Is the spectrum of gravitational waves the “Holy Grail” of inflation?
It is often said that detecting a spectrum of primordial gravitational waves via observing B-mode polarization of the Cosmic Microwave Background is the “Holy Grail” of inflation.

Holographic cosmology solutions of problems with pre-inflationary cosmology
In this paper we describe in detail how to solve the problems of pre-inflationary cosmology within the holographic cosmology model of McFadden and Skenderis [1].

Catch-me-if-you-can: the overshoot problem and the weak/inflation hierarchy
We study the overshoot problem in the context of post-inflationary string cosmology (in particular LVS). LVS cosmology features a long kination epoch as the volume modulus rolls down the exponential slope towards the final minimum, with an energy density

Phenomenological Inflationary Model in Supersymmetric Quantum Cosmology
We consider the effective evolution of a phenomenological model from FLRW supersymmetric quantum cosmology with a scalar field. The scalar field acts as a clock and inflaton.

Confronting mukhanov parametrization of inflationary equation-of-State with ACT-DR6
We provide a simple yet effective semi-analytical approach to confront Mukhanov Parametrization of inflationary equation-of-state, 1+ω=β(N+1)α, with the latest ACT-DR6 data employing Hamilton-Jacobi formulation.

Classicalization of quantum fluctuations at the Planck scale in the Rh = ct universe
The quantum to classical transition of fluctuations in the early universe is still not completely understood. Some headway has been made incorporating the effects of decoherence and the squeezing of states, though the methods and procedures continue to ...

Is a loopy and noncommutative early Universe viable?
We conduct a (pre-)inflationary dynamics study of the chaotic quadratic potential within the framework of a simple noncommutative extension of effective loop quantum cosmology put forward recently.

Dynamical dark energy in 0’B braneworlds
We build a novel realization of dark bubble cosmology in non-supersymmetric string theory. Among the simplest models in ten dimensions, the type 0’B orientifold is the unique option which yields a scale-separated construction.

The cosmological heavy ion collider: Fast thermalization after cosmic inflation
Heavy-ion colliders have revealed the process of “fast thermalization”. This experimental break-through has led to new theoretical tools to study the thermalization process at both weak and strong coupling.
