Ground State Excitations and Energy Fluctuations in Short-Range Spin Glasses
C. M. Newman, D. L. Stein
We study the stability of ground states in the Edwards-Anderson Ising spin glass in dimensions two and higher against perturbations of a single coupling. After reviewing the concep…

Zero Temperature Dynamics of Ising Systems on Hypercubes
Ruixin Chen, Jonathan Machta, Charles M. Newman +1
We study the zero-temperature Glauber dynamics of homogeneous Ising ferromagnets on hypercubes, as their dimension d varies. We investigate the asymptotic (d goes to infinity and t…

Critical Droplets and Replica Symmetry Breaking
C. M. Newman, D. L. Stein
We show that the notion of critical droplets is central to an understanding of the nature of ground states in the Edwards-Anderson Ising model of a spin glass in arbitrary dimensio…
