finite range interactionssimple spin configurations/ A7510H Ising and other classical spin models (magnetism)It is shown that the ground state of an Ising chain with interaction of range three is essentially a repetition of one simple spin configuration, out of seven possible configurations....
We show that the Svetlichny function evaluated using the simulated ground state of the Ising chain violates the N- party local-realistic bound that, even for a short chain, is very close to the quantum critical point defined in the thermodynamic limit N R '. By exploiting the analytical ...
When trained on random Hamiltonians of nearest-neighbour spin glasses, the RL agent is able to control the SA process for other Hamiltonians, reaching the ground state with a higher probability than a simple linear annealing schedule. Furthermore, the scaling performance (with respect to system ...

The model is a special limiting case of the random field Ising chain. We calculate (1) the energy and density of the ground state as well as the local energy-density correlation and (2) the pair correlation function. The latter calculation gives access to all higher order correlations. The...
AF chain Fig. 1. An AF chain stacked state of the AF Ising model, where each AF chain is indicated by arrows. Open and closed circles represent the up- and the down-spins, respectively. Solid lines represent bonds with AF configuration, while dashed lines represent bonds with ferromagneti...
In both cases of ferromagnetic and antiferromagnetic nearest-neighbour intrachain interactions, the ground state phase diagrams are obtained exactly for the spin S=1 axial next-nearest-neighbour Ising (ANNNI) model with the single-ion anisotropy, - DS, by using the fundamental spin arrangement (...
The thermodynamic properties of Cu(NO3)2·2.5H2O are compared with calculated properties of the one-dimensional alternating Heisenberg antiferromagnet as described by the Hamiltonian: H=-2JΣn(S⃗2n·S⃗2n+1+αS⃗2n·S⃗2n-1)-gμBΣnH⃗·S⃗n, with α=0.27 and J/k=-2.6 K....
Regarding the economic consequences of security breaches, the authors state that indirect losses can have a long, negative impact on the cus- tomer base, supplier partners, financial market, banks and business relationships. Such losses include damage to the reputation of the organisation, ...
Deterministic models are powerful tools, based on physical and/or chemical properties of the environment to first copy then predict an aquifer’s steady state and its evolution. Yet models are a simplification of the real world, and they come with a level of uncertainty, which depends on severa...
