Dirichlet-Branes and Ramond-Ramond Charges [PDF]

, 1995
We show that Dirichlet-branes, extended objects defined by mixed Dirichlet-Neumann boundary conditions in string theory, break half of the supersymmetries of the type~II superstring and carry a complete set of electric and magnetic Ramond-Ramond charges.

The complex Liouville string: Worldsheet boundaries and non-perturbative effects

SciPost Physics
We investigate general observables of the complex Liouville string with worldsheet boundaries. We develop a universal formalism that reduces such observables to ordinary closed string amplitudes without boundaries, applicable to any worldsheet string ...

O(D, D) gauge fields in the T-dual string Lagrangian

Journal of High Energy Physics, 2019
We present the string Lagrangian with manifest T-duality. Not only zero-modes but also all string modes are doubled. The gravitational field is an O(D, D) gauge field.

Heterotic-Type II String Duality and the H-Monopole Problem [PDF]

, 1995
Since T-duality has been proved only perturbatively and most of the heterotic states map into solitonic, non-perturbative, type II states, the 6-dimensional string-string duality between the heterotic string and the type II string is not sufficient to ...

String duality and modular forms [PDF]

Physics Letters B, 1997
Tests of duality between heterotic strings on $K3\times T^2$ (restricted on certain Narain moduli subspaces) and type IIA strings on K3-fibered Calabi-Yau threefolds are attempted in the weak coupling regime on the heterotic side by identifying pertinent modular forms related to the computations of string threshold corrections. Concretely we discuss in

T-duality in arbitrary string backgrounds [PDF]

Nuclear Physics B, 1996
T-Duality is a poorly understood symmetry of the space-time fields of string theory that interchanges long and short distances. It is best understood in the context of toroidal compactification where, loosely speaking, radii of the torus are inverted.
