Andreas Albrecht (physicist)

from Wikipedia, the free encyclopedia

Andreas Johann Albrecht (* 1957 ) is an American theoretical physicist who deals with cosmology .

Life

Albrecht studied at Cornell University (Bachelor 1979) and received his doctorate in 1983 from the University of Pennsylvania under Paul Steinhardt on the theory of the inflationary universe ( A new inflationary cosmology ), the first formulation of which was given a few years earlier by Alan Guth . From 1983 to 1985 he was a post-doc at the University of Texas at Austin , then two years at Los Alamos National Laboratory , from 1987 to 1992 at Fermilab and from 1992 to 1998 at Imperial College London , where he was a lecturer and in 1998 a professor. Since 1998 he has been a professor at the University of California, Davis . In 2014 he became a Fellow of the American Association for the Advancement of Science . In 2016 he was elected a member of the American Academy of Arts and Sciences .

Albrecht is best known for the new inflationary model of the universe developed in 1982 with his doctoral supervisor Steinhardt. Later he also dealt with the consequences of the inflationary model, for example in the reheating phase at the end of inflationary expansion, when the ordinary matter of the Universe came into being.

At the end of the 1980s, together with Neil Turok, he numerically investigated the formation of the large-scale structures of the universe through cosmic strings . In the 1990s he worked a. a. with the emergence of the anisotropies in the cosmic background radiation and the resulting restrictions for cosmological models of structure formation and with dark energy .

In 1998 he and João Magueijo proposed a cosmology with the speed of light changing.
