Cosmological Inflation: Theory and Observations

In this article we review the theory of cosmological inflation with a particular focus on the beautiful connection it provides between the physics of the very small and observations of the very large. We explain how quantum mechanical fluctuations during the inflationary era become macroscopic density fluctuations which leave distinct imprints in the cosmic microwave background (CMB). We descri...

Cosmological inflation and Q-balls

Cosmological Implications of Supersymmetric Cp Violating Phases

In supersymmetric (SUSY) models there are many new CP violating phases beyond the phase δCKM of the Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix. They arise mainly from the soft SUSY breaking parameters which are in general complex. These phases give large one loop contributions to the electric dipole moments (EDM) of the neutron and electron which exceed the current limits. Hence, SUSY phases...

Cosmological Inflation: A Personal Perspective

We present a brief review of Cosmological Inflation from the personal perspective of the author who almost 30 years ago proposed a way of resolving the problem of Cosmological Horizon by employing certain notions and developments from the field of High Energy Physics. Along with a brief introduction of the Horizon and Flatness problems of standard cosmology, this lecture concentrates on persona...

Cosmological Signature of New Parity-Violating Interactions

Are there any manifestations of parity violation other than those observed in weak interactions? A map of the cosmic microwave background (CMB) temperature and polarization will provide a new signature of P violation. We examine two classes of P-violating interactions that would give rise to such a signature. The first interaction leads to a cosmological birefringence, possibly driven by quinte...
