On self-similar axion-dilaton configurations (1912.00078v3)
Published 29 Nov 2019 in hep-th, gr-qc, hep-ph, math-ph, and math.MP
Abstract: We explore self-similar collapse solutions to the Einstein-axion-dilaton system in arbitrary spacetime dimensions, which are invariant under spacetime dilation combined with internal $SL(2,R)$ transformations. We set up a numerical formalism, and test it in four and five dimensions, discovering several new families of solutions in the three conjugacy classes of $SL(2,R)$.
