Stringy Newton gravity with H-flux

초록

A symmetry principle has been shown to augment unambiguously the Einstein field equations, promoting the whole closed-string massless NS-NS sector to stringy graviton fields. Here we consider its weak field approximation, take a nonrelativistic limit, and derive the stringy augmentation of Newton gravity: del(2)Phi = 4 pi G rho + H . H, del . H = 0, del x H = 4 pi GK. Not only the mass density rho but also the current density K is intrinsic to matter. Sourcing H which is of NS-NS H-flux origin, K is nontrivial if the matter is "stringy." H contributes quadratically to the Newton potential, but otherwise is decoupled from the point particle dynamics, i.e., (x) over dot = -del Phi. We define "stringization" analogous to magnetization and discuss regular as well as monopolelike singular solutions.
