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…
Renormalization of concurrence: the application of quantum renormalization group to the quantum information systems
M. Kargarian, R. Jafari, A. Langari
We have combined the idea of renormalization group and quantum information theory. We have shown how the entanglement or concurrence evolve as the size of the system being large, i…
Dielectric Susceptibility and Heat Capacity of Ultra-Cold Glasses in Magnetic Field
Alireza Akbari, D. Bodea, A. Langari
Recent experiments demonstrated unexpected, even intriguing properties of certain glassy materials in magnetic field at low temperatures. We have studied the magnetic field depende…
Spin Ladder with Anisotropic Ferromagnetic Legs in a Transverse Magnetic Field
G. I. Japaridze, A. Langari, S. Mahdavifar
We study the ground state phase diagram of a two-leg spin ladder with anisotropic ferromagnetic leg couplings under the influence of a symmetry breaking transverse magnetic field b…
