Concurrence distribution in excited states of the 1D spin-1/2 transverse field XY model: two different regions
S. Mahdavifar, Z. Balador, M. R. Soltani
We investigate the variation of concurrence in a spin-1/2 transverse field XY chain system in an excited state. Initially, we precisely solve the eigenvalue problem of the system H…
Exploring quantum coherence, spin squeezing and entanglement in an extended spin-1/2 XX Chain
S. Mahdavifar, F. Khastehdel Fumani, B. Haghdoost +1
In this study, we explore the ground state phase diagram of the spin-1/2 XX chain model, which features type three-spin interactions (TSI). This model, while seemingly si…
Quantum correlations in the frustrated XY model on the honeycomb lattice
Sahar Satoori, Saeed Mahdavifar, Javad Vahedi
We consider the spin- XY frustrated antiferromagnetic Heisenberg honeycomb model. There is an unclear intermediate region in the ground state phase diagram of the model. The m…
Entanglement and quantum correlations in the XX spin- honeycomb lattice
S. Satoori, S. Mahdavifar, J. Vahedi
The ground state phase diagram of the dimerized spin-1/2 XX honeycomb model in presence of a transverse magnetic field (TF) is known. With the absence of the magnetic field, two qu…
Amplifying quantum correlations with quench dynamics in a quantum spin chain: Steady-states versus ground-states
Sasan Kheiri, Hadi Cheraghi, Saeed Mahdavifar
We analyze the behavior of steady-state quantum correlations (QCs) in the spin-1/2 transverse field XY chains analytically, in terms of quench dynamics at zero-temperature. We show…
Achieving spin-squeezed states by quench dynamics in a quantum chain
Hadi Cheraghi, Saeed Mahdavifar, Henrik Johannesson
We study the time evolution of spin squeezing in the one-dimensional spin-1/2 XY model subject to a sudden quantum quench of a transverse magnetic field. The initial state is selec…
