Annealed estimates on the Green function
Daniel Marahrens,Felix Otto +1 more
TL;DR: In this paper, the authors considered a random, uniformly elliptic coefficient field (a(x)) on the Z-dimensional integer lattice and showed that the spatial correlation of the coefficient field decays sufficiently fast to the effect that a logarithmic Sobolev inequality holds.

TL;DR: In this article, the authors considered a random, uniformly elliptic coefficient field and showed that the spatial correlation of the coefficient field decays sufficiently fast to the effect that a logarithmic Sobolev inequality holds for the ensemble.

On the Cauchy problem for nonlinear Schrodinger equations with rotation
TL;DR: In this paper, the Cauchy problem for nonlinear Schrodinger equations with sub-quadratic external potentials and an additional angular momentum rotation term was considered and global existence was shown for defocusing nonlinearities without any restriction on the rotation frequency.

Optimal bilinear control of Gross-Pitaevskii equations
TL;DR: In this paper, a mathematical framework for optimal bilinear control of nonlinear Schrodinger equations of Gross-Pitaevskii type arising in the description of Bose-Einstein condensates is presented.

Optimal Bilinear Control of Gross--Pitaevskii Equations
TL;DR: A mathematical framework for optimal bilinear control of nonlinear Schrodinger equations of Gross--Pitaevskii type arising in the description of Bose--Einstein condensates is presented and the first order optimality system is rigorously derived.
