Santa Barbara, Calif. -
David J. Gross, director of the Kavli Institute
for Theoretical Physics (KITP) and the first incumbent of the Frederick
W. Gluck Chair in
Theoretical Physics at the University of California at Santa Barbara,
has been awarded the 2004 Nobel Prize in Physics for solving in 1973
the last great remaining problem of what has
since come to be called "the Standard Model" of the quantum
mechanical picture of reality.

Cosmological perturbations in chiral models
of inflationary expantion of Universe.
The scalar perturbations in inflationary
models based on a non-linear sigma model, are considered.
Under the slow-roll
conditions
analytical solutions for long-wavelength inhomogeneities in general two-component
chiral models and diagonal
three-component chiral model
of special case are written. For inhomogeneities generated at an inflationary
stage, the law of
motion of the comoving curvature {\cal R} is obtained (without using the slow
roll approximations). A
formal expressions for time
evolution of the power spectrum and its spectral index are obtained, which
are valid after the slow-roll
stage also.
