We consider four atoms coupled to each other by Heisenberg like interactions in an external field of electromagnetic radiation. We prepare Schrodinger cat state using the STIRAP and f-STIRAP techniques.

We study physical properties of the symmetric diamond chain with delocalized interstitial spins. We derive an exact solution of the model and characterize the phases of the system at zero temperature. On the basis of this solution, we examine its mag

We present the results of magnetic properties and entanglement of the distorted diamond chain model for azurite using pure quantum exchange interactions. The magnetic properties and concurrence as a measure of pairwise thermal entanglement have been

The exact solution of the distorted Ising-Hubbard model for a diamond chain is obtained by means of transfer matrix method. Based on this solution the magnetic, thermal and concurrence properties of the system are studied. We discuss in detail the gr

Using Heisenberg model with two-, three- and four-site exchange interactions, by means of variational mean-feld like treatment based on Gibbs-Bogoliubov inequality the magnetic properties and concurrence (measure of pairwise thermal entanglement) on
