Symmetry properties of minimizers of a perturbed Dirichlet energy with a boundary penalization

Giovanni Di Fratta, Antonin Monteil, Valeriy Slastikov

We consider -valued maps on a domain minimizing a perturbation of the Dirichlet energy with vertical penalization in and horizontal penaliz…

Micromagnetics of thin films in the presence of Dzyaloshinskii-Moriya interaction

Elisa Davoli, Giovanni Di Fratta, Dirk Praetorius +1

In this paper, we study the thin-film limit of the micromagnetic energy functional in the presence of bulk Dzyaloshinskii-Moriya interaction (DMI). Our analysis includes both a sta…

Parking 3-sphere swimmer II. The long arm asymptotic regime

François Alouges, Giovanni Di Fratta

The paper carries on our previous investigations on the complementary version of Purcell's rotator: a low-Reynolds-number swimmer composed of three balls of equal radii. In the asy…

Weak-strong uniqueness for the Landau-Lifshitz-Gilbert equation in micromagnetics

Giovanni Di Fratta, Michael Innerberger, Dirk Praetorius

We consider the time-dependent Landau-Lifshitz-Gilbert equation. We prove that each weak solution coincides with the (unique) strong solution, as long as the latter exists in time.…

Variational principles of micromagnetics revisited

Giovanni Di Fratta, Cyrill B. Muratov, Filipp N. Rybakov +1

We revisit the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution…

A short proof of local regularity of distributional solutions of Poisson's equation

Giovanni Di Fratta, Alberto Fiorenza

We prove a local regularity result for distributional solutions of the Poisson's equation with data. We use a very short argument based on Weyl's lemma and Riesz-Fréchet repr…
