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…
Complete Supersymmetric Quantum Mechanics of Magnetic Monopoles in N=4 SYM Theory
Dongsu Bak, Kimyeong Lee, Piljin Yi
We find the most general low energy dynamics of 1/2 BPS monopoles in the N=4 supersymmetric Yang-Mills theories (SYM) when all six adjoint Higgs expectation values are turned on. W…
Deformed Nahm Equation and a Noncommutative BPS Monopole
Dongsu Bak
A deformed Nahm equation for the BPS equation in the noncommutative N=4 supersymmetric U(2) Yang-Mills theory is obtained. Using this, we constructed explicitly a monopole solution…
Comments on the Moduli Dynamics of 1/4 BPS Dyons
Dongsu Bak, Kimyeong Lee
We rederive the nonrelativistic Lagrangian for the low energy dynamics of 1/4 BPS dyons by considering the time dependent fluctuations around classical 1/4 BPS configurations. The…
Quantum 1/4 BPS Dyons
Dongsu Bak, Kimyeong Lee, Piljin Yi
Classical properties of 1/4 BPS dyons were previously well understood both in field theory context and in string theory context. Its quantum properties, however, have been more dif…
Low Energy Dynamics for 1/4 BPS Dyons
Dongsu Bak, Choonkyu Lee, Kimyeong Lee +1
Classical 1/4 BPS configurations consist of 1/2 BPS dyons which are positioned by competing static forces from electromagnetic and Higgs sectors. These forces do not follow the sim…
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…
Semiclassical Limit and Time in Quantum Cosmology
Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2
We propose a method to recover the time variable and the classical evolution of the Universe from the minisuperspace wave function of the Wheeler-DeWitt equation. Defining a Hamilt…
Replication Error and Time Evolution of a Self-Replicating System
Dongsu Bak
A self-replicating system where the elements belonging to a solution category can replicate themselves by copying their own informations, is considered. The information carried by…
Holographic View of Causality and Locality via Branes in AdS/CFT Correspondence
Dongsu Bak, Soo-Jong Rey
We study dynamical aspects of holographic correspondence between d=5 anti-de Sitter supergravity and super Yang-Mills theory. We probe causality and locality of ambient space…
Cosmic Holography
Dongsu Bak, Soo-Jong Rey
A new version of holographic principle for cosmology is proposed, which dictates that particle entropy within `cosmological apparent horizon' should not exceed gravitational entrop…
Moduli Space Dimensions of Multi-Pronged Strings
Dongsu Bak, Koji Hashimoto, Bum-Hoon Lee +2
The numbers of bosonic and fermionic zero modes of multi-pronged strings are counted in super-Yang-Mills theory and compared with those of the IIB string theory. We ob…
Quantum Creation of Black Hole by Tunneling in Scalar Field Collapse
Dongsu Bak, Sang Pyo kim, Sung Ku Kim +2
Continuously self-similar solution of spherically symmetric gravitational collapse of a scalar field is studied to investigate quantum mechanical black hole formation by tunneling…
