crystal using neutron scattering and susceptibility measurements, respectively. The crystal is chosen for its Ising like behaviour. We used the FLEXX instrument at BENSC to measure spin waves and the quantum critical point. We found the critical field to be 1...
متن کاملMagnetic 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 کاملQuantum spin glass in anisotropic dipolar systems
The spin-glass phase in the LiHoxY1−xF4 compound is considered. At zero transverse field this system is well described by the classical Ising model. At finite transverse field deviations from the transverse field quantum Ising model are significant, and one must take properly into account the hyperfine interactions, the off-diagonal terms in the dipolar interactions, and details of the full J =...
