Sharp Convergence to the Half-Space for Mullins-Sekerka in the Plane

Wenhui Shi, Maria G. Westdickenberg, Michael Westdickenberg

We revisit the HED Method for the Mullins-Sekerka evolution in the plane. We identify a natural notion of distance, intrinsic to the interface itself. Using this distance, the ener…

Optimal relaxation of bump-like solutions of the one-dimensional Cahn-Hilliard equation

Sarah Biesenbach, Richard Schubert, Maria G. Westdickenberg

REVISED VERSION INCORPORATING THE ERRATUM ON LEMMA 2.1 AND WITH A CORRECTION TO LEMMA 2.8 In this paper we derive optimal relaxation rates for the Cahn-Hilliard equation on the one…

Numerics and analysis of Cahn--Hilliard critical points

Tobias Grafke, Sebastian Scholtes, Alfred Wagner +1

We explore recent progress and open questions concerning local minima and saddle points of the Cahn--Hilliard energy in and the critical parameter regime of large system…

Symmetry of constrained minimizers of the Cahn-Hilliard energy on the torus

Michael Gelantalis, Alfred Wagner, Maria G. Westdickenberg

We establish sufficient conditions for a function on the torus to be equal to its Steiner symmetrization and apply the result to volume-constrained minimizers of the Cahn-Hilliard…

Optimal -type relaxation rates for the Cahn-Hilliard equation on the line

Felix Otto, Sebastian Scholtes, Maria G. Westdickenberg

In this paper we derive optimal algebraic-in-time relaxation rates to the kink for the Cahn-Hilliard equation on the line. We assume that the initial data have a finite distance---…

Optimal relaxation to a planar interface in the Mullins-Sekerka problem

Olga Chugreeva, Felix Otto, Maria G. Westdickenberg

We analyze the convergence rates to a planar interface in the Mullins-Sekerka model by applying a relaxation method based on relationships among distance, energy, and dissipation.…

Metastability of the Cahn-Hilliard equation in one space dimension

Sebastian Scholtes, Maria G. Westdickenberg

We establish metastability of the one-dimensional Cahn-Hilliard equation for initial data that is order-one in energy and order-one in away from a point on the so-ca…

Existence and properties of certain critical points of the Cahn-Hilliard energy

Michael Gelantalis, Alfred Wagner, Maria G. Westdickenberg

The Cahn-Hilliard energy landscape on the torus is explored in the critical regime of large system size and mean value close to . Existence and properties of a "droplet-shaped"…

Energy barrier and -convergence in the -dimensional Cahn-Hilliard equation

Michael Gelantalis, Maria G. Westdickenberg

We study the d-dimensional Cahn-Hilliard equation on the flat torus in a parameter regime in which the system size is large and the mean value is close---but not too close---to -1.…

Invariant measure of the stochastic Allen-Cahn equation: the regime of small noise and large system size

Felix Otto, Hendrik Weber, Maria Westdickenberg

We study the invariant measure of the one-dimensional stochastic Allen-Cahn equation for a small noise strength and a large but finite system. We endow the system with inhomogeneou…
