Scale-invariant spectrum of Lee-Wick model in de Sitter spacetime
Yun Soo Myung, Taeyoon Moon
We obtain a scale-invariant spectrum from the Lee-Wick model in de Sitter spacetime. This model is a fourth-order scalar theory whose mass parameter is determined by . Th…
Cosmological three-coupled scalar theory for the dS/LCFT correspondence
Yun Soo Myung, Taeyoon Moon
We investigate cosmological perturbations generated during de Sitter inflation in the three-coupled scalar theory. This theory is composed of three coupled scalars ()…
Primordial gravitational waves from conformal gravity
Yun Soo Myung, Taeyoon Moon
We investigate the evolution of cosmological perturbations generated during de Sitter inflation in the conformal gravity. Primordial gravitational waves are composed of vector and…
Cosmological singleton gravity theory and dS/LCFT correspondence
Yun Soo Myung, Taeyoon Moon
We study the evolution of cosmological perturbations generated during de Sitter inflation in the singleton gravity theory. This theory is composed of a dipole ghost pair in additio…
Chaos in Lifshitz Spacetimes
Xiaojian Bai, Junde Chen, Bum-Hoon Lee +1
We investigate the chaotic behavior of a circular test string in the Lifshitz spacetimes considering the critical exponent as an external control parameter. It is demonstrated…
Primordial massive gravitational waves from Einstein-Chern-Simons-Weyl gravity
Yun Soo Myung, Taeyoon Moon
We investigate the evolution of cosmological perturbations during de Sitter inflation in the Einstein-Chern-Simons-Weyl gravity. Primordial massive gravitational waves are composed…
