Spin squeezing: Thermal behavior and distribution on excited states
Saeed Mahdavifar, Hadi Cheraghi, Kourosh Afrousheh
We investigate the spin-squeezing behavior under thermal effects in a one-dimensional transverse field XY model with spin-1/2. The exact solution of the model helps us to compute t…

Spin-1/2 XX chains with modulated Gamma interaction
M. Abbasi, S. Mahdavifar, M. Motamedifar
We study the spin-1/2 XX chain with a modulated Gamma interaction (GI), which results from the superposition of uniform and staggered Gamma terms. We diagonalize the Hamiltonian of…
