Abstract:We construct an action for NSNS 5-branes which is manifestly covariant under O(d, d). This is done by doubling d of the spacetime coordinates which appear in the worldvolume action. By formulating the DBI part of the action in a manner similar to a "gauged sigma model", only half the doubled coordinates genuinely appear. Our approach allows one to describe the full T-duality orbit of the IIB NS5 brane, the IIA KKM and their exotic relations in one formalism. Furthermore, by using ideas from double field theory, our action can be said to describe various aspects of non-geometric five-branes.

Based on the stringy differential geometry we proposed earlier, we incorporate fermions such as gravitino and dilatino into double field theory in a manifestly covariant manner with regard to O(D, D) T-duality, diffeomorphism, one-form gauge symmetry for B-field and a pair of local Lorentz symmetries. We note that there are two kinds of fermions in double field theory: O(D, D) singlet and non-singlet which may be identified, respectively as the common and the non-common fermionic sectors in type IIA and IIB supergravities. For each kind, we construct corresponding covariant Dirac operators. Further, we derive a simple criterion for an O(D, D) rotation to flip the chirality of the O(D, D) non-singlet chiral fermions, which implies the exchange of type IIA and IIB supergravities.

“…Given our limited knowledge as how to quantize string theory in flux backgrounds [39,40,41,42], one can use the non geometric world-sheet construction as an equivalent 'dual' definition of the latter. Indeed duality between geometric fluxes (H ijk 3-form and T ij k torsion) and non geometric ones (Q i jk and R ijk ) has been proposed and supported by some evidence [43,44,45,46,47,48,49,50,51,52,55,54,55,56,57].…”

Bound-states of D-branes in L–R asymmetric superstring vacua

We discuss bound-states of D-branes in truly L-R asymmetric and thus non-geometric Type II vacuum configurations with extended supersymmetry. We argue for their stability as a result of residual supersymmetry and coupling to R-R potentials surviving in the massless spectrum. We then identify the open string excitations of these L-R asymmetric BPS D-branes. Finally, we briefly comment on possible applications and extensions.
