Revisiting oscillon formation in KKLT scenario
Shinta Kasuya, Masahiro Kawasaki, Francis Otani +1
KKLT scenario has succeeded in stabilizing the volume modulus and constructing metastable de Sitter (dS) vacua in type IIB string theory. We revisit to investigate the possibility…
Oscillon of Ultra-Light Axion-like Particle
Masahiro Kawasaki, Wakutaka Nakano, Eisuke Sonomoto
Ultra-light axion-like particle (ULAP) is one of attractive candidates for cold dark matter. Because the de Broglie wavelength of ULAP with mass is $\mathc…
Fragileness of Exact I-ball/Oscillon
Masahiro Ibe, Masahiro Kawasaki, Wakutaka Nakano +1
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 inva…
Decay of I-ball/Oscillon in Classical Field Theory
Masahiro Ibe, Masahiro Kawasaki, Wakutaka Nakano +1
I-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 evol…
