Theoretical investigation of the behavior of CuSe2O5 compound in high magnetic fields
Z. Saghafi, J. Jahangiri, S. Mahdavifar +2
Based on analytical and numerical approaches, we investigate thermodynamic properties of CuSe2O5 at high magnetic fields which is a candidate for the strong intra-chain interaction…
Quantum phase transition in a dimerized chain with hexamer distortion
Mahboobeh Shahri Naseri, George I. Japaridze, Saeed Mahdavifar +1
We consider the dimerized spin-1/2 Heisenberg chain with spin hexameric distortion of the exchange pattern and study the zero-temperature phase diagram in the parameter space $(J_{…
From fidelity to entanglement of entropy of the one-dimensional transverse-field quantum compass model
Mostafa Motamedifar, Somayyeh Nemati, Saeed Mahdavifar +1
We study fidelity and fidelity susceptibility by addition of entanglement of entropy in the one-dimensional quantum compass model in a transverse magnetic field numerically. The wh…
Magnetic properties of the spin Heisenberg chain with hexamer modulation of exchange
M. Shahri Naseri, G. I. Japaridze, S. Mahdavifar +1
We consider the spin-1/2 Heisenberg chain with alternating spin exchange %on even and odd sites in the presence of additional modulation of exchange on odd bonds with period three.…
The quantum compass chain in a transverse magnetic field
Mostafa Motamedifar, Saeed Mahdavifar, Saber Farjami Shayesteh
We study the magnetic behaviors of a spin-1/2 quantum compass chain (QCC) in a transverse magnetic field, by means of the analytical spinless fermion approach and numerical Lanczos…
