We propose a new class of inflationary solutions to the standard cosmological problems (horizon, flatness, monopole,...), based on a modification of old inflation. These models do not require a potential which satisfies the normal inflationary slow-roll conditions. Our universe arises from a single tunneling event as the inflaton leaves the false vacuum. Subsequent dynamics (arising from either the oscillations of the inflaton field or thermal effects) keep a second field trapped in a false… 
Large Scale Power and Running Spectral Index in New Old Inflation
We have proposed a new class of inflationary scenarios in which the first stage of expansion is driven by ''old'' false vacuum inflation. This ends by nucleation of a bubble, which then further
Old inflation in string theory
We propose a stringy version of the old inflation scenario which does not require any slow-roll inflaton potential and is based on a specific example of string compactification with warped metric.
Elliptic inflation: generating the curvature perturbation without slow-roll
There are many inflationary models in which the inflaton field does not satisfy the slow-roll condition. However, in such models, it is always difficult to generate the curvature perturbation during
A Measure of de Sitter entropy and eternal inflation
We show that in any model of non-eternal inflation satisfying the null energy condition, the area of the de Sitter horizon increases by at least one Planck unit in each inflationary e-folding. This
Multibrane inflation and dynamical flattening of the inflaton potential
We investigate the problem of fine tuning of the potential in the KKLMMT warped flux compactification scenario for brane-antibrane inflation in Type IIB string theory. We argue for the importance of
Low scale inflation and the curvaton mechanism
The primordial curvature perturbation may be due to a `curvaton' field, which dominates (or almost dominates) the energy density before it decays. In the simplest version of the curvaton model the
McGill-04 / 04 Inflation in Realistic D-Brane Models
We find successful models of D-brane/anti-brane inflation within a string context. We work within the GKP-IKLT class of type IIB string vacua for which many moduli are stabilized through fluxes, as
Inflation in realistic D-brane models
We find successful models of D-brane/anti-brane inflation within a string context. We work within the GKP-LT class of type IIB string vacua for which many moduli are stabilized through fluxes, as
Curvature perturbation spectrum from false vacuum inflation
In the inflationary cosmology it occurs frequently that the inflaton field is trapped in a local, transient minimum with non‐zero vacuum energy. The difficulty regarding the curvature perturbation

New mechanism for generating density perturbations from inflation
We propose a new mechanism to generate density perturbations in inflationary models. Spatial fluctuations in the decay rate of the inflaton field to ordinary matter lead to fluctuations in the
Inflationary universe: A possible solution to the horizon and flatness problems
The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that
Density perturbations and black hole formation in hybrid inflation.
TLDR
It is shown that density perturbations in hybrid inflation models of the new type can be very large on the scale corresponding to the phase transition, which could lead to a copious production of black holes in these models.

TLDR
A model where inflation ends in a different way, due to a very rapid rolling (‘waterfall’) of a scalar field σ triggered by another scalar Field φ, which can be realized in a much greater variety of models than the new inflationary Universe scenario.
Inflation induced SUSY breaking and flat vacuum directions
Probing String Theory with Modulated Cosmological Fluctuations
Superstring theory, models with extra dimensions and other SUSY models generically predict that the coupling constants are in fact vacuum expectation values of fields like the dilaton, moduli etc.
INFLATION VERSUS THE COSMOLOGICAL MODULI PROBLEM
We show that in generic supergravity theories the mass of the moduli during inflation is larger (or at least of the same order of magnitude) than the Hubble constant. This fact does not depends on
