Induced Cosmological Anisotropies and CMB Anomalies by a non-Abelian Gauge-Gravity Interaction
Bum-Hoon Lee, Hocheol Lee, Wonwoo Lee +2
We present a non-abelian cousin of the model presented in \cite{Lee:2022rtz} which induces cosmological anisotropies on top of standard FLRW geometry. This is in some sense doing a…
Late-time Cosmology without Dark Sector but with Closed String Massless Sector
Hocheol Lee, Jeong-Hyuck Park, Liliana Velasco-Sevilla +1
We explore the possibility of solving the dark energy and the coincidence problems by postulating the massless sector of closed strings. This sector constitutes the gravitational m…
WIMPs in Dilatonic Einstein Gauss-Bonnet Cosmology
Anirban Biswas, Arpan Kar, Bum-Hoon Lee +5
We use the Weakly Interacting Massive Particle (WIMP) thermal decoupling scenario to probe Cosmologies in dilatonic Einstein Gauss-Bonnet (dEGB) gravity, where the Gauss-Bonnet ter…
Homoclinic orbit and the violation of the chaos bound around a black hole with anisotropic matter fields
Soyeon Jeong, Bum-Hoon Lee, Hocheol Lee +1
We study the homoclinic orbit and the violation of chaos bound, which are obtained by particle motions around a black hole that coexist with anisotropic matter fields. The homoclin…
