Phase Diagram of spin 1/2 XXZ Model With Dzyaloshinskii-Moriya Interaction
R. Jafari, A. Langari
We have studied the phase diagram of the one dimensional XXZ model with Dzyaloshinskii-Moriya (DM) interaction. We have applied the quantum renormalization group (QRG) approach to…
Phase Diagram and Entanglement of Ising Model With Dzyaloshinskii-Moriya Interaction
R. Jafari, M. Kargarian, A. Langari +1
We have studied the phase diagram and entanglement of the one dimensional Ising model with Dzyaloshinskii-Moriya (DM) interaction. We have applied the quantum renormalization group…
Green's function approach to quantum criticality in the anisotropic Kondo-necklace model
H. Rezania, A. Langari, P. Thalmeier
We have studied the quantum phase transition between the antiferromagnetic and spin liquid phase for the two dimensional anisotropic Kondo-necklace model. The bond operator formali…
Phase diagram of the one dimensional anisotropic Kondo-necklace model
S. Mahmoudian, A. Langari
The one dimensional anisotropic Kondo-necklace model has been studied by several methods. It is shown that a mean field approach fails to gain the correct phase diagram for the Isi…
Thermodynamic Properties of XXZ model in a Transverse Field
M. Siahatgar, A. Langari
We have numerically studied the thermodynamic properties of the spin 1/2 XXZ chain in the presence of a transverse (non commuting) magnetic field. The thermal, field dependence of…
The renormalization of entanglement in the anisotropic Heisenberg (XXZ) model
M. Kargarian, R. Jafari, A. Langari
We have applied our recent approach (Kargarian, et.al Phys. Rev. A 76, 60304 (R) (2007)) to study the quantum information properties of the anisotropic s=1/2 Heisenberg chain. We h…
