Artifical atoms in interacting graphene quantum dots
Wolfgang Häusler, Reinhold Egger
We describe the theory of few Coulomb-correlated electrons in a magnetic quantum dot formed in graphene. While the corresponding nonrelativistic (Schrödinger) problem is well under…
Nanoscale capillary wetting studied with dissipative particle dynamic
C. Cupelli, B. Henrich, M. Moseler +1
We demonstrate that Multi-Body Dissipative Particle Dynamics (MDPD) can be used as an efficient computational tool for the investigation of nanoscale capillary impregnation of conf…
Exactly solvable model of reactions on a random catalytic chain
G. Oshanin, O. Benichou, A. Blumen
In this paper we study a catalytically-activated A + A \to 0 reaction taking place on a one-dimensional regular lattice which is brought in contact with a reservoir of A particles.…
Exactly solvable model of A + A \to 0 reactions on a heterogeneous catalytic chain
G. Oshanin, O. Benichou, A. Blumen
We present an exact solution describing equilibrium properties of the catalytically-activated A + A \to 0 reaction taking place on a one-dimensional lattice, where some of the site…
The Seyfert Galaxy NGC 6814 -- a highly variable X-ray source
Michael Koenig, Susanne Friedrich, Ruediger Staubert +1
The Seyfert galaxy NGC 6814 is a highly variable X-ray source despite the fact that it has recently been shown not to be the source of periodic variability. The 1.5 year monitoring…
