چکیده
We compute the inflationary perturbation spectra and quantity r+8nT to next-to-next-to-leading log order in quantum gravity with purely virtual particles (which means theory R+R2+C2 fakeon prescription/projection for C2). The are functions of running coupling ? (1/k) satisfy cosmic renormalization-group flow equations, which determine tilts coefficients. tensor fluctuations receive contributions from spin-2 ? ?? at every expansion powers ? 1/115. dependence scalar spectrum on mass m?, other hand, starts ?2 corrections, handled perturbatively ratio m?/m?, where m? is inflaton mass. predictions have theoretical errors ranging ?4?10?8 ?3 10?6. Nontrivial issues concerning projection higher orders addressed.

Planck scale inflationary spectra from quantum gravity
We derive the semiclassical evolution of massless minimally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation. We show that the dynamics of trans-Planckian modes can be cast in the form of an effective modified dispersion relation and that high energy corrections in the power spectrum of the cosmic microwave background radiation...
متن کاملInflationary attractors and perturbation spectra in generally coupled gravity.
A generic outcome of theories with scalar-tensor coupling is the existence of inflationary attractors, either power-law or de Sitter. The fluctuations arising during this phase are Gaussian and their spectrum depends on the wavenumber k according to the power-law k 1/(1−p) , where p is the inflationary power-law exponent. We investigate to which extent these properties depend on the coupling fu...

In this paper, using high order perturbative series expansion method, the critical exponents of the order parameter and susceptibility in transition from ferromagnetic to disordered phases for 1D quantum Ising model in transverse field, with ferromagnetic nearest neighbor and anti-ferromagnetic next to nearest neighbor interactions, are calculated. It is found that for small value of the frustr...
متن کاملHamiltonian cosmological perturbation theory with loop quantum gravity corrections
Cosmological perturbation equations are derived systematically in a canonical scheme based on Ashtekar variables. A comparison with the covariant derivation and various subtleties in the calculation and choice of gauges are pointed out. Nevertheless, the treatment is more systematic when correction terms of canonical quantum gravity are to be included. This is done throughout the paper for one ...
متن کاملInflationary parameters and primordial perturbation spectra ⋆
I discuss how parameters describing inflation in the very early universe may be related to primordial perturbation spectra. Precision observations of anisotropies in the cosmic microwave background (CMB) such as those provided by the WMAP satellite offer an unprecedented window onto the physics of the very early universe. To theorists exploring speculative models of physics at high energies, th...
