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…
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…
