Quasitopological Lifshitz dilaton black brane
A. Bazrafshan, M. Ghanaatian, S. Rezaei +1
We construct a new class of -dimensional Lifshitz dilaton black brane solutions in the presence of the cubic quasitopological gravity for a flat boundary. The related action…

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 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…
