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…
Kagome Approximation for 3He on Husimi Lattice with Two- and Three-Site Exchange Interactions
N. Ananikian, V. Hovhannisyan, H. Lazaryan
The Ising approximation of the Heisenberg model in a strong magnetic field, with two-, and three-spin exchange interactions are studied on a Husimi lattice. This model can be consi…
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…
