We examine the oscillon formation in a recently proposed inflation model of the pure natural inflation, where the inflaton is an axion that couples to a strongly coupled pure Yang-Mills theory. The plateau of the inflaton potential, which is favored by recent observations, drives the fragmentation of the inflaton and can produce spatially localized oscillons. We find that the oscillons are formed for $F\ensuremath{\lesssim}\mathcal{O}(0.1){M}_{\mathrm{pl}}$, with $F$ the effective decay… Expand

Decay of I-ball/oscillon in classical field theory
A bstractI-balls/oscillons are long-lived and spatially localized solutions of real scalar fields. They are produced in various contexts of the early universe in, such as, the inflaton evolution andExpand
A review on radiation of oscillons and oscillatons
Numerical simulations show that a massive real scalar field in a nonlinear theory can form long-lived oscillating localized states. For a self-interacting scalar on a fixed background these objectsExpand
Free Streaming Length of Axion-Like Particle After Oscillon/ I-ball Decays
Axion-like particles (ALPs) are pseudoscalar bosons predicted by string theory. The ALPs have a shallower potential than a quadratic one, which induces the instability and can form the solitonicExpand
Oscillons and dark matter
Oscillons are bound states sustained by self-interactions that appear in rather generic scalar models. They can be extremely long-lived and have a built-in formation mechanism—parametric resonanceExpand
Oscillon collapse to black holes
Using numerical relativity simulations we study the dynamics of pseudo-topological objects called oscillons for a class of models inspired by axion-monodromy. Starting from free field solutionsExpand
Quintessential Axion: Inflation and Dark energy

Oscillon of ultra-light axion-like particle
Ultra-light axion-like particle (ULAP) is one of attractive candidates for cold dark matter. Because the de Broglie wavelength of ULAP with mass $\sim 10^{-22} {\rm eV}$ is $\mathcal{O}({\rm kpc})$,Expand
Primordial Black Holes from Inflaton Fragmentation into Oscillons
We show that fragmentation of the inflaton into long-lived spatially localized oscillon configurations can lead to copious production of black holes. In a single-field inflation model primordialExpand
Properties of oscillons in hilltop potentials: energies, shapes, and lifetimes
Oscillons are spatially localised strong fluctuations of a scalar field. They can e.g. form after inflation when the scalar field potential is shallower than quadratic away from the minimum. AlthoughExpand
Fragileness of exact I -ball/oscillon
I-ball/oscillon is a soliton-like oscillating configuration of a real scalar field which lasts for a long time. I-ball/oscillon is a minimum energy state for a given adiabatic invariant, and itsExpand

Oscillons after inflation.
TLDR
It is shown that in a class of well-motivated single-field models, inflation is followed by self resonance, leading to copious oscillon generation and a lengthy period of oscillon domination, possibly leading to novel gravitational effects in the early Universe. Expand
Inflaton Fragmentation and Oscillon Formation in Three Dimensions
Analytical arguments suggest that a large class of scalar field potentials permit the existence of oscillons -- pseudo-stable, non-topological solitons -- in three spatial dimensions. In this paperExpand
Inflaton fragmentation in E models of cosmological α -attractors
Cosmological $\alpha$-attractors are observationally favored due to the asymptotic flatness of the potential. Since its flatness induces the negative pressure even after inflation, the coherentExpand

TLDR
It is found that oscillons in asymmetric potentials associated with a phase transition can generate a pronounced peak in the spectrum of gravitational waves that largely exceeds the linear preheating spectrum. Expand

Reheating after inflation.
TLDR
It is found that at the first stage of reheating the classical inflation field rapidly decays into particles or into other bosons due to a broad parametric resonance, which implies that the inflation field can be a dark matter candidate. Expand
