Feller Generators with measurable lower order terms

Franziska Kühn, Markus Kunze

We study perturbations of Feller generators under `lower order terms' with measurable coefficients. We investigate which properties of the original semigroup -- such as positivity,…

Interior Schauder estimates for elliptic equations associated with Lévy operators

Franziska Kühn

We study the local regularity of solutions $f$ to the integro-differential equation $A f = g in U$ associated with the infinitesimal generator $A$ of a Lévy process…

Schauder estimates for equations associated with Lévy generators

Franziska Kühn

We study the regularity of solutions to the integro-differential equation $A f - λ f = g$ associated with the infinitesimal generator $A$ of a Lévy process. We show that gradient estimat…

Critical Spin Liquid versus Valence Bond Glass in Triangular Lattice Organic $κ$ -(ET) $_{2}$ Cu $_{2}$ (CN) $_{3}$

Kira Riedl, Roser Valenti, Stephen M. Winter

In the quest for materials with unconventional quantum phases, the organic triangular-lattice antiferromagnet $κ$ -(ET) $_{2}$ Cu $_{2}$ (CN) $_{3}$ has been extensively discussed as a quantum…
