Hawking Radiation as Quantum Tunneling in Rindler Coordinate
Sang Pyo Kim
We substantiate the Hawking radiation as quantum tunneling of fields or particles crossing the horizon by using the Rindler coordinate. The thermal spectrum detected by an accelera…
Schwinger Mechanism and Hawking Radiation as Quantum Tunneling
Sang Pyo Kim
The common interpretation of the Hawking radiation as quantum tunneling has some ambiguity such as coordinate-dependence of tunneling rate and non-invariance of the action under ca…
Spacetime structure of 5D hypercylindrical vacuum solutions with tension
Inyong Cho, Gungwon Kang, Sang Pyo Kim +1
We investigate geometrical properties of 5D cylindrical vacuum solutions with a transverse spherical symmetry. The metric is uniform along the fifth direction and characterized by…
Quantum Entanglement and Teleportation in Higher Dimensional Black Hole Spacetimes
Xian-Hui Ge, Sang Pyo Kim
We study the properties of quantum entanglement and teleportation in the background of stationary and rotating curved space-times with extra dimensions. We show that a maximally en…
Schwinger Pair Production at Finite Temperature in Scalar QED
Sang Pyo Kim, Hyun Kyu Lee
In scalar QED we study the Schwinger pair production from an initial ensemble of charged bosons when an electric field is turned on for a finite period together with or without a c…
Ricci Flat Black Holes and Hawking-Page Phase Transition in Gauss-Bonnet Gravity and Dilaton Gravity
Rong-Gen Cai, Sang Pyo Kim, Bin Wang
It is well-known that there exists a Hawking-Page phase transition between a spherical AdS black hole and a thermal AdS space. The phase transition does not happen between a Ricci…
Ellipsoidal universe in the brane world
Xian-Hui Ge, Sang Pyo Kim
We study a scenario of the ellipsoidal universe in the brane world cosmology with a cosmological constant in the bulk . From the five-dimensional Einstein equations we derive the e…
Improved Approximations for Fermion Pair Production in Inhomogeneous Electric Fields
Sang Pyo Kim, Don N. Page
Reformulating the instantons in a complex plane for tunneling or transmitting states, we calculate the pair-production rate of charged fermions in a spatially localized electric fi…
Quantum Fluctuations in the Inflationary Universe
Sang Pyo Kim
The recent three-year WMAP data selects large-field models with certain power-law potentials and small-field models for all power-law potentials as consistent inflation models. We…
