The proposedmodels constitute consistent inflation for the following reasons: The inflationpotential arises dynamically with stabilized saxions, the axion decay constantcan lie in the sub-Planckian region, and consistency with the Planck data isachieved. The axion landscape consisting of $m$ axion pairs is assumed with theaxions in each pair having opposite charges. A fast roll--slow roll splittingmechanism for the axion potential is proposed which is realized with a specialchoice of the axion basis. In this basis the $2m$ coupled equations split into$2m-1$ equations which enter in the fast roll and there is one unique linearcombination of the $2m$ fields which controls the slow roll and thus the powerspectrum of curvature and tensor perturbations. It is shown that a significantpart of the parameter space exists where inflation is successful, i.e., $N_{\\rmpivot} = {[50, 60]}$, the spectral index $n_s$ of curvature perturbations, andthe ratio $r$ of the power spectrum of tensor perturbations and curvatureperturbations, lie in the experimentally allowed regions given by the Planckexperiment. Further, it is shown that the model allows for a significant regionof the parameter space where the effective axion decay constant can lie in thesub-Planckian domain.

This balance has been studied extensively in the context of gaseswith constant mean density. However, many astrophysical systems are contractingunder the influence of external pressure or gravity, and the balance betweendriving and dissipation in a contracting, magnetized medium has yet to bestudied. In this paper we present three-dimensional (3D) magnetohydrodynamic(MHD) simulations of compression in a turbulent, magnetized medium thatresembles the physical conditions inside molecular clouds. We find that in somecircumstances the combination of compression and magnetic fields leads to arate of turbulent dissipation far less than that observed in non-magnetizedgas, or in non-compressing magnetized gas. As a result, a compressing,magnetized gas reaches an equilibrium velocity dispersion much greater thanwould be expected for either the hydrodynamic or the non-compressing case. Weuse the simulation results to construct an analytic model that gives aneffective equation of state for a coarse-grained parcel of the gas, in the formof an ideal equation of state with a polytropic index that depends on thedissipation and energy transfer rates between the magnetic and turbulentcomponents. We argue that the reduced dissipation rate and larger equilibriumvelocity dispersion produced by compressing, magnetized turbulence hasimportant implications for the driving and maintenance of turbulence inmolecular clouds, and for the rates of chemical and radiative processes thatare sensitive to shocks and dissipation.", "keywords_url": "http://semantics.projectchronos.eu/keywords/filterby?url=http://arxiv.org/abs/1705.09657", "stored": "2018-01-20T06:03:11", "published": "2018-01-20T06:03:11", "type_of": "feed" }, { "in_graph": false, "uuid": 5242350427176960, "title": "Bubble nucleation and growth in slow cosmological phase transitions.

Wereview the case of the generality of this theoretical prediction in the case ofa deformation of SR and find that, at least in the simple model based on theanalysis of photon worldlines which is commonly considered, there are manyscenarios compatible with a relativity principle which do not contain a photontime delay. This will be the situation for any modified dispersion relationwhich reduces to $E=|\\vec{p}|$ for photons, independently of the quantumstructure of spacetime. This fact opens up the possibility of aphenomenologically consistent relativistic generalization of SR with a new massscale many orders of magnitude below the Planck mass.", "keywords_url": "http://semantics.projectchronos.eu/keywords/filterby?url=http://arxiv.org/abs/1702.03669", "stored": "2018-01-20T06:03:11", "published": "2018-01-20T06:03:11", "type_of": "feed" } ], "next": "http://semantics.projectchronos.eu/?bookmark=CkoKFgoJcHVibGlzaGVkEgkIwMubne_l2AISLGoQZX5jaHJvbm9zdHJpcGxlc3IYCxILV2ViUmVzb3VyY2UYgICA6NeilgoMGAAgAQ==" }
