Annals of Mathematics, SECOND SERIES, Vol. 181, No. 3 (May, 2015), pp. 1087-1138 (52 pages) We rigorously prove the existence and the conformal invariance of scaling limits of the magnetization and ...

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 ...

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 ...
