Gravity Waves and Linear Inflation from Axion Monodromy
Wrapped branes in string compactifications introduce a monodromy that extends the field range of individual closed-string axions to beyond the Planck scale. Furthermore, approximate shift symmetries of the system naturally control corrections to the axion potential. This suggests a general mechanism for chaotic inflation driven by monodromy-extended closedstring axions. We systematically analyz...
متن کاملOscillations in the CMB from Axion Monodromy Inflation
We study the CMB observables in axion monodromy inflation. These well-motivated scenarios for inflation in string theory have monomial potentials over super-Planckian field ranges, with superimposed sinusoidal modulations from instanton effects. Such periodic modulations of the potential can drive resonant enhancements of the correlation functions of cosmological perturbations, with characteris...
متن کاملD6-branes and torsion
The D6-brane spectrum of type IIA vacua based on twisted tori T̃ 6 and RR background fluxes is analyzed. In particular, we compute the torsion factors of Hn(T̃ 6,Z) and describe the effect that they have on D6-brane physics. For instance, the fact that H3(T̃ 6,Z) contains ZN subgroups explains why RR tadpole conditions are affected by geometric fluxes. In addition, the presence of torsional (co)ho...
متن کاملHierarchical axion inflation.
We propose a new field theory mechanism for generating an effective trans-Planckian decay constant from sub-Planckian ones. Using the minimal two axions and a hierarchy between two axion decay constants is sufficient for realizing inflation through nonperturbative effects only and with minimal tuning. The inflationary motion is kept entirely within a sub-Planckian domain. We outline possible st...
متن کاملC2/Zn Fractional branes and Monodromy
We construct geometric representatives for the C/Zn fractional branes in terms of branes wrapping certain exceptional cycles of the resolution. In the process we use large radius and conifold-type monodromies, and also check some of the orbifold quantum symmetries. We find the explicit Seiberg-duality which connects our fractional branes to the ones given by the McKay correspondence. We also co...
