Stochastic Bubble Completion in de Sitter Space: Power Spectrum, Bispectrum, and Infrared Moment Hierarchies
Hyukjung Kim, Alp Kagan Ozmen, Heeseung Zoe
Stochastic bubble nucleation makes the local completion time of a first-order phase transition a random spatial field. We study its power spectrum and equilateral bispectrum in Min…
Phase Transitions and Gravitational Wave Production at the End of Thermal Inflation
Hyukjung Kim, İlayda Kuzu, Kerem Özsoy +3
We investigate the first-order phase transition that terminates thermal inflation and evaluate the associated stochastic gravitational-wave signals. The transition is first charact…
The curvature perturbation generated by thermal fluctuations during thermal inflation
Jeong-Myeong Bae, Hammam Raihan Mohammad, Ewan D. Stewart +1
During thermal inflation, the temperature determines the number of e-folds of expansion of the universe and so thermal fluctuations are magnified into curvature perturbations. We u…
Stability of the electroweak vacuum with respect to vacuum tunneling to the Komatsu vacuum in the cMSSM
Hyukjung Kim, Ewan D. Stewart, Heeseung Zoe
We investigate the stability of the electroweak vacuum with respect to vacuum tunneling to the Komatsu vacuum, which exists when , in the cMSSM. Employing the…
Modeling Cosmological Perturbations of Thermal Inflation
Jeong-Myeong Bae, Sungwook E. Hong, Heeseung Zoe
We consider a simple system consisting of matter, radiation and vacuum components to model the impact of thermal inflation on the evolution of primordial perturbations. The vacuum…
Trapped Gravitational Waves in Jackiw-Teitelboim Gravity
Jeong-Myeong Bae, Ido Ben-Dayan, Marcelo Schiffer +2
We discuss the possibility that gravitational fluctuations ("gravitational-waves") are trapped in space by gravitational interactions in two dimensional Jackiw-Teitelboim gravity.…
