Sharp interface limits of phase-field models
K. R. Elder, Martin Grant, Nikolas Provatas +1
The use of continuum phase-field models to describe the motion of well-defined interfaces is discussed for a class of phenomena, that includes order/disorder transitions, spinodal…
Conserved Dynamics and Interface Roughening in Spontaneous Imbibition : A Phase Field Model
M. Dube, M. Rost, K. R. Elder +3
The propagation and roughening of a fluid-gas interface through a disordered medium in the case of capillary driven spontaneous imbibition is considered. The system is described by…
An exact solution for 2+1 dimensional critical collapse
David Garfinkle
We find an exact solution in closed form for the critical collapse of a scalar field with cosmological constant in 2+1 dimensions. This solution agrees with the numerical simulatio…
Signature for local Mixmaster dynamics in U(1) symmetric cosmologies
Beverly K. Berger, Vincent Moncrief
Previous studies \cite{berger98a} have provided strong support for a local, oscillatory approach to the singularity in U(1) symmetric, spatially inhomogeneous vacuum cosmologies on…
Numerical evolution of Brill waves
David Garfinkle, G. Comer Duncan
We report a numerical evolution of axisymmetric Brill waves. The numerical algorithm has new features, including (i) a method for keeping the metric regular on the axis and (ii) th…
Generalized entropy and Noether charge
David Garfinkle, Robert Mann
We find an expression for the generalized gravitational entropy of Hawking in terms of Noether charge. As an example, the entropy of the Taub-Bolt spacetime is calculated.
