Manifestly T-dual formulation of AdS space
Machiko Hatsuda, Kiyoshi Kamimura, Warren Siegel
We present a manifestly T-dual formulation of curved spaces such as an AdS space. For group manifolds related by the orthogonal vielbein fields the three form H=dB in the doubled s…
Type II chiral affine Lie algebras and string actions in doubled space
Machiko Hatsuda, Kiyoshi Kamimura, Warren Siegel
We present affine Lie algebras generated by the supercovariant derivatives and the supersymmetry generators for the left and right moving modes in the doubled space. Chirality is m…
Ramond-Ramond gauge fields in superspace with manifest T-duality
Machiko Hatsuda, Kiyoshi Kamimura, Warren Siegel
A superspace with manifest T-duality including Ramond-Ramond gauge fields is presented. The superspace is defined by the double nondegenerate super-Poincare algebras where Ramond-R…
Dynamical sectors for a spinning particle in AdS_3
Carles Batlle, Joaquim Gomis, Kiyoshi Kamimura +1
We consider the dynamics of the motion of a particle of mass M and spin J in AdS_3. The study reveals the presence of different dynamical sectors depending on the relative values o…
Superspace with manifest T-duality from type II superstring
Machiko Hatsuda, Kiyoshi Kamimura, Warren Siegel
A superspace formulation of type II superstring background with manifest T-duality symmetry is presented. This manifestly T-dual formulation is constructed in a space spanned by tw…
Dynamical sectors of a relativistic two particle model
Daniele Dominici, Joaquim Gomis, Kiyoshi Kamimura +1
We reconsider a model of two relativistic particles interacting via a multiplicative potential, as an example of a simple dynamical system with sectors, or branches, with different…
