Thermodynamics of spacetime: The Einstein equation of state. [PDF]

Physical Review Letters, 1995
The Einstein equation is derived from the form of black hole entropy together with the fundamental relation $\delta Q=TdS$ connecting heat, entropy, and temperature.

Boundary conditions for hyperbolic formulations of the Einstein equations [PDF]

, 2003
In regards to the initial-boundary value problem of the Einstein equations, we argue that the projection of the Einstein equations along the normal to the boundary yields necessary and appropriate boundary conditions for a wide class of equivalent ...

Den obegripliga fysiken

Kulturella Perspektiv, 1994
Natural science can both have a profound influence on and be itself influenced by other aspects of culture, even those which at first seem far removed from the laboratory.

Quasi-Einstein metrics on hypersurface families [PDF]

, 2012
We construct quasi-Einstein metrics on some hypersurface families. The hypersurfaces are circle bundles over the product of Fano, K\"ahler-Einstein manifolds.

Space-borne Bose–Einstein condensation for precision interferometry [PDF]

Nature, 2018
Owing to the low-gravity conditions in space, space-borne laboratories enable experiments with extended free-fall times. Because Bose–Einstein condensates have an extremely low expansion energy, space-borne atom interferometers based on Bose–Einstein ...

Black holes in the four-dimensional Einstein-Lovelock gravity [PDF]

Physical Review D, 2020
A ($3+1$)-dimensional Einstein-Gauss-Bonnet theory of gravity has been recently formulated by Glavan and Lin [D. Glavan and C. Lin, Phys. Rev. Lett.

On homogeneous warped product Einstein metrics [PDF]

, 2014
In this article we study homogeneous warped product Einstein metrics and its connections with homogeneous Ricci solitons. We show that homogeneous $(\lambda,n+m)$-Einstein manifolds (which are the bases of homogeneous warped product Einstein metrics) are

Einstein y la filosofía del siglo XX

Arbor: Ciencia, Pensamiento y Cultura, 2007
Se analizan las influencias filosóficas que ayudaron a Albert Einstein en la construcción de la teoría de la relatividad especial, y cómo sus opiniones filosóficas cambiaron con el tiempo para adecuarlas al contenido de su física, un rasgo que es ...
