Exact Greybody Factors for the Brane Scalar Field of Five-dimensional Rotating Black Holes
Young-Hwan Hyun, Yoonbai Kim, Seong Chan Park
We study scalar perturbations of the five-dimensional rotating black holes and find an exact solution giving exact description of the Hawking radiation. Mathematically, the full so…
The Exact Amplitudes of Six Polarization Modes for Gravitational Waves
Young-Hwan Hyun, Yoonbai Kim, Seokcheon Lee
The formalism of the exact six polarization modes of gravitational waves is constructed in terms of both the small metric perturbations and the Newman-Penrose scalars. The obtained…
Conformal Frame dependence on Cosmological Observations in Scalar-Tensor Theories of Gravity
Young-Hwan Hyun, Yoonbai Kim, Seokcheon Lee
Cosmological observations provide more accurate values both for background evolution of the Universe and for the structure formation. These values are given by the so-called dark e…
Abelian Projections of the Mass-deformed ABJM theory and Weakly Curved Dual Geometry
Young-Hwan Hyun, Yoonbai Kim, O-Kab Kwon +1
We construct supersymmetric abelian projections of the mass-deformed ABJM theory. There are well-defined dual background geometries for the …
Angle Dependence of Landau Level Spectrum in Twisted Bilayer Graphene
Min-Young Choi, Young-Hwan Hyun, Yoonbai Kim
In the context of the low energy effective theory, the exact Landau level spectrum of quasiparticles in twisted bilayer graphene with small twist angle is analytically obtained by…
Landau problem for bilayer graphene: Exact results
Young-Hwan Hyun, Yoonbai Kim, Corneliu Sochichiu +1
We consider graphene bilayer in a constant magnetic field of arbitrary orientation (i.e. tilted with respect to the graphene plane). In the low energy approximation to tight bindin…
