Gravitational fields of cosmic membranes
M Mukherjee
Show affiliationsThe gravitational field resulting from static scalar field configurations is investigated by means of coupled Einstein-scalar equations. Imposing plane symmetry, the author obtains a family of exact soliton-like stable solutions representing thick cosmic membranes in a spacetime which is flat at spatial infinity. The physical properties of the cosmic membrane (such as thickness, surface energy density, and interior gravitational field) are derived without detailed knowledge of the scalar field, and it is shown that test particles are repelled by the gravitational field of the membrane. Finally, they discuss an interesting possibility of generating a spacetime foliation due to superposition of soliton-like configurations of the scalar field.
