Measuring overlaps in mesoscopic spin glasses via conductance fluctuations
arXiv:0710.3442 · doi:10.1103/PhysRevLett.100.057207
Abstract
We consider the electonic transport in a mesoscopic metallic spin glasses. We show that the distribution of overlaps between spin configurations can be inferred from the reduction of the conductance fluctuations by the magnetic impurities. Using this property, we propose new experimental protocols to probe spin glasses directly through their overlaps.
