Wavefunction of the Universe on the Landscape
Laura Mersini-Houghton
This talk reviews the proposal for dynamically selecting the most probable wavefunction of the universe propagating on the landscape of string theory, by means of quantum cosmology…
Why did the Universe Start from a Low Entropy State?
R. Holman, L. Mersini-Houghton
In previous work, we showed that the answer to the question posed in the title cannot be found within an equilibrium setting. The inclusion of {\em dynamical} backreaction effects…
Suggestion of Explicit Field Transformations underlying Misaligned Supersymmetry
Paul H. Frampton
In order that nonsupersymmetric quiver gauge theories can satisfy naturalness requirements to all orders of perturbation theory, one expects a global symmetry similar to, but diffe…
Multiparametric Quantum Algebras and the Cosmological Constant
Chethan Krishnan, Edoardo Di Napoli
With a view towards applications for de Sitter, we construct the multi-parametric -deformation of the $so(5,\IC)$ algebra using the Faddeev-Reshetikhin-Takhtadzhyan (FRT) formal…
Why the Universe Started from a Low Entropy State
R. Holman, L. Mersini-Houghton
We show that the inclusion of backreaction of massive long wavelengths imposes dynamical constraints on the allowed phase space of initial conditions for inflation, which results i…
Do We Have Evidence for New Physics in the Sky?
Laura Mersini-Houghton
Predicting signatures of string theory on cosmological observables is not sufficient. Often the observable effects string theory may impact upon the cosmological arena may equally…
Testable and Untestable Aspects of Dark Energy
Paul H. Frampton
It has been suggested that dark energy will lead to a frequency cut-off in an experiment involving a Josephson junction. Here we show that were such a cut-off detected, it would ha…
Conformality Emergent In String Phenomenology
Paul H. Frampton
Use of the AdS/CFT correspondence to arrive at phenomenological gauge field theories is discussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with t…
Noncommutative General Relativity
Xavier Calmet, Archil Kobakhidze
We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommuta…
A glimpse at the flat-spacetime limit of quantum gravity using the Bekenstein argument in reverse
Giovanni Amelino-Camelia, Michele Arzano, Andrea Procaccini
An insightful argument for a linear relation between the entropy and the area of a black hole was given by Bekenstein using only the energy-momentum dispersion relation, the uncert…
Superfield integrals in high dimensions
Michael B. Green, Kasper Peeters, Christian Stahn
We present an efficient, covariant, graph-based method to integrate superfields over fermionic spaces of high dimensionality. We illustrate this method with the computation of the…
Tunneling through the quantum horizon
Michele Arzano
The emergence of quantum-gravity induced corrective terms for the probability of emission of a particle from a black hole in the Parikh-Wilczek tunneling framework is studied. It i…
Minimum Length from First Principles
Xavier Calmet, Michael Graesser, Stephen D. H. Hsu
We show that no device or gedanken experiment is capable of measuring a distance less than the Planck length. By "measuring a distance less than the Planck length" we mean, technic…
Hawking Radiation as Tunneling through the Quantum Horizon
Michele Arzano, A. J. M. Medved, Elias C. Vagenas
Planck-scale corrections to the black-hole radiation spectrum in the Parikh-Wilczek tunneling framework are calculated. The corrective terms arise from modifications in the express…
Can we predict for the Non-SUSY sector of the Landscape ?
Laura Mersini-Houghton
We propose a new selection criteria for predicting the most probable wavefunction of the universe that propagates on the string landscape background, by studying its dynamics from…
An application of neutrix calculus to quantum field theory
Y. Jack Ng, H. van Dam
Neutrices are additive groups of negligible functions that do not contain any constants except 0. Their calculus was developed by van der Corput and Hadamard in connection with asy…
Volume Stabilization via Corrections in Type IIB Theory with Fluxes
Konstantin Bobkov
We consider the Type IIB string theory in the presence of various extra -brane pairs compactified on a warped Calabi-Yau threefold that admits a conifold singularity. We…
