Quantum correlation in the spin-1/2 two-dimensional honeycomb-bilayer lattice antiferromagnet and spin-1 honeycomb-bilayer two-dimensional XY model is studied. For the spin-1 XY model, the calculations were performed taking into account the next-near

In this paper, we lock the focus in effect of $\mathcal {P}\mathcal {T}$ -symmetric operation on the dynamics of concurrence and the first-order coherence for Heisenberg XY model. We discover the complementarity between concurrence and the first-orde

The accuracy and feasibility of the traditional XY model of transformer oil–paper insulation system are disputable since it ignored the effect of non‐uniform aging and conductance on dielectric response property. Given this issue, this work attem

The family of monolayer two-dimensional (2D) materials hosts a wide range of interesting phenomena, including superconductivity, charge density waves, topological states and ferromagnetism, but direct evidence for antiferromagnetism in the monolayer

We propose a quantum Otto cycle in a two spin-$1/2$ anisotropic XY model in a transverse external magnetic field. We first characterize the parameter regime that the working medium operates as an engine in the adiabatic regime. Then, we consider fini

A Monte Carlo simulation of the nonequilibrium critical behavior is carried out for the two-dimensional structurally disordered XY model during its evolution from a high-temperature initial state. The features of the effect of structural disorder on

Ideal two-dimensional (2D) Heisenberg magnets lack long range magnetic order. However, the XY model with spins confined to a plane shows a topological phase transition at a finite temperature corresponding to binding and unbinding of vortices. Experi
