Electromagnetic Casimir densities induced by a conducting cylindrical shell in the cosmic string spacetime
E. R. Bezerra de Mello, V. B. Bezerra, A. A. Saharian
We investigate the renormalized vacuum expectation values of the field square and the energy-momentum tensor for the electromagnetic field inside and outside of a conducting cylind…
Electrostatic self-interaction in the spacetime of a global monopole with finite core
E. R. Bezerra de Mello, A. A. Saharian
In this paper we calculate the induced electrostatic self-energy and self-force for an electrically charged particle placed at rest in the spacetime of a global monopole admitting…
Multi-center MICZ-Kepler system, supersymmetry and integrability
Sergey Krivonos, Armen Nersessian, Vadim Ohanyan
We propose the general scheme of incorporation of the Dirac monopoles into mechanical systems on the three-dimensional conformal flat space. We found that any system (without monop…
Relationship between quantum mechanics with and without monopoles
Levon Mardoyan, Armen Nersessian, Armen Yeranyan
We show that the inclusion of the monopole field in the three- and five-dimensional spherically symmetric quantum mechanical systems, supplied by the addition of the special centri…
Surface Casimir densities and induced cosmological constant in higher dimensional braneworlds
Aram A. Saharian
We investigate the vacuum expectation value of the surface energy-momentum tensor for a massive scalar field with general curvature coupling parameter obeying the Robin boundary co…
Vacuum polarization by a composite topological defect
E. R. Bezerra de Mello, A. A. Saharian
In this paper we analyze one-loop quantum effects of a scalar field induced by a composite topological defect consisting a cosmic string on a p-dimensional brane and a (m+1)-dimens…
