The energy-carrying velocity and rolling of tachyons of unstable D-branes
Jin Hyun Chung, Won Sik L'Yi
It is shown that the tachyons which originate from unstable D-branes carry energy and momentum at the velocity where is the phase velocity which is greater than $c.…
Time evolution of rolling tachyons for a brane-antibrane pair
Haewon Lee, W. S. l'Yi
A precise form of the time evolution of rolling tachyons corresponding to a brane-antibrane pair is investigated by solving the Hamiltonian equations of motion under the assumption…
Domain walls, stabilities, and the mass hierarchy of the Randall-Sundrum Model
Haewon Lee, W. S. l'Yi
Randall-Sundrum model, which has a scalar field, is used to investigate the domain structure of the extra dimension and to obtain a possible solution of the mass hierarchy problem.…
Correlators of currents corresponding to the massive -form fields in AdS/CFT correspondence
W. S. l'Yi
By solving the equations of motion of massive -form potential in Anti-de-Sitter space and using the correspondence of Maldacena, the generating functional of two-point…
Generating functionals of correlation functions of p-form currents in AdS/CFT correspondence
W. S. l'Yi
The generating functional of correlation functions of the currents corresponding to general massless -form potential is calculated in correspondence of Maldacena. For…
Coordinate-space holographic projection of fields and an application to massive vector fields
W. S. l'Yi
General properties of coordinate-space holographic projections of fields in AdS/CFT correspondence, which respect the Ward identity, are investigated. To show the usefulness of thi…
Gauge Unification and Dynamical Supersymmetry Breaking
Eung Jin Chun, Haewon Lee, Won Sik l'Yi
Under the assumption that all the gauge groups in supersymmetric theories unify at the fundamental scale, the numbers and the mass scales of messenger quarks and leptons, as well a…
Non-hermitian techniques of canonical transformations in quantum mechanics
Haewon Lee, W. S. l'Yi
The quantum mechanical version of the four kinds of classical canonical transformations is investigated by using non-hermitian operator techniques. To help understand the usefulnes…
