By extending a proof of a physically important behavior in one-dimensional quantum spin systems to higher dimensions, a RIKEN ...

Combinatorial optimization problems are at the root of many industrial processes and solving them is key to a more sustainable and efficient future. Ising machines can solve certain combinatorial ...

The central selling point of qubit-based quantum processors is that they can supposedly solve certain types of tasks much faster than a classical computer. This comes however with the major ...

This is the last in a series of three papers on the history of the Lenz-Ising model from 1920 to the early 1970s. In the first paper, I studied the invention of the model in the 1920s, while in the ...

These models differ by the constrains given to the orientation of the electron's spins (arrows). If all spins are aligned in one direction, the material becomes a ferromagnet. Below the magnetic ...

In previous papers (1976), (1977a), (1979) limit theorems were obtained for the classical Ising model, and these provided the basis for asymptotic inference. The present paper extends these results to ...
