摘要:Modular inflation is the restriction to two fields of automorphic inflation, a general group based framework for multifield scalar field theories with curved target spaces, which can be parametrized by the comoving curvature perturbation ℛ and the isocurvature perturbation t...

摘要:Abstract(#br)We investigate the pairwise causality of inflation rates across time and frequencies, inflation cycle synchronization and network structure of causality between five ASEAN countries: Indonesia, Malaysia, The Philippines, Singapore, and Thailand. We draw our empiric...

摘要:Abstract(#br)We propose a class of single-field, slow-roll inflation models in which a typical number of e -folds can be extremely large. The key point is to introduce a very shallow local minimum near the top of the potential in a hilltop inflation model. In particular, a typica...

摘要:Abstract(#br)Pension schemes generally aim to protect the purchasing power of their participants, but cannot completely do this when due to market incompleteness inflation risk cannot be fully hedged. Without a market price for inflation risk the value of a pension contract de...

摘要:... The dynamical evolution in such a random potential from a small-field inflation region towards a viable late-time de Sitter (dS) minimum maps to the dynamics of Dyson Brownian motion describing the relaxation of non-equilibrium eigenvalue spectra in random matrix theory. We...

摘要:We propose a simple modification of the no-scale supergravity Wess-Zumino model of Starobinsky-like inflation to include a Polonyi term in the superpotential. The purpose of this term is to provide an explicit mechanism for supersymmetry breaking at the end of inflation. We show ...

摘要:... Abnormal swim bladder inflation in several finfish species leads to malformations, particularly of the vertebral column. The present study examined the influence of swim bladder inflation on saddleback-like syndrome in hatchery-reared red spotted grouper. The incidence of sad...

摘要:We present effects of intrinsic twist and material orthotropy on extension–twist–inflation coupling in circular tubes about their stress-free state. Simple analytical expressions for coupling stiffnesses corresponding to extension–twist, twist–inflation and extension–inflation...

摘要:We propose supersymmetric Majoron inflation in which the Majoron field Φ responsible for generating right-handed neutrino masses may also be suitable for giving low scale “hilltop” inflation, with a discrete lepton number \( {\mathbb{Z}}_N \) spontaneously broken at the...

摘要:... We illustrate it by providing generalized versions of polynomial chaotic inflation, T- and E-models of α -attractor type, disk merger. We also describe a multi-stage cosmological attractor regime, which we call cascade inflation.
