The magnetic properties and ground states of the geometry of the mixed spins S= 3∕ 2 and
σ= 2 Ising model on diamond-like decorated square have studied using the Monte Carlo …

A hybrid spin-electron system defined on a one-dimensional double-tetrahedral chain, in
which the localized Ising spin regularly alternates with two mobile electrons delocalized over …

Quasicritical exponents of one-dimensional models displaying a quasitransition at finite
temperatures are examined in detail. The quasitransition is characterized by intense sharp …

We find an exact map** from the generalized Ising models with many-spin interactions to
equivalent Boltzmann machines, ie, the models with only two-spin interactions between …

We consider the quasi-one dimensional spin-1 Ising–Heisenberg model with single-ion
anisotropy on a diamond chain. Due to the exact solution of the model, we constructed the …

Abstract We consider a spin-1/2 Ising-XYZ distorted diamond chain with the XYZ interaction
between the interstitial Heisenberg dimers, the nearest-neighbor Ising coupling between the …

Abstract The spin-1 Ising–Heisenberg diamond chain with the second-neighbor interaction
between nodal spins is rigorously solved using the transfer-matrix method. In particular …

The strongly correlated spin-electron system on a diamond chain containing localized Ising
spins on its nodal lattice sites and mobile electrons on its interstitial sites is exactly solved in …

We examine the general features of the noncommutativity of the magnetization operator and
Hamiltonian for small quantum spin clusters. The source of this noncommutativity can be a …

Abstract The spin-1 Ising–Heisenberg diamond chain in a magnetic field is exactly solved by
a rigorous treatment based on the transfer-matrix method. An exact ground-state phase …
