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 ...
We derive the exact ground-state energy of the one-dimensional Ising model in random fields taking values h, 0 and -h with general probabilities. The random-field Ising model on a ladder is also analyzed by showing its equivalence to the random-field Ising chain with field values +/-h and...
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 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...

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, ...
This development will strengthen the position of Europe, the Netherlands and our partners in a global emerging value chain,” said Kees Buijsrogge, Director TNO Space. Rob Postma, Managing Director of Airbus Netherlands B.V.: “This contract marks the beginning of the development of a pr...
The area law for entanglement provides one of the most important connections between information theory and quantum many-body physics. It is not only related to the universality of quantum phases, but also to efficient numerical simulations in the ground state. Various numerical observations have led...
