Robert Brandenberger

from Wikipedia, the free encyclopedia

Robert Hans Brandenberger (* 1954 in Bern ) is an American theoretical physicist and cosmologist.

Brandenberger studied at the ETH Zurich (diploma 1978) and at Harvard University (master’s degree 1979), where he received his doctorate in 1983 with William H. Press with the thesis Topics in Quantum Field Theory and Cosmology . As a post-doctoral student he was at the University of California, Santa Barbara until 1985 and then with Stephen Hawking at Cambridge University until 1987 . In 1986 he became an assistant professor and in 1991 an associate professor at Brown University . In 2004 he became a professor at McGill University , where he holds a Canada Research Chair. He is also a member of the Perimeter Institute .

He deals with cosmology and the early universe, in particular the development of large-scale structures and the first galaxies, using models from particle physics and quantum field theory. With Cumrun Vafa in 1989 he developed a cosmology based on string theory (String Gas Cosmology). To this end, they viewed the early universe as a gas of strings (according to the superstring theory in 10 dimensions), and argued that the most likely number of space-time dimensions is four, since only then are the strings that wrap around this space (winding modes, each with 2 space-time dimensions of their world surfaces) have a chance to come into contact and cancel each other out, which in turn is a prerequisite for the expansion of the spaces (the other dimensions do not expand, but keep radii on the Planck scale). The theory has since been expanded.

2011 the CAP-CRM Prize . From 1988 to 1992 he was a Sloan Research Fellow . In 1988 he received an Outstanding Junior Research Award from the Department of Energy and he was a Killam Fellow.

He is a US citizen.
