Non-Markovian dynamics in the extended cluster spin-1/2 XX chain
M. Mahmoudi, M. R. Soltani, T. Mohammad Ali Zadeh +1
We study the dynamics of entanglement in the extended cluster spin-1/2 XX chain, equivalent to a 1D spin-1/2 XX model with three-spin interaction (TSI). Selecting the nearest neigh…
Solving Abel integral equations of first kind via fractional calculus
Salman Jahanshahi, Esmail Babolian, Delfim F. M. Torres +1
We give a new method for numerically solving Abel integral equations of first kind. An estimation for the error is obtained. The method is based on approximations of fractional int…
Quantum correlations in the 1D spin-1/2 Ising model with added Dzyaloshinskii-Moriya interaction
M. R. Soltani, J. Vahedi, S. Mahdavifar
We have considered the 1D spin-1/2 Ising model with added Dzyaloshinskii-Moriya (DM) interaction and presence of a uniform magnetic field. Using the mean-field fermionization appro…
Investigation of frustrated and dimerized classical Heisenberg chains
J. Vahedi, S. Mahdavifar, M. R. Soltani +1
We have considered the 1D dimerized frustrated antiferromagnetic (ferromagnetic) Heisenberg model with arbitrary spin . The exact classical magnetic phase diagram at zero temper…
Improving Security Levels of IEEE 802.16e Authentication By Diffie-Hellman Method
Mohammad Zabihi, Ramin Shaghaghi, Mohammad Esmail kalantari
In this paper, we proposed an authentication method according to Diffie-Hellman. First, we introduce different methods for authentication in IEEE.802.16 then we proposed an authent…
