Ordered moment in the anisotropic and frustrated square lattice Heisenberg model
Burkhard Schmidt, Mohammad Siahatgar, Peter Thalmeier
The two-dimensional frustrated next nearest neighbor Heisenberg model on the square lattice is a prime example for a spin system where quantum fluctuations can either destroy or st…

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…

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…
