As Phil Anderson noted long ago, frustration can be generally defined by measuring the fluctuations in the coupling energy across a plane boundary between two large blocks of material. Since that time, a number of groups have studied the free energy fluctuations between (putative) distinct spin glass thermodynamic states. While upper bounds on such fluctuations have been obtained, useful lower bounds have been more difficult to derive. I present a history of these efforts, and briefly discuss…

A Relation Between Disorder Chaos and Incongruent States in Spin Glasses on $${\mathbb{Z}^d}$$Zd
We derive lower bounds for the variance of the difference of energies between incongruent ground states, i.e., states with edge overlaps strictly less than one, of the Edwards–Anderson model on

In the introduction to this volume, we discuss some of the highlights of the research career of Chuck Newman. This introduction is divided into two main sections, the first covering Chuck’s work in
Agent-Based Strategizing
Strategic management is a system of continual disequilibrium, with firms in a continual struggle for competitive advantage and relative fitness. Models that are dynamic in nature are required if we


Metastate approach to thermodynamic chaos
In realistic disordered systems, such as the Edwards-Anderson (EA) spin glass, no order parameter, such as the Parisi overlap distribution, can be both translation-invariant and non-self-averaging.
We present a combination of heuristic and rigorous arguments indicating that both the pure state structure and the overlap structure of realistic spin glasses should be relatively simple: in a large
Thermodynamic Chaos and the Structure of Short-Range Spin Glasses
This paper presents an approach, recently introduced by the authors and based on the notion of “metastates,” to the chaotic size dependence expected in systems with many competing pure states and
Fluctuation Bounds For Interface Free Energies in Spin Glasses
We consider the free energy difference restricted to a finite volume for certain pairs of incongruent thermodynamic states (if they exist) in the Edwards–Anderson Ising spin glass at nonzero
Nature of the spin glass state.
The nature of the spin glass state is investigated by studying changes to the ground state when a weak perturbation is applied to the bulk of the system and the results for the SK and Viana-Bray models agree with the replica symmetry breaking picture.
Rounding effects of quenched randomness on first-order phase transitions
Frozen-in disorder in an otherwise homogeneous system, is modeled by interaction terms with random coefficients, given by independent random variables with a translation-invariant distribution. For
Gauge symmetries in random magnetic systems
We study random magnetic systems emphasizing the concept of gauge invariance and gauge-invariant disorder (frustration) introduced by Toulouse and Anderson. We formulate our models in a
Scaling theory of Ising spin glasses
A phenomenological renormalisation-group model is proposed for Ising-like spin glasses. The model parameters are a typical interaction strength and a typical energy barrier for block spins. The

We prove the impossibility of recent attempts to decouple the Replica Symmetry Breaking (RSB) picture for finite-dimensional spin glasses from the existence of many thermodynamic (i.e.,

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.
