Friedmann equations and emergence of cosmic space
Ee Chang-Young, Daeho Lee
In this paper, we show that Padmanabhan's conjecture for the emergence of cosmic space [arXiv:1206.4916] holds for the flat Friedmann-Robertson-Walker universe in Einstein gravity…
Noncommutative Solitonic Black Hole
Ee Chang-Young, Kyoungtae Kimm, Daeho Lee +1
We investigate solitonic black hole solutions in three dimensional noncommutative spacetime. We do this in gravity with negative cosmological constant coupled to a scalar field. No…
Brans-Dicke Gravity from Entropic Viewpoint
Ee Chang-Young, Kyoungtae Kimm, Daeho Lee
We interpret the Brans-Dicke gravity from entropic viewpoint. We first apply the Verlinde's entropic formalism in the Einstein frame, then perform the conformal transformation whic…
Schwarzschild-de Sitter black hole from entropic viewpoint
Ee Chang-Young, Myungseok Eune, Kyoungtae Kimm +1
In a Schwarzschild-de Sitter space, we consider an equipotential surface which consists of two holographic screens. Adapting the Bousso-Hawking's reference point of vanishing force…
Bound of Noncommutativity Parameter Based on Black Hole Entropy
Wontae Kim, Daeho Lee
We study the bound of the noncommutativity parameter in the noncommutative Schwarzschild black hole which is a solution of the noncommutative ISO(3,1) Poincare gauge group. The sta…
Surface gravity and Hawking temperature from entropic force viewpoint
Ee Chang-Young, Myungseok Eune, Kyoungtae Kimm +1
We consider a freely falling holographic screen for the Schwarzschild and Reissner-Nordström black holes and evaluate the entropic force à la Verlinde. When the screen crosses the…
