Burt Ovrut is an American Theoretical Physicist
most famous for his work on heterotic string theory. He is currently Professor of Theoretical High Energy Physics at the University of Pennsylvania
.
Burt Ovrut earned his Ph.D.
in physics at the University of Chicago
in 1978. His doctoral advisors were Benjamin W. Lee
and Yoichiro Nambu
, and his thesis was on an Sp(4) x U(1) Theory of the Weak and Electromagnetic Interactions.
He is one of those who pioneered the use of M-theory
to explain the Big bang
without the presence of a singularity
. Recently Burt Ovrut and his collaborators constructed a Calabi-Yau compactification that reproduces the Minimal Supersymmetric Standard Model
without any exotics.

Yoichiro Nambu

M-theory
In theoretical physics, M-theory is an extension of string theory in which 11 dimensions are identified. Because the dimensionality exceeds that of superstring theories in 10 dimensions, proponents believe that the 11-dimensional theory unites all five string theories...

Big Bang
The Big Bang theory is the prevailing cosmological model that explains the early development of the Universe. According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly. This rapid expansion caused the young Universe to cool and resulted in...

Gravitational singularity
A gravitational singularity or spacetime singularity is a location where the quantities that are used to measure the gravitational field become infinite in a way that does not depend on the coordinate system...

Minimal Supersymmetric Standard Model
The Minimal Supersymmetric Standard Model is the minimal extension to the Standard Model that realizes supersymmetry, although non-minimal extensions do exist. Supersymmetry pairs bosons with fermions; therefore every Standard Model particle has a partner that has yet to be discovered...
