On the survival of strong nuggets in the early Universe
Haoyang Qi, Wen-Li Yuan, Yudong Luo +3
Strong nuggets with a baryon number of could be able to survive from the cosmic separation of the QCD phases, provided the transition from strange quark matter t…
Inflationary relics from an Ultra-Slow-Roll plateau
Albert Escrivà, Jaume Garriga, Shi Pi
We investigate the formation of primordial black holes (PBHs) in inflationary scenarios featuring an ultra-slow-roll (USR) plateau with a sharp transition to slow roll. We focus on…
Primordial black holes and induced gravitational waves from logarithmic non-Gaussianity
Ryoto Inui, Cristian Joana, Hayato Motohashi +3
We investigate the formation of primordial black hole (PBH) based on numerical relativity simulations and peak theory as well as the corresponding scalar induced gravitational wave…
Constant roll and non-Gaussian tail in light of logarithmic duality
Ryoto Inui, Hayato Motohashi, Shi Pi +2
The curvature perturbation in a model of constant-roll (CR) inflation is interpreted in view of the logarithmic duality discovered in Ref. [1] according to the formalism. We c…
