Bulk phantom fields, increasing warp factors and fermion localisation
Ratna Koley, Sayan Kar
A bulk phantom scalar field (with negative kinetic energy) in a sine--Gordon type potential is used to generate an exact thick brane solution with an increasing warp factor. It is…

Scalar kinks and fermion localisation in warped spacetimes
Ratna Koley, Sayan Kar
Scalar kinks propagating along the bulk in warped spacetimes provide a thick brane realisation of the braneworld. We consider here, a class of such exact solutions of the full Eins…
