Boundary Obstructions and Lapse Freedom in Static Spherical Hollow Cores
Nelson Bolívar, Gabriel Abellán, Ivaylo Vasilev
We analyze a sharply delimited comparison problem for a static spherical hollow core: an empty, flat cavity surrounded by a positive matter wall. In the unit-lapse, flat-slice radi…
Covariance-Driven Momentum Rectification at Liquid-Vapor Interfaces Near Wetting Transitions
Nelson Bolívar, Gabriel Abellán, Ivaylo Vasilev
Zero-mean forcing can generate directed transport when a medium responds in a spatially structured way and the relevant symmetries are broken. Liquid-vapor interfaces are a useful…
The general relativistic double polytrope for anisotropic matter
G. Abellan, E. Fuenmayor, E. Contreras +1
A general formalism recently proposed to study Newtonian polytropes for anisotropic fluids is here extended to the relativistic regime. Thus, it is assumed that a polytropic equati…
The double polytrope for anisotropic matter: Newtonian Case
G. Abellan, E. Fuenmayor, L. Herrera
A general formalism developed few years ago to model polytropic Newtonian stars with anisotropic pressure is applied to model stars for which, both, radial and tangential pressure…
