Holography, Dimensional Reduction and the Bekenstein Bound
Dongsu Bak, Ho-Ung Yee
We consider dimensional reduction of the lightlike holography of the covariant entropy bound from D+1 dimensional geometry of M X S to the D dimensional geometry M. With a warping…
Troubles with Spacetime Noncommutative Theories: Tachyons or S-branes?
Dongsu Bak, Seok Kim
We find Lorentzian solutions of spacetime noncommutative gauge theories that are localized exponentially in space and time. Together with time translational invariance of the theor…
Time-dependent Currents of a Single-electron Transistor in Dissipative Environments
Jung Hyun Oh, D. Ahn, S. W. Hwang
Currents of the single-electron transistors driven by time-dependent fields via external dissipative circuits are investigated theoretically. By expressing the external circuit in…
Holography with Timelike Bulk Hypersurfaces
Dongsu Bak
We propose a new version of holographic principle. This proposal extends the holographic principle based on the lightsheet to the one constraining the entropy passing through bulk…
Gauge symmetry enhancement in Hamiltonian formalism
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study the Hamiltonian structure of the gauge symmetry enhancement in the enlarged CP(N) model coupled with U(2) Chern-Simons term, which contains a free parameter governing expl…
Relativistic entanglement of Bell states with general momentum
Young Hoon Moon, Doyeol Ahn, Sung Woo Hwang
In this paper, the Lorentz transformation of the entangled Bell states with momentum, not necessarily orthogonal to the boost direction, and spin, is studied. We extended quantum c…
