Emergence of Complex Spatio-Temporal Behavior in Nonlinear Field Theories
Marcelo Gleiser, Rafael C. Howell
We investigate the emergence of time-dependent nonperturbative configurations during the evolution of nonlinear scalar field models with symmetric and asymmetric double-well potent…
Correlated and uncorrelated nanoscale heterogeneities in L1_0 solid solutions and their signatures from local and extended probes
Rafael C. Howell, Steven D. Conradson, Angel J. Garcia-Adeva
The phase coexistence of chemically ordered L1_0 and chemically disordered structures within binary alloys is investigated, using the NiMn system as an example. Theoretical and num…
Pair distribution function and structure factor of spherical particles
Rafael C. Howell, Thomas Proffen, Steven D. Conradson
The availability of neutron spallation-source instruments that provide total scattering powder diffraction has led to an increased application of real-space structure analysis usin…
Resonant Nucleation
Marcelo Gleiser, Rafael Howell
We investigate the role played by fast quenching on the decay of metastable (or false vacuum) states. Instead of the exponentially-slow decay rate per unit volume, $Γ_{\rm HN} \sim…
Resonant nucleation of spatio-temporal order via parametric modal amplification
Marcelo Gleiser, Rafael C. Howell
We investigate, analytically and numerically, the emergence of spatio-temporal order in nonequilibrium scalar field theories. The onset of order is triggered by destabilizing inter…
Resonant emergence of global and local spatiotemporal order in a nonlinear field model
Marcelo Gleiser, Rafael C. Howell
We investigate the nonequilibrium evolution of a scalar field in (2+1) dimensions. The field is set in a double-well potential in contact (open) or not (closed) with a heat bath. F…
Emergence of local and global spatio-temporal order on the way to equipartition: A nonlinear field model
Marcelo Gleiser, Rafael C. Howell
This paper has been withdrawn. A much-improved version can be found at hep-ph/0209176.
Nonequilibrium Precursor Model for the Onset of Percolation in a Two-Phase System
Marcelo Gleiser, Rafael Howell, Rudnei O. Ramos
Using a Boltzmann equation, we investigate the nonequilibrium dynamics of nonperturbative fluctuations within the context of Ginzburg-Landau models. As an illustration, we examine…
