Quantized Kähler Geometry and Quantum Gravity
Jungjai Lee, Hyun Seok Yang
It has been often observed that Kähler geometry is essentially a gauge theory whose field strength is identified with the Kähler form. However it has been pursued neither se…
Dark Energy and Dark Matter in Emergent Gravity
Jungjai Lee, Hyun Seok Yang
Emergent gravity can be applied to a large matrix model by considering the vacuum of a noncommutative (NC) Coulomb branch that satisfies the Heisenberg algebra. Due to the fact…
An Efficient Representation of Euclidean Gravity I
Jungjai Lee, John J. Oh, Hyun Seok Yang
We explore how the topology of spacetime fabric is encoded into the local structure of Riemannian metrics using the gauge theory formulation of Euclidean gravity. In part I, we pro…
String or branelike solutions in four-dimensional Einstein gravity in the presence of cosmological constant
Youngone Lee, Gungwon Kang, Hyeong-Chan Kim +1
We investigate string or branelike solutions for four-dimensional vacuum Einstein equations in the presence of cosmological constant. For the case of negative cosmological constant…
Classification of Hypercylindrical Spacetimes with Momentum Flow
Hyeong-Chan Kim, Gungwon Kang, Jungjai Lee +1
For the five-dimensional spacetimes whose four-dimensional sections are static, spherically symmetric () and flat asymptotically, we study the behavior of Arnowitt-Deser-Mis…
Quantum Gravity from Noncommutative Spacetime
Jungjai Lee, Hyun Seok Yang
We review a novel and authentic way to quantize gravity. This novel approach is based on the fact that Einstein gravity can be formulated in terms of a symplectic geometry rather t…
