The multipartite nonlocality of finite and infinite transverse‐field Ising model is investigated. For the finite chain, the exact diagonalization method is used to study the multipartite nonlocality at zero and
We study the effect of quantum fluctuations by means of a transverse magnetic field ( 螕 ) on the antiferromagnetic J 1 - J 2 Ising model on the checkerboard lattice, the two dimensional version of the pyrochlore lattice. The zero-temperature phase diagram of the model has been obtained by ...

The curvature was enhanced by tapering the pole gap towards the outside to produce a constant field gradient both across the aperture and around the machine. Horizontal focusing was provided by the effect of an imbalance between the force due ...
The model consists of Pauli spins arranged on a simple square or cubic lattice, experiencing nearest-neighbor interactions through their x components and subjectto a transverse field in the z direction of strength u03bb.

We derive closed-form expressions for this energy gap between the different parity subspaces and analyze its behavior and dependence on the system size in the various regimes of the applied field. Finally, we suggest an expression for the correlation length of such a model that is consistent ...
The uncharged sector of the Z (2) lattice gauge model in two spatial dimensions is analyzed within variational correlated basis functions (CBF) theory applied to the dual Ising-spin model with a transverse magnetic field. The CBF analysis of the associated ground and excited states is conducted...
We consider the quantum spin-1/2 Ising chain in a uniform transverse magnetic field, with an aperiodic sequence of ferromagnetic exchange couplings. This system is a limiting anisotropic case of the classical two-dimensional Ising model with an arbitrary layered modulation. Its formal solution via ...
