Density fluctuations in -deformed inflationary universe

Hyeong-Chan Kim, Jae Hyung Yee, Chaiho Rim

We study the spectrum of metric fluctuation in -deformed inflationary universe. We write the theory of scalar metric fluctuations in the deformed Robertson-Walker space, whi…

Propagation of Light in Doubly Special Relativity

Sung Ku Kim, Sun Myong Kim, Chaiho Rim +1

In an attempt to clarify what is the velocity of a particle in doubly special relativity, we solve Maxwell's equations invariant under the position-space nonlinear Lorentz transfor…

Dimensional Dependence of Black Hole Formation in Self-Similar Collapse of Scalar Field

Hyeong-Chan Kim, Sei-Hoon Moon, Jae Hyung Yee

We study classical and quantum self-similar collapses of a massless scalar field in higher dimensions, and examine how the increase in the number of dimensions affects gravitationa…

Black Hole Decay and Quantum Instantons

Donsu Bak, Sang Pyo Kim, Sung Ku Kim +2

We study the analytic structure of the S-matrix which is obtained from the reduced Wheeler-DeWitt wave function describing spherically symmetric gravitational collapse of massless…

Gravitational Collapse and Calogero Model

Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2

We study the analytic structure of the S-matrix which is obtained from the reduced Wheeler-DeWitt wave function describing spherically symmetric gravitational collapse of massless…

Wave Functions for Quantum Black Hole Formation in Scalar Field Collapse

Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2

We study quantum mechanically the self-similar black hole formation by collapsing scalar field and find the wave functions that give the correct semiclassical limit. In contrast to…
