Theoretical Quantum Physics, Gravitation and Cosmology, Kyushu University
(Theoretical Astrophysics Group, Kyushu University)
WELCOME TO THE
Theoretical Quantum Physics, Gravitation and Cosmology Group
Our group is a division of the department of Physics at Kyushu University.
The members investigate a wide range of topics in cosmology, gravity, and relativistic quantum information. The question we seek to answer in cosmology is
"How did our universe begin and how will it end?"
In gravity and relativistic quantum information, we are tackling fundamental challenges about the quantum nature of gravity, including its relationship to quantum field theory of gravity and feasibility of future experiments.
