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…

Quantum geodesics reflecting the internal structure of stars composed of shells
Sojeong Cheong, Wontae Kim
In general relativity, an external observer cannot distinguish distinct internal structures between two spherically symmetric stars that have the same total mass . However, when…

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…
