The ultraviolet cutoff on a quantum field theory can be interpreted as a
condensate of the affine curvature such that while the maximum of the affine
action gives the power-law corrections, its minimum leads to the emergence of
gravity. This mechanism applies also to fundamental strings as their spinless
unstable ground levels can be represented by the scalar affine curvature such
that open strings (D-branes) decay to closed strings and closed strings to
finite minima with emergent gravity. Affine curvature is less sensitive to
massive string levels than the tachyon, and the field-theoretic and stringy
emergent gravities take the same form. It may be that affine condensation
provides an additional link between the string theory and the known physics at
low energies.
According to the article, the ultraviolet cutoff on a quantum field theory can be interpreted as a condensate of the affine curvature. The maximum of the affine action gives power-law corrections, while its minimum leads to the emergence of gravity. This mechanism can also be applied to fundamental strings, with their spinless unstable ground levels represented by the scalar affine curvature. Open strings (D-branes) decay to closed strings and closed strings eventually reach finite minima with emergent gravity.
The use of affine curvature is advantageous compared to the tachyon as it is less sensitive to massive string levels. Both field-theoretic and stringy emergent gravities exhibit the same form. It is possible that the condensation of affine curvature provides a link between string theory and known physics at low energies.
