Evolution of the Universe through the Planck epoch

Sivaram, C (Springer, 1986-08)

The problem of the Universe emerging out of the Planck epoch is discussed. It is pointed out that an earlier exponential expansion phase well before the onset of the GUTs phase transition is essential. Such an expansion ...
Fundamental interactions in the early universe

Sivaram, C (Springer, 1994-05)

A unified approach to fundamental interactions as explored earlier is further elaborated and its consequences for the early universe studied especially in connection with the energy dependence of the coupling constants.
Planetary heat flow limits on monopole and axion fluxes

Sivaram, C (D. Reidel Publishing Co., 1987-02)

Recent improvements in the quantitative estimates of the observed heat flow from planetary objects of the solar system may be used to put rather stringent limits on any background monopole flux. The axion flux from the ...
