Vera C. Rubin: Pioneering American astronomer (1928-2016).

Vera Cooper Rubin, an icon of astronomy whose work revolutionized our understanding of the universe by confirming the existence of dark matter, passed away on December 25, 2016 at the age of 88. Vera had a lifelong love of the cosmos. “How could you possibly live on this Earth and not want to study the universe?” shewondered. Vera was a devoted champion of women in science and a beloved role mo...

Freund-rubin Revisited

We utilise the duality between M theory and Type IIA string theory to show the existence of Freund-Rubin compactifications of M theory on 7-manifolds with singularities supporting chiral fermions. This leads to a concrete way to study phenomenologically interesting quantum gravity vacua using a holographically dual three dimensional field theory. bacharya, denef, hofman, [email protected]...

Verlustmessung in Rubin-Lasern

The amplification of light in a laser ruby depends on the angle between the direction of polarization and the c-axis of the crystal. This leads to a changing threshold if the plane of polarization is rotated within the cavity. The change in threshold can be compared with the change produced by the addition of a definite loss in the laser cavity. The method is simple because the cavity loss (inc...
