To establish a unified framework for studying both discrete and continuous coupling distributions, we introduce the binomial spin glass, a class of models where the couplings are sums of m identically distributed Bernoulli random variables. In the continuum limit m→∞, the class reduces to one with Gaussian couplings, while m=1 corresponds to the ±J spin glass. We demonstrate that for short-range Ising models on d-dimensional hypercubic lattices the ground-state entropy density for N spins is…

The Stochastic Replica Approach to Machine Learning: Stability and Parameter Optimization
We introduce a statistical physics inspired supervised machine learning algorithm for classification and regression problems. The method is based on the invariances or stability of predicted results


Domain-wall excitations in the two-dimensional Ising spin glass
The Ising spin glass in two dimensions exhibits rich behavior with subtle differences in the scaling for different coupling distributions. We use recently developed mappings to graph-theoretic

Abstract: We present a simple strategy in order to show the existence and uniqueness of the infinite volume limit of thermodynamic quantities, for a large class of mean field disordered models, as

There is no hidden order pattern for spin glasses at all T less than T(C), the ordered-phase spin correlations being chaotic functions of spin separation at fixed temperature or of temperature at scale lengths L greater than (T delta T) exp -1/zeta.
Stiffness exponents for lattice spin glasses in dimensions $\mathsf{d = 3,\ldots,6}$
Abstract.The stiffness exponents in the glass phase for lattice spin glasses in dimensions $d = 3,\ldots,6$ are determined. To this end, we consider bond-diluted lattices near the T = 0 glass
Critical thermodynamics of the two-dimensional +/-J Ising spin glass.
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).
Robust Topological Degeneracy of Classical Theories
We challenge the hypothesis that the ground states of a physical system whose degeneracy depends on topology must necessarily realize topological quantum order and display non-local entanglement. To

An exact integer algorithm to compute the partition function of a two-dimensional ±J Ising spin glass given a set of quenched random bonds is described and the density of states is returned as a function of energy.
Are There Incongruent Ground States in 2D Edwards–Anderson Spin Glasses?
Abstract: We present a detailed proof of a previously announced result [1] supporting the absence of multiple (incongruent) ground state pairs for 2D Edwards–Anderson spin glasses (with zero external
On the computational complexity of Ising spin glass models
In a spin glass with Ising spins, the problems of computing the magnetic partition function and finding a ground state are studied and are shown to belong to the class of NP-hard problems, both in the two-dimensional case within a magnetic field, and in the three-dimensional cases.
Theory of spin glasses
A new theory of the class of dilute magnetic alloys, called the spin glasses, is proposed which offers a simple explanation of the cusp found experimentally in the susceptibility. The argument is
