Results on the diffusion equation with rough coefficients

Burak Aksoylu, Horst R. Beyer

We study the behaviour of the solutions of the stationary diffusion equation as a function of a possibly rough (-) diffusivity. This includes the boundary behaviour of…

Doping a semiconductor to create an unconventional metal

N. Manyala, J. F. DiTusa, G. Aeppli +1

Landau Fermi liquid theory, with its pivotal assertion that electrons in metals can be simply understood as independent particles with effective masses replacing the free electron…

Fermi-liquid effects in the gapless state of marginally thin superconducting films

G. Catelani, X. S. Wu, P. W. Adams

We present low temperature tunneling density-of-states measurements in Al films in high parallel magnetic fields. The thickness range of the films, t=6-9 nm, was chosen so that the…

On the quasi-hereditary property for staggered sheaves

Pramod N. Achar

Let G be an algebraic group over an algebraically closed field, acting on a variety X with finitely many orbits. "Staggered sheaves" are certain complexes of G-equivariant coherent…

On the ergoregion instability in rotating gravastars

Cecilia B. M. H. Chirenti, Luciano Rezzolla

The ergoregion instability is known to affect very compact objects that rotate very rapidly and do not possess a horizon. We present here a detailed analysis on the relevance of th…

Baric structures on triangulated categories and coherent sheaves

Pramod N. Achar, David Treumann

We introduce the notion of a "baric structure" on a triangulated category, as an abstraction of S. Morel's weight truncation formalism for mixed l-adic sheaves. We study these stru…
