General Criterion for the existence of Supertube and BIon in Curved Target Space
D. K. Park, S. Tamaryan, H. J. W. Müller-Kirsten
The supertube and BIon spike solutions are examined in a general curved target space. The criteria for the existence of these solutions are explicitly derived. Also the equation wh…
Supersphere
D. K. Park, S. Tamaryan, H. J. W. Müller-Kirsten
The spherical D2-brane solution is obtained without RR external background. The solution is shown to preserve supersymmetries. The configurations obtained depend on the int…
D2-branes with magnetic flux in the presence of RR fields
D. K. Park, S. Tamaryan, H. J. W. Müller--Kirsten
D2-branes are studied in the context of Born-Infeld theory as a source of the 3-form RR gauge potential. Considering the static case with only a radial magnetic field it is shown t…
Randall-Sundrum Scenario at Nonzero Temperature
D. K. Park, Hungsoo Kim, Yan-Gang Miao +1
The effect of temperature is investigated in the Randall-Sundrum brane-world scenario. It is shown that for a spacetime ansatz motivated by similarity with AdS/CFT correspondence s…
Holographic Trace Anomaly and Cocycle of Weyl Group
R. Manvelyan, R. Mkrtchyan, H. J. W. Mueller-Kirsten
The behavior of the divergent part of the bulk AdS/CFT effective action is considered with respect to the special finite diffeomorphism transformations acting on the boundary as a…
Gross-Ooguri Phase Transition at Zero and Finite Temperature: Two Circular Wilson Loop Case
Hungsoo Kim, D. K. Park, S. Tamaryan +1
In the context of correspondence the two Wilson loop correlator is examined at both zero and finite temperatures. On the basis of an entirely analytical approach we have…
