Dynamic Entanglement Evolution of Multi-Qubits Systems

Autor: N S Ananikian, Hrachya Lazaryan, Mikayel Nalbandyan

Publikováno v: Journal of Physics: Conference Series. 826:012024

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.

Singularities at a dense set of temperature singularities in the Husimi tree

Autor: N. S. Ananikian, A. E. Alahverdian, S. K. Dallakian

Publikováno v: Physical Review E. 57:2452-2454

We investigate complex temperature singularities of the three-site interacting Ising model on the Husimi tree in the presentce of magnetic field. We show that at certain magnetic field these singularities lie at a dense set and as a consequence the p

Publikováno v: Physical review letters. 97(4)

Diffusive Radiation is a new type of radiation predicted to occur in randomly inhomogeneous media due to the multiple scattering of pseudophotons. This theoretical effect is now observed experimentally. The radiation is generated by the passage of el

[Calculation of parameters of the phenomenological theory of helix-coil transition in polypeptides based on a microscopic model]

Autor: Sh A, Aĭrian, N S, Ananikian, V F, Morozov

Publikováno v: Biofizika. 32(3)

An expression for the partition function of the model including only two parameters-U (energy of hydrogen bond) and Q (the number of conformations of the repeating unit) with Hamiltonian is obtained. This expression has the form of algebraic series w
