Quantum Informational Dark Energy: Dark energy from forgetting
Jae-Weon Lee, Jungjai Lee, Hyeong-Chan Kim
We suggest that dark energy has a quantum informational origin. Landauer's principle associated with the erasure of quantum information at a cosmic horizon implies the non-zero vac…
Extraordinary vacuum black string solutions
Hyeong-Chan Kim, Jungjai Lee
In addition to the boosted static solution there are two other classes of stationary string-like solutions of the vacuum Einstein equation in (4+1)-dimensions. Each class is charac…
Black string and velocity frame dragging
Jungjai Lee, Hyeong-Chan Kim
We investigate velocity frame dragging with the boosted Schwarzschild black string solution and the boosted Kaluza-Klein bubble solution, in which a translational symmetry along th…
Dark energy, inflation and the cosmic coincidence problem
Jungjai Lee, Hyeong-Chan Kim, Jae-Weon Lee
We show that holographic dark energy could explain why the current dark energy density is so small, if there was an inflation with a sufficient expansion in the early universe. It…
Stationary vacuum hyper-cylindrical solution in 4+1 dimensions
Jungjai Lee, Hyeong-Chan Kim
We find a 4+1 dimensional stationary vacuum hyper-cylindrical solution solution which is spherically symmetric in dimensions and invariant under the translation along the fifth…
Dark energy from vacuum entanglement
Jae-Weon Lee, Jungjai Lee, Hyeong-Chan Kim
We suggest that vacuum entanglement energy associated with the entanglement entropy of the universe is the origin of dark energy. The observed properties of dark energy can be expl…
