Shape of black holes
María E. Gabach Clement
It is well known that celestial bodies tend to be spherical due to gravity and that rotation produces deviations from this sphericity. We discuss what is known and expected about t…
The area-angular momentum inequality for black holes in cosmological spacetimes
Maria Eugenia Gabach Clement, Martin Reiris, Walter Simon
For a stable marginally outer trapped surface (MOTS) in an axially symmetric spacetime with cosmological constant and with matter satisfying the dominant energy condition, w…
On the shape of rotating black-holes
Martin Reiris, Maria Eugenia Gabach Clement
We give a thorough description of the shape of rotating axisymmetric stable black-hole (apparent) horizons applicable in dynamical or stationary regimes. It is found that rotation…
Conformally flat black hole initial data, with one cylindrical end
María E. Gabach Clement
We give a complete analytical proof of existence and uniqueness of extreme-like black hole initial data for Einstein equations, which possess a cilindrical end, analogous to extrem…
A simple spectral condition implying separability for states of bipartite quantum systems
M. E. Gabach Clement, G. A. Raggio
For two qubits and for general bipartite quantum systems, we give a simple spectral condition in terms of the ordered eigenvalues of the density matrix which guarantees that the co…
