Free Thermal Convection Driven by Nonlocal Effects
Jorge Ibsen, Rodrigo Soto, Patricio Cordero
We report and explain a convective phenomenon observed in molecular dynamics simulations that cannot be classified either as a hydrodynamics instability nor as a macroscopically fo…
Stellar Equilibrium in 2+1 Dimensions
Norman Cruz, Jorge Zanelli
The hydrostatic equilibrium of a dimensional perfect fluid star in asymptotically anti-de Sitter space is discussed. The interior geometry matches the exterior black-ho…
Quantization of the Gravitational Constant in Odd-Dimensional Gravity
J. Zanelli
It is pointed out that the action recently proposed by Bañados et al. for gravitation in odd dimensions higher (and lower) than four, provides a natural quantization for the gravit…
Geodesic Structure of the 2 + 1 Black Hole
Norman Cruz, Cristián Martínez, Leda Peña
Null and timelike geodesics around a 2+1 black hole are determined. Complete geodesics of both types exist in the rotating black-hole background, but not in the spinless case. Uppe…
