De Sitter solutions in N=4 matter coupled supergravity
M. de Roo, D. B. Westra, S. Panda
We investigate the scalar potential of gauged N=4 supergravity with matter. The extremum in the SU(1,1)/U(1) scalars is obtained for an arbitrary number of matter multiplets. The c…
Coincident Dp-branes in codimension two
Shesansu Sekhar Pal, Sudhakar Panda
We derive the mass shell condition for N coincident D0 branes in codimension two i.e. in space-time dimension three. Using this we present the action for this system in first order…
Electromagnetic Strings: Complementarity between Time and Temperature
Supriya Kar, Sudhakar Panda
We investigate some of the intricate features in a gravity decoupling limit of a open bosonic string theory, in a constant electromagnetic (EM-) field. We explain the subtle nature…
On the Cosmological Relevance of the Tachyon
Debajyoti Choudhury, Debashis Ghoshal, Dileep P. Jatkar +1
We analyse of the effective action of the tachyon field on a D-brane, of both bosonic as well as superstring theory. We find that the non-standard kinetic term of the tachyon field…
