An exact algorithm is used to compute the degeneracies of the excited states of the bimodal Ising spin glass in two dimensions. It is found that the specific heat at arbitrary low temperature is not a self-averaging quantity and has a distribution that is neither normal nor lognormal. Nevertheless, it is possible to estimate the most likely value and this is found to scale as L3T-2 exp (−4J/kT), for a L×L lattice. Our analysis also explains, for the first time, why a correlation length ξ~exp…

Replica Cluster Variational Method
TLDR
The physical interpretation of the beliefs in the replica-symmetric phase as disorder distributions of the local Hamiltonian is provided and indeed they cannot be represented as populations in the spin-glass phase at variance with the Bethe approximation.

Critical thermodynamics of the two-dimensional +/-J Ising spin glass.
TLDR
The exact partition function of 2d Ising spin glasses with binary couplings is computed, finding that the low temperature specific heat density scales as exp(-2J/T), corresponding to an "effective" gap of size 2J; in addition, an associated crossover length scale grows as exp( J/T).

Strong universality and algebraic scaling in two-dimensional Ising spin glasses.
TLDR
The scaling at low but nonzero temperatures is considered and numerical evidence that eta approximately equal 0 and nu approximately equal 3.5 in all cases suggests a unique universality class, suggesting a real space renormalization group approach.
