Slow deformation and lower seismic hazard at the new madrid seismic zone

Global Positioning System (GPS) measurements across the New Madrid seismic zone (NMSZ) in the central United States show little, if any, motion. These data are consistent with platewide continuous… Expand

Critical transitions in colliding cascades

- 1 July 2000

We consider here the interaction of direct and inverse cascades in a hierarchical nonlinear system that is continuously loaded by external forces. The load is applied to the largest element and is… Expand

Experimental tests of the gravitational inverse-square law for mass separations from 2 to 105 cm.

- 15 December 1985

We report two experiments which test the inverse-square distance dependence of the Newtonian gravitational force law. One experiment uses a torsion balance consisting of a 60-cm-long copper bar… Expand

Spatial inhomogeneity and thermodynamic chaos.

We present a coherent approach to the competition between thermodynamic states in spatially inhomogeneous systems, such as the Edwards-Anderson spin glass with a fixed coupling realization. This… Expand

Multiple states and thermodynamic limits in short-ranged Ising spin-glass models.

We propose a test to distinguish, both numerically and theoretically, between the two competing pictures of short-ranged Ising spin glasses at low temperature: «chaotic» size dependence. Scaling… Expand

Quantization of dynamical systems with Chern-Simons terms.

- Boyanovsky, Newman, Rovelli
- Physics, Medicine
- Physical review. D, Particles and fields
- 15 February 1992

We propose a novel approach to the quantization of Chern-Simons theories in the Hamiltonian framework that is manifestly gauge invariant and does not require gauge fixing. This approach is based on… Expand

Spin-glass model with dimension-dependent ground state multiplicity.

We introduce a new Ising spin-glass model and use it to study the relation between quenched disorder, frustration, ground state mulitplicity, and dimension. The Hamiltonian is of Edwards-Anderson… Expand

Glassiness and constrained dynamics of a short-range nondisordered spin model

We study the low temperature dynamics of a two-dimensional short-range spin system with uniform ferromagnetic interactions, which displays glassiness at low temperatures despite the absence of… Expand

Monte Carlo study of the random-field Ising model.

Using a cluster-flipping Monte Carlo algorithm combined with a generalization of the histogram reweighting scheme of Ferrenberg and Swendsen, we have studied the equilibrium properties of the thermal… Expand
