Journal ArticleDOI
Oscillons after inflation.
TL;DR: 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.
Journal ArticleDOI
HACC: Simulating Sky Surveys on State-of-the-Art Supercomputing Architectures
Salman Habib,Adrian Pope,Hal Finkel,Nicholas Frontiere,Nicholas Frontiere,Katrin Heitmann,David Daniel,Patricia Fasel,Vitali Morozov,George Zagaris,Tom Peterka,Tom Peterka,Venkatram Vishwanath,Venkatram Vishwanath,Zarija Lukić,Saba Sehrish,Wei-keng Liao +16 more
TL;DR: HACC (Hardware/Hybrid Accelerated Cosmology Code), a recently developed and evolving cosmology N-body code framework, designed to run efficiently on diverse computing architectures and to scale to millions of cores and beyond, is reported on.
Journal ArticleDOI
Inflaton fragmentation and oscillon formation in three dimensions
TL;DR: In this paper, the authors numerically explore oscillon solutions to the Klein-Gorden equation in an expanding background and verify the predictions of Amin and Shirokoff for the characteristics of individual oscillons for their model.
Journal ArticleDOI
Gravitational Waves from Oscillon Preheating
Shuang-Yong Zhou,Shuang-Yong Zhou,Edmund J. Copeland,Richard Easther,Hal Finkel,Zong-Gang Mou,Paul M. Saffin +6 more
TL;DR: In this article, an isolated oscillon is shown to be spherically symmetric and does not radiate gravitational waves, and the flux of gravitational radiation generated between oscillons is also small.
Oscillons after Inflation
TL;DR: In this article, it was 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.
