Monodromy in the CMB: Gravity Waves and String Inflation
We present a simple mechanism for obtaining large-field inflation, and hence a gravitational wave signature, from string theory compactified on twisted tori. For Nil manifolds, we obtain a leading inflationary potential proportional to φ 2/3 in terms of the canonically normalized field φ, yielding predictions for the tilt of the power spectrum and the tensor-to-scalar ratio, n s ≈ 0.98 and r ≈ ...
متن کاملPunctuated inflation and the low CMB multipoles
We investigate inflationary scenarios driven by a class of potentials which are similar in form to those that arise in certain minimal supersymmetric extensions of the standard model. We find that these potentials allow a brief period of departure from inflation sandwiched between two stages of slow roll inflation. We show that such a background behavior leads to a step like feature in the scal...
متن کامل3 CMB , Quantum Fluctuations and the Predictive Power of Inflation
I comment on the predictive power of inflation and recent CMB measurements. When more than twenty years ago G. Chibisov and I were fortunate to discover that quantum fluctuations could be responsible for the large scale structure of the universe, we hardly thought it would be possible one day to verify this prediction experimentally. We wrote a paper we derived the spectrum of cosmological metr...
متن کاملLow-l CMB analysis and inpainting
Reconstructing the cosmic microwave background (CMB) in the Galactic plane is extremely difficult due to the dominant foreground emissions such as dust, free-free or synchrotron. For cosmological studies, the standard approach consists in masking this area where the reconstruction is insufficient. This leads to difficulties for the statistical analysis of the CMB map, especially at very large s...
متن کاملTesting String Theory with CMB
Future detection/non-detection of tensor modes from inflation in CMB observations presents a unique way to test certain features of string theory. Current limit on the ratio of tensor to scalar perturbations, r = T/S, is r <∼ 0.3, future detection may take place for r >∼ 10−2 − 10−3. At present all known string theory inflation models predict tensor modes well below the level of detection. Ther...
