We present a short review of possible applications of the Wheeler-De Witt equation to cosmological models based on the low-energy string effective action, and characterised by an initial regime of asymptotically flat, low energy, weak coupling evolution. Considering in particular a class of duality-related (but classically disconnected) background solutions, we shall discuss the possibility of quantum transitions between the phases of pre-big bang and post-big bang evolution. We will show that… Expand

Quantum Computing for Inflationary, Dark Energy and Dark Matter Cosmology
Cosmology is in an era of rapid discovery especially in areas related to dark energy, dark matter and inflation. Quantum cosmology treats the cosmology quantum mechanically and is important whenExpand

GRACEFUL EXIT IN QUANTUM STRING COSMOLOGY
Abstract We write an O ( d , d )-covariant Wheeler-De Witt equation in the ( d 2 + 1)-dimensional minisuperspace of low-energy cosmological string backgrounds. We discuss explicit examples ofExpand
SCALE FACTOR DUALITY FOR CLASSICAL AND QUANTUM STRINGS
Abstract Duality under inversion of the cosmological scale factor is discussed both for the classical motion of strings in cosmological backgrounds and for genus zero, low energy effective actions.Expand
Quantum String Theory Effective Action
Abstract We present a covariant background field method for quantum string dynamics. It is based on the effective action Γ for fields corresponding to different string modes. A formalism is developedExpand
Low-energy quantum string cosmology
We introduce a Wheeler–De Witt approach to quantum cosmology based on the low-energy string effective action, with an effective dilaton potential included to account for nonperturbative effects and,Expand
Birth of the Universe as quantum scattering in string cosmology
In a Wheeler-DeWitt approach to quantum string cosmology, the present state of the Universe arises from the scattering and reflection of the wave function representing the initial string vacuum inExpand
Elements of string cosmology
Abstract Aspects of string cosmology for critical and non-critical strings are discussed emphasizing the necessity to account for the dilaton dynamics for a proper incorporation of “large-small”Expand
On the initial regime of pre-big bang cosmology

Quantum cosmology and higher-order Lagrangian theories
In this paper the quantum cosmological consequences of introducing a term cubic in the Ricci curvature scalar R into the Einstein--Hilbert action are investigated. It is argued that this termExpand
Canonical and path integral quantization of string cosmology models
We discuss the quantization of a class of string cosmology models that are characterized by scale factor duality invariance. We compute the amplitudes for the full set of classically allowed andExpand
Time Gauge Fixing and Hilbert Space in Quantum String Cosmology
Recently the low-energy effective string theory has been used by Gasperini and Veneziano to elaborate a very interesting scenario for the early history of the universe (“birth of the universe asExpand
