We explore the possibility that quantum cosmology considerations could provide a selection principle in the landscape of string vacua. We propose that the universe emerged from the string era in a thermally excited state and determine, within a mini-superspace model, the probability of tunneling to different points on the landscape. We find that the potential energy of the tunneling endpoint from which the universe emerges and begins its classical evolution is determined by the primordial… Expand
A Note on the quantum creation of universes
• Physics
• 2006
We elucidate the nature of the correction to the Hartle-Hawking wavefunction presented in hep-th/$0505104$ and hep-th/$0406107$. The correction comes from the quantum fluctuation of the metric thatExpand
Cosmological landscape from nothing: some like it hot
• Physics
• 2006
We suggest a novel picture of the quantum Universe—its creation is described through the density matrix defined by the Euclidean path integral. This yields an ensemble of universes—a cosmologicalExpand
Cosmological landscape and Euclidean quantum gravity
• Physics

Quantum creation of the universe is described by the density matrix defined by the Euclidean path integral. This yields an ensemble of universes—a cosmological landscape—in a mixed quasi-thermalExpand
Cosmological moduli dynamics
• Physics
• 2007
Low energy effective actions arising from string theory typically contain many scalar fields, some with a very complicated potential and others with no potential at all. The evolution of theseExpand
Unitarity at infinity and topological holography
Abstract Recently it has been suggested that non-Gaussian inflationary perturbations can be usefully analysed in terms of a putative dual gauge theory defined on the future conformal infinityExpand
Pre-inflationary spacetime in string cosmology
Abstract Seiberg and Witten have shown that the non-perturbative stability of string physics on conformally compactified spacetimes is related to the behaviour of the areas and volumes of certainExpand
Quantization of parameters and the string landscape problem
• Physics
• 2007
We broaden the domain of application of Brustein and de Alwis's recent paper, where they introduce a (dynamical) selection principle on the landscape of string solutions using FRW quantum cosmology.Expand
A phase space description of the FLRW quantum cosmology in Hořava–Lifshitz type gravity
• Physics

Quantum cosmology of the Friedmann-Robertson-Walker model with cosmological constant in the Ho$\check{\rm r}$ava-Lifshitz type gravity is studied in the phase space by means of the Wigner function.Expand
Instanton transition in thermal and moduli deformed de Sitter cosmology
• Physics
• 2008
Abstract We consider the de Sitter cosmology deformed by the presence of a thermal bath of radiation and/or time-dependent moduli fields. Depending on the parameters, either a first or second-orderExpand
Quantum cosmology from superstrings
• Physics
• 2007
We consider classical superstring theories on flat four dimensional space-times, and where N = 4 or N = 2 supersymmetry is spontaneously broken. We obtain the thermal and quantum corrections at theExpand

The current “standard model” of particle physics—which is nearly 25 years old, has much experimental evidence in its favor and is comprised of six quarks, six leptons, four forces, and the as yet unobserved Higgs boson—contains internal indications that it, too, may be just another step along the path toward uncovering the truly fundamental degrees of freedom.
