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.…
Entanglement study of the 1D Ising model with Added Dzyaloshinsky-Moriya interaction
Javad Vahedi, Mohammad Reza Soltani, Saeed Mahdavifar
We have studied occurrence of quantum phase transition in the one-dimensional spin-1/2 Ising model with added Dzyaloshinsky-Moriya (DM) interaction from bi- partite and multi-parti…
Concurrence and entanglement entropy in a dimerized spin-1/2 two-leg ladder
Somayyeh Nemati, Saeed Mahdavifar, Saeed Batebi
We consider the isotropic spin-1/2 two-leg ladders with the dominant spatially modulated rung exchanges. We study the effect of a uniform magnetic field on the ground state phase d…
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…
1D Frustrated Ferromagnetic Model with Added Dzyaloshinskii-Moriya Interaction
Javad Vahedi, Saeed Mahdavifar
The one-dimensional (1D) isotropic frustrated ferromagnetic spin-1/2 model is considered. Classical and quantum effects of adding a Dzyaloshinskii-Moriya (DM) interaction on the gr…
Effects of a space modulation on the behavior of a 1D alternating Heisenberg spin-1/2 model
Saeed Mahdavifar, Jahanfar Abouie
The effects of a magnetic field () and a space modulation () on the magnetic properties of a one dimensional antiferromagnetic-ferromagnetic Heisenberg spin-1/2 model have be…
