Dynamics of Quantum Coherence and Quantum Fisher Information After Sudden Quench
R. Jafari, Alireza Akbari
The dynamics of relative entropy and -norm of coherence, as well as, the Wigner-Yanase-skew and quantum Fisher information are studied for a time-dependent coupled XY spin c…
Quench dynamics and zero-energy modes: the case of the Creutz model
R. Jafari, Henrik Johannesson, A. Langari +1
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in the Brillouin zone. Differently, in the Creutz model describing a system of spinle…
Dynamical quantum correlations after sudden quenches
Utkarsh Mishra, Hadi Cheraghi, Saeed Mahdavifar +2
We employ the mean-field approach in the fermionic picture of the spin-1/2 XXZ chain to investigate the dynamics of bipartite quantum discord and concurrence under sudden quenching…
Loschmidt Echo Revivals: Critical and Noncritical
R. Jafari, Henrik Johannesson
A quantum phase transition is generally thought to imprint distinctive characteristics on the nonequilibrium dynamics of a closed quantum system. Specifically, the Loschmidt echo a…
Three-Qubit Ground State and Thermal Entanglement of Model With Dzyaloshinskii-Moriya Interaction
R. Jafari, A. Langari
We have studied the symmetric and non-symmetric pairwise ground state and thermal entanglement in three-qubit anisotropic Heisenberg (XXZ) and Ising in a magnetic field models and…
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…
