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…
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…
Second Hopf map and supersymmetric mechanics with Yang monopole
M. Gonzales, Z. Kuznetsova, A. Nersessian +2
We propose to use the second Hopf map for the reduction (via SU(2) group action) of the eight-dimensional N=8 supersymmetric mechanics to five-dimensional supersymmetric systems sp…
Fermionic Casimir effect in de Sitter spacetime
A. A. Saharian
The Casimir densities are investigated for a massive spinor field in de Sitter spacetime with an arbitrary number of toroidally compactified spatial dimensions. The vacuum expectat…
Fermionic vacuum polarization by a cylindrical boundary in the cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian +1
The vacuum expectation values of the energy--momentum tensor and the fermionic condensate are analyzed for a massive spinor field obeying the MIT bag boundary condition on a cylind…
