The reflection component in NS LMXBs

Reflection patterns in the context of object and component technology

coupling relies on polymorphism and dynamic binding. The abstract class or interface must declare all the relevant methods of B. Now suppose an alternative way of coupling A and B which requires a semantic convention defined separately, that is, not as part of the signature of the abstract class or interface: B is replaced by the most general class Object so that no particular signature is defi...

Shot Noise of Mesoscopic Ns Structures : the Role of Andreev Reflection

Hybrid Superstrings in NS-NS Plane Waves

By using the hybrid formalism, superstrings in four-dimensional NS-NS plane waves are studied in a manifest supersymmetric manner. This description of the superstring is obtained by a field redefinition of the RNS worldsheet fields and defined as a topological N = 4 string theory. The Hilbert space consists of two types of representations describing short and long strings. We study the physical...

Dilatonic Parallelizable NS-NS Backgrounds

We complete the classification of parallelizable NS-NS backgrounds in type II super-gravity by adding the dilatonic case to the result of Figueroa-O'Farrill on the non-dilatonic case. We also study the supersymmetry of these parallelizable backgrounds. It is shown that all the dilatonic parallelizable backgrounds have sixteen supersymmetries. The parallelizable pp-wave backgrounds have been rec...

NS-NS fluxes in Hitchin’s generalized geometry

The standard notion of NS-NS 3-form flux is lifted to Hitchin’s generalized geometry. This generalized flux is given in terms of an integral of a modified Nijenhuis operator over a generalized 3-cycle. Explicitly evaluating the generalized flux in a number of familiar examples, we show that it can compute three-form flux, geometric flux and non-geometric Q-flux. Finally, a generalized connectio...
