Phase-field approximation of sharp-interface energies accounting for lattice symmetry
Sergio Conti, Vito Crismale, Adriana Garroni +1
We present a phase-field approximation of sharp-interface energies defined on partitions, designed for modeling grain boundaries in polycrystals. The independent variable takes val…

Clearing-out of dipoles for minimisers of 2-dimensional discrete energies with topological singularities
Adriana Garroni, Mircea Petrache, Emanuele Spadaro
A key question in the analysis of discrete models for material defects, such as vortices in spin systems and superconductors or isolated dislocations in metals, is whether informat…
