Higher-dimensional view on quantum cosmology

چکیده
We argue that the choice of boundary condition for wave function in quantum cosmology depends on UV completion general relativity. provide an explicit example using a braneworld scenario which de Sitter is induced surface Coleman-de Luccia bubble 5-dimensional AdS space. The corresponding conditions are unambiguously fixed by demanding consistency with known physics nucleation and this selects Vilenkin weighting amplitude from 4D viewpoint.

Higher-derivative Quantum Cosmology
The quantum cosmology of a higher-derivative gravity theory arising from the heterotic string effective action is reviewed. A new type of Wheeler-DeWitt equation is obtained when the dilaton is coupled to the quadratic curvature terms. Techniques for solving the Wheeler-DeWitt equation with appropriate boundary conditions shall be described, and implications for semiclassical theories of inflat...
متن کاملTwo-Dimensional Quantum Cosmology*
Two-dimensional quantum gravity coupled to conformally invariant matter with central charge c > 25 has been proposed as a toy model for quantum gravity in higher dimensions. The associated “Wheeler-Dewitt equation” is non-linear and unstable to forming a condensate of baby universes. This will occur even in the classical c + co limit. Small fluctuations about this background describe the propag...
متن کاملHigher-Dimensional Quantum Cryptography
We report on a high-speed quantum cryptography system that utilizes simultaneous entanglement in polarization and in “time-bins”. With multiple degrees of freedom contributing to the secret key, we can achieve over ten bits of random entropy per detected coincidence. In addition, we collect from multiple spots o the downconversion cone to further amplify the data rate to achieve over 10 Mbits o...
متن کاملOn the Initial Singularity Problem in Two-dimensional Quantum Cosmology
The problem of how to put interactions in two-dimensional quantum gravity in the strong coupling regime is studied. It shows that the most general interaction consistent with this symmetry is a Liouville term that contain two parameters (α, β) satisfying the algebraic relation 2β − α = 2 in order to assure the closure of the diffeomorphism algebra. The model is classically soluble and it contai...
متن کاملQuantum Cosmology on the Worldsheet*
Two-dimensional quantum gravity coupled to conformally invariant matter with central charge c > 25 provides a toy model for quantum gravity in four dimensions. Two-dimensional quantum cosmology can thus be studied in terms of string theory in background fields. The large scale cosmological constant depends on non-linear dynamics in the string theory target space and does not appear to be suppre...
