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.

Feshbach-Einstein Condensates [PDF]
We investigate the phase diagram of a two-species Bose-Hubbard model describing atoms and molecules on a lattice, interacting via a Feshbach resonance. We identify a region where the system exhibits an exotic super-Mott phase and regions with phases characterized by atomic and/or molecular condensates.

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

Einstein y la filosofía del siglo XX
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 ...

Rigidity results for closed vacuum static spaces
In this paper we studied rigidity results for closed vacuum static spaces. By using the maximum principle, we achieved rigidity theorems under some pointwise inequalities and showed that the squared norm of the Ricci curvature tensor was discrete.

Hermitian ∗-Einstein Surfaces [PDF]
We study the problem when a compact Hermitian ∗ {\ast } -Einstein surface M M is Kählerian and show that it is true if M M is additionally assumed to be either Einstein or anti-self-dual.

At the 1927 Solvay conference, Albert Einstein presented a thought experiment intended to demonstrate the incompleteness of the quantum mechanical description of reality. In the following years, the experiment was modified by Einstein, de Broglie, and several other commentators into a simple scenario involving the splitting in half of the wave function

Einstein–Cartan cosmologies [PDF]
Cosmologies based on General Relativity encompassing an anti-symmetric connection (torsion) can display nice desirable features as the absence of the initial singularity and the possibility of inflation in the early stage of the universe. After briefly reviewing the standard approach to the cosmology with torsion, we generalize it to demonstrate that ...

Warped product Einstein metrics on homogeneous spaces and homogeneous Ricci solitons [PDF]
In this paper we consider connections between Ricci solitons and Einstein metrics on homogeneous spaces. We show that a semi-algebraic Ricci soliton admits an Einstein one-dimensional extension if the soliton derivation can be chosen to be normal.
