First order flows for N=2 extremal black holes and duality invariants
Anna Ceresole, Gianguido Dall'Agata, Sergio Ferrara +1
We derive explicitly the superpotential W for the non-BPS branch of N=2 extremal black holes in terms of duality invariants of special geometry. Although this is done for a one-mod…
Casimir densities for a plate in de Sitter spacetime
A. A. Saharian, T. A. Vardanyan
Wightman function, the vacuum expectation values of the field squared and the energy-momentum tensor are investigated for a scalar field with general curvature coupling parameter i…
Spin Hall Drag
S. M. Badalyan, G. Vignale
We predict a new effect in electronic bilayers: the {\it Spin Hall Drag}. The effect consists in the generation of spin accumulation across one layer by an electric current along t…
Maximizing Influence Propagation in Networks with Community Structure
Aram Galstyan, Vahe Musoyan, Paul Cohen
We consider the algorithmic problem of selecting a set of target nodes that cause the biggest activation cascade in a network. In case when the activation process obeys the diminis…
A summation formula over the zeros of a combination of the associated Legendre functions with a physical application
A. A. Saharian
By using the generalized Abel-Plana formula, we derive a summation formula for the series over the zeros of a combination of the associated Legendre functions with respect to the d…
Vacuum polarization by a cosmic string in de Sitter spacetime
E. R. Bezerra de Mello, A. A. Saharian
In this paper we investigate the vacuum polarization effect associated with a quantum massive scalar field in a higher dimensional de Sitter spacetime in the presence of a cosmic s…
