Researchers accurately replicate the predictions of 1D random-field Ising model in an artificial spin ice.

In this paper we start a systematic study of quantum field theory on random trees. Using precise probability estimates their Galton–Watson branches and multiscale analysis, establish the general power counting averaged Feynman amplitudes check that they behave indeed as living an effective space dimension 4/3, spectral “just renormalizable” case prove convergence amplitude any completely conver...
