Monopoles in String Theory
A realization of En+1 monopoles in string theory is given. The NS five brane stuck to an Orientifold eight plane is identified as the ’t Hooft Polyakov monopole. Correspondingly, the moduli space of many such NS branes is identified with the moduli space of SU(2) monopoles. These monopoles transform in the spinor representation of an SO(2n) gauge group when n D8 branes are stacked upon the orie...
متن کاملMagnetic Monopoles in String Theory
Magnetic monopole solutions to heterotic string theory are discussed in toroidal compactifications to four spacetime dimensions. Particular emphasis is placed on the relation to previously studied fivebrane solutions in ten dimensions and on the possibility of constructing exact monopole solutions related to symmetric fivebranes.
متن کاملM-Theory and String-String Duality
In this article we examine the compatibility of some recent results, results relating M-Theory to String Theory, with the string-string duality conjecture in six-dimensions. In particular, we rederive the relation between M-Theory and Type IIA strings. We then go on to examine in detail M-Theory on K3× S and its relation to the Heterotic theory on T . We conclude with some remarks on M-Theory o...
متن کاملMonopoles and instantons in string theory.
In recent work, several classes of solitonic solutions of string theory with highermembrane structure have been obtained. These solutions can be classified according to the symmetry possessed by the solitons in the subspace of the spacetime transverse to the membrane. Solitons with four-dimensional spherical symmetry represent instanton solutions in string theory, while those with three-dimensi...
متن کاملS-Duality and the Spectrum of Magnetic Monopoles in Heterotic String Theory
We discuss the predictions of S-duality for the monopole spectrum of four-dimensional heterotic string theory resulting from toroidal compactification. We discuss in detail the spectrum of “H-monopoles” , states that are magnetically charged with respect to the U(1) groups arising from the dimensional reduction of the ten dimensional antisymmetric tensor field. Using an assumption concerning th...
