A Comprehensive Survey on Nanophotonics Neural Networks
Konstantinos Demertzis, Georgios Papadopoulos, Lazaros Iliadis +1
In the last years, materializations of neuromorphic circuits based on nanophotonic arrangements have been proposed, which contain complete optical circuits, laser, photodetectors,…
On Kerr black hole deformations admitting a Carter constant and an invariant criterion for the separability of the wave equation
Georgios O. Papadopoulos, Kostas D. Kokkotas
In a previous work of ours, the most general family of Kerr deformations -- admitting a Carter constant -- has been presented. This time a simple, necessary and sufficient conditio…
Eigenvalue estimates for multi-form modified Dirac operators
J. Gutowski, G. Papadopoulos
We give estimates for the eigenvalues of multi-form modified Dirac operators which are constructed from a standard Dirac operator with the addition of a Clifford algebra element as…
Classification, geometry and applications of supersymmetric backgrounds
U. Gran, J. Gutowski, G. Papadopoulos
We review the remarkable progress that has been made the last 15 years towards the classification of supersymmetric solutions with emphasis on the description of the bilinears and…
Preserving Kerr symmetries in deformed spacetimes
Georgios O. Papadopoulos, Kostas D. Kokkotas
We present a novel approach in constructing deviations of the Kerr spacetime whereas the symmetries can be preserved. The method was applied trivially in all known classical black-…
All superalgebras for warped AdS and black hole near horizon geometries
U. Gran, J. Gutowski, G. Papadopoulos
We identify all symmetry superalgebras of near horizon geometries of black holes with a Killing horizon, assuming the solution is smooth and that the spatial cross s…
