In this paper, we investigate various inflation models in the context of the no-boundary proposal. We propose that a good inflation model should satisfy three conditions: observational constraints, plausible initial conditions, and naturalness of the model. For various inflation models, we assign the probability to each initial condition using the no-boundary proposal and define a quantitative standard, typicality, to check whether the model satisfies the observational constraints with probable… 

On the no-boundary proposal for ekpyrotic and cyclic cosmologies

The no-boundary proposal provides a compelling theory for the initial conditions of our universe. We study the implications of such initial conditions for ekpyrotic and cyclic cosmologies. These

Initial Condition of the Inflationary Universe and Its Imprint on the Cosmic Microwave Background

There is an apparent power deficit relative to the Lambda-CDM prediction of the CMB spectrum at large scales, which, though not yet statistically significant, persists from WMAP to Planck data. We

No-boundary wave function for two-field inflation

In this paper, we investigate the no-boundary wave function and the complex-valued instantons for two-field inflation models that have different masses. If there is a relatively massive direction, to

Swampland constraints on no-boundary quantum cosmology

The Hartle-Hawking no-boundary proposal describes the quantum creation of the universe. To have a non-negligible probability to obtain a classical expanding universe, eternal inflation is required,

Probability of boundary conditions in quantum cosmology

One of the main interest in quantum cosmology is to determine boundary conditions for the wave function of the universe which can predict observational data of our universe. For this purpose, we

Swampland, trans-Planckian censorship and fine-tuning problem for inflation: tunnelling wavefunction to the rescue

The trans-Planckian censorship conjecture implies that single-field models of inflation require an extreme fine-tuning of the initial conditions due to the very low-scale of inflation. In this work,

Fuzzy Euclidean wormholes in the inflationary universe

Suppression of long-wavelength CMB spectrum from the no-boundary initial condition

The lack of correlations at the long-wavelength scales of the cosmic microwave background spectrum is a long-standing puzzle and it persists in the latest Planck data. By considering the



No-boundary measure and preference for large e-foldings in multi-field inflation

The no-boundary wavefunction of quantum gravity usually assigns only very small probability to long periods of inflation. This was a reason to doubt about the no-boundary wavefunction to explain the

Inflationary paradigm in trouble after Planck2013

No-boundary measure of the universe.

The no-boundary proposal for homogeneous isotropic closed universes with a cosmological constant and a scalar field with a quadratic potential predicts classical behavior at late times if the scalarField is large enough.

Hartle–Hawking no-boundary proposal in dRGT massive gravity: making inflation exponentially more probable

It is known that the no-boundary proposal in the traditional Einstein gravity does not prefer inflation, that is, the probability of realizing a large number of e-folds is exponentially suppressed.

Multiple Inflationary Stages with Varying Equation of State

We consider a model of inflation consisting a single fluid with a time-dependent equation of state. In this phenomenological picture, two periods of inflation are separated by an intermediate

Why does inflation start at the top of the hill

We show why the universe started in an unstable de Sitter state. The quantum origin of our universe implies one must take a ``top down'' approach to the problem of initial conditions in cosmology, in

Planck 2015. XX. Constraints on inflation

We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP large-angle polarization, constrain the

Prescription for successful new inflation

The conditions on the effective (de Sitter space) scalar potential that are required to obtain a successful new-inflationary-Universe scenario are codified into a general prescription. These

Susskind’s challenge to the Hartle–Hawking no-boundary proposal and possible resolutions

Given the observed cosmic acceleration, Leonard Susskind has presented the following argument against the Hartle–Hawking no-boundary proposal for the quantum state of the universe: it should most

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
