Phase transitions and entanglement properties in spin-1 Heisenberg clusters with single-ion anisotropy
V S Abgaryan, N S Ananikian, L N Ananikyan +1
The incipient quantum phase transitions of relevance to nonzero fluctuations and entanglement in Heisenberg clusters are studied in this paper by exploiting negativity as a measure…
Magnetization and Lyapunov exponents on a kagome chain with multi-site exchange interaction
N. Ananikian, L. Ananikyan, R. Artuso +1
The Ising approximation of the Heisenberg model in a strong magnetic field, with two, three and six spin exchange interactions is studied on a kagome chain. The kagome chain can be…
Arnold Tongues and Feigenbaum Exponents of the Rational Mapping for Q-state Potts Model on Recursive Lattice: Q<2
L. N. Ananikyan, N. S. Ananikian, L. A. Chakhmakhchyan
We considered Q-state Potts model on Bethe lattice in presence of external magnetic field for Q<2 by means of recursion relation technique. This allows to study the phase transitio…
Spin Effects in Quantum Chromodynamics and Recurrence Lattices with Multi-Site Exchanges
Lev Ananikyan
In this thesis, we consider some spin effects in QCD and recurrence lattices with multi-site exchanges. Main topic of our manuscript are critical phenomena in spin systems defined…
