Hole dynamics and effective hole-hole interaction in a quantum antiferromagnet [PDF]
Physical Review B, 1991 Etude de la dynamique des trous a l'aide d'un Hamiltonien effectif qui prend en compte la contrainte sur le deplacement des trous dans un antiferromagnetique quantique. On trouve qu'il existe une bande de quasiparticules dont la largeur est de l'ordre de J a la partie inferieure du spectre des trous.

Rotating “black holes” with holes in the horizon [PDF]
Physical Review D, 2006 Kerr-Schild solutions of the Einstein-Maxwell field equations, containing semi-infinite axial singular lines, are investigated. It is shown that axial singularities break up the black hole, forming holes in the horizon. As a result, a tube-like region appears which allows matter to escape from the interior without crossing the horizon.

Dirty Black Holes and Hairy Black Holes [PDF]
Physical Review Letters, 1996 An approach based on considerations of the non-classical energy momentum tensor outside the event horizon of a black hole provides additional physical insight into the nature of discrete quantum hair on black holes and its effect on black hole temperature. Our analysis both extends previous work based on the Euclidean action techniques, and corrects an
