AbstractWe present a solution obeying classical equation of motion in the low energy limit of heterotic string theory. The solution represents a rotating mass with electric charge and gravitomagnetic monopole moment. The corresponding conserved charges are discussed, and the separability of Hamilton–Jacobi equation for a test body in the spacetime is also investigated. Some numerical results related to the circular motions on equatorial plane are presented, but there is none that supports the existence of such geodesics.

Hamilton Jacobi Equation

The self-adjoint form of the classical equation of motion of the harmonic oscillator is used to derive a Hamiltonian-like equation and the Schrödinger equation in quantum mechanics. A phase variable ϕ(t) instead of time t is used as an independent variable. It is shown that the Hamilton–Jacobi solution in this case is identical with the solution obtained from the Schrödinger equation without the need to introduce the idea of hidden variables or quantum potential.

Global Anomaly

To a tachyon-free O (16) × O (16) heterotic string theory with anomaly-free properties in the low energy limit, we consider the anomaly of the compactified theory in 8, 6 and 4 dimensions. Furthermore, we investigate the global anomaly of the theory and discuss the compactified manifold which will give a consistent low energy theory.

Ernst Potentials

A new coset matrix for low-energy limit of heterotic string theory reduced to three dimensions is constructed. The pair of matrix Ernst potentials uniquely connected with the coset matrix is derived. The action of the symmetry group on the Ernst potentials is established.
