Signature of the quantum critical point on the witness of the non-Markovianity and the entanglement in spin-1/2 chain
Z. Saghafi, S. Samadi Rezaei, P. Azizi +2
A thermodynamic limit chain of spin-1/2 particles with XX and three-spin interactions (TSI) is considered. Using the fermionization technique, the Hamiltonian of the chain with per…
Markovian and Non-Markovian dynamics in the one-dimensional transverse-field XY model
Z. Saghafi, S. Mahdavifar, E. Hosseini Lapasar
We consider an anisotropic spin-1/2 XY Heisenberg chain in the presence of a transverse magnetic field. Selecting the nearest neighbor pair spins as an open quantum system, the res…
Focusing on the dynamics of the entanglement in spin junction
Z. Saghafi, Z. Shadman, E. Hosseini Lapasar +1
We study the dynamics of entanglement in the one-dimensional spin-1/2 XY model in the presence of a transverse magnetic field. A pair of spins are considered as an open quantum sys…
Markovian and non-Markovian dynamics from probability amplitudes perspective
Z. Saghafi, S. Samadi Rezaei, E. Hosseini Lapasar +1
One-spin and two-spin in a thermodynamic limit spin-1/2 chain as open quantum systems are considered. The dynamics of system is generated by XX Heisenberg interaction and three-spi…
Quantum Chaos in the Heisenberg Spin Chain: the Effect of Dzyaloshinskii-Moriya Interaction
J. Vahedi, A. Ashouri, S. Mahdavifar
Using one-dimensional spin-1/2 systems as prototypes of quantum many-body systems, we study the emergence of quantum chaos. The main purpose of this work is to answer the following…
