Ground-State properties and collective excitations in a 2D Bose-Einstein condensate with gravity-like interatomic attraction
(Springer New York LLC, 2008)We study the ground-state properties of a Bose-Einstein condensate (BEC) with the short-range repulsion and gravitylike 1/r interatomic attraction in two-dimensions (2D). Using the variational approach, we obtain the ... -
Higher dimensional spherically symmetric gravitational theories
(Bilkent University, 1994)We consider all possible theories in spherically symmetric Riemannian geometry in D-dimensions. We find solutions to such theories, in particular black hole solutions of the low energy limit of the string theory in Ddimensions. -
Some exact solutions of colliding waves, black holes and their thermodynamical properties in Dilaton gravity
(Bilkent University, 1998)We consider all possible theories in spherically symmetric Riemannian geometry in D-dimensions. We find solutions to such theories, in particular black hole solutions of the low energy limit of the string theory in ...
