TL;DR: In this paper, the total direct double photoionization rates in the strong-field approximation for a one-dimensional model were calculated and the role of the electron-electron repulsion in the final state for different frequencies and intensities of the applied laser field.

TL;DR: The requirement of an SL(2) duality symmetry, mixing the worldvolume field equations with Bianchi identities, leads to a highly nonlinear equation involving the transformation parameters and certain worldvolume currents as mentioned in this paper.
Abstract: The requirement of an SL(2) duality symmetry, mixing the worldvolume field equations with Bianchi identities, leads to a highly nonlinear equation involving the transformation parameters and certain worldvolume currents In general, this equation seems to admit a solution only for a two parameter subgroup of the seeked SL(2) These transformations also leave invariant the first class constraints generating the worldvolume reparametrizations In the special case of p-branes in p+1 dimensions, the full SL(2) is realized
