He was chosen by the International Advisory Committee of the
School of Physics of IPM in a meeting in Tehran on April 13th.
The committee members in Tehran meeting were Farhad Ardalan,
Alexander Belavin, Spenta Wadia, Johnathan Ellis, Werner
Nahm and Ashoke Sen. Cumrun Vafa and Robert H. Brandenberger participated in the
meeting via telephone.
The first prize was awarded to Mohammad
Reza Garousi of Mashhad University in 2006.
The citation of the award which was unanimous is:
IPM-Mansouri String Prize is
Iran is fortunate in having many excellent string
theorists doing first-rate research inside the country. We have
decided to award the Freydoon Mansouri Prize on the basis of one particularly imaginative
paper written during the past few years, which has had strong
international impact. We award the Freydoon Mansouri prize to
Alishahiha, who is the faculty member of School of Physics for his paper: ‘DBI
in the Sky:
Non-Gaussianity from Inflation with A
Speed Limit’. This paper has explored
new mechanisms for generating the spectrum of cosmological density
perturbations in the context of strongly-coupled quantum field
theories, using the AdS/CFT correspondence. The paper also points
out characteristic observational signatures of the model, including
a departure from Gaussianity and a substantial tensor component in
the cosmological background radiation. The paper is a rare example
of a possible bridge between deep theory and astrophysical
This is a striking
example of the excellent research being produced by the new
generation of string theorists in Iran. (Award

The winner of the prize Mohsen Alishahiha obtained his B.S. from Sharif
University and M.S. from Tehran University working on physics
applications of non-commutative geometry. He received his PhD from Sharif University working with Farhad Ardalan on
Sieberg-Witten gauge theories. He held a postdoctoral position at IPM
and then another postdoctoral position at CERN, and later at Amsterdam
He returned to Iran in 2003 and has been with IPM since. He is currently a professor of
theoretical physics at IPM.
The work for which the prize was given was done in
Tehran at IPM in 2004.
IPM – Mansouri Prize was established in 2003 in memory of late
Freydoon Mansouri, Professor of University of Cincinnati in the U.S,
who passed away in April 2003. Freydoon Mansouri was an associate of
IPM and had collaborated with IPM researchers extensively.
In his memory a fellowship was also established for a
graduate student working for his or her Ph.D thesis in string
theory. The first fellowship was awarded in 2005 to Mahdi Torabian of
Sharif University of Technology who worked under the supervision
of Mohammad Mehdi Sheikh-Jabbari of IPM and the second one was
awarded to Alireza Tavanfar of IPM who was working under supervision
of Shahrokh Parvizi of IPM in 2007.
