Comparison of Ising spin glass noise to flux and inductance noise in SQUIDs
Z Chen, CC Yu - Physical review letters, 2010 - APS
Recent experiments implicate spins on the surface of metals as the source of flux and
inductance noise in SQUIDs. We present Monte Carlo simulations of 2D and 3D Ising spin …

The phase diagram of Lévy spin glasses
We study a fully connected spin-glass model in which the coupling strengths are drawn from
a Lévy distribution. In this model each spin can be seen as interacting through a finite …
