Quantum phase transitions in the Kondo-necklace model: Perturbative continuous unitary transformation approach
S. Hemmatiyan, M. Rahimi Movassagh, N. Ghassemi +3
The Kondo-necklace model can describe magnetic low-energy limit of strongly correlated heavy fermion materials. There exist multiple energy scales in this model corresponding to ea…
Dzyaloshinskii-Moriya Interaction and Anisotropy effects on the Entanglement of Heisenberg Model
M. Kargarian, R. Jafari, A. Langari
In this paper the the effect of Dzyaloshinskii-Moriya interaction and anisotropy on the Entanglement of Heisenberg chain has been studied. While the anisotropy suppress the entangl…
Interacting Anyonic Fermions in a Two-Body Color Code Model
H. Bombin, M. Kargarian, M. A. Martin-Delgado
We introduce a two-body quantum Hamiltonian model of spin-1/2 on a 2D spatial lattice with exact topological degeneracy in all coupling regimes. There exists a gapped phase in whic…
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…
