Supersymmetric String Solitons
These notes are based on lectures given by C. Callan and J. Harvey at the 1991 Trieste Spring School on String Theory and Quantum Gravity. The subject is the construction of supersymmetric soliton solutions to superstring theory. A brief review of solitons and instantons in supersymmetric theories is presented. Yang-Mills instantons are then used to construct soliton solutions to heterotic stri...
متن کاملNonsupersymmetric String Solitons
We begin a search for nonsupersymmetric/supersymmetric dual string pairs by constructing candidate critical nonsupersymmetric strings as solitons in supersymmetric string theories. Using orbifold techniques, one can construct cosmic string solutions which lie in supersymmetric vacua but which do not fall in supermultiplets. We discuss two threedimensional examples in detail. The effective world...
متن کاملRemarks on string solitons
We consider generalized self-duality equations for U(2r) Yang-Mills theory on R8 with quaternionic structure. We employ the extended ADHMmethod in eight dimensions to construct exact soliton solutions of the low-energy effective theory of the heterotic string.

متن کاملThe String Equation and Solitons
Introduction. We are going to present here some brief survey of the results of Theory of Solitons (see [1–3]) from the viewpoint of periodic theory including some new results in the theory of 2-dimensional periodic Schrodinger Operators. A remarkable connection of some very special but highly nontrivial nonlinear (especially one-dimensional) systems with spectral properties of one-dimensional l...
