We review the boundary state description of D-branes in type I string theory and show that the only stable non-BPS configurations are the D-particle and the D-instanton. We also compute the gauge and gravitational interactions of the non-BPS D-partic

Stable non-BPS D-branes of type I

Gauge and gravitational interactions of non-BPS D-particles

Autor: Gallot, L., Lerda, A., Strigazzi, P.

Publikováno v: Nucl.Phys. B586 (2000) 206-230

We study the gauge and gravitational interactions of the stable non-BPS D-particles of the type I string theory. The gravitational interactions are obtained using the boundary state formalism while the SO(32) gauge interactions are determined by eval

Stable non-BPS D-branes in Type I string theory

Publikováno v: Nucl.Phys.B564:60-85,2000

We use the boundary state formalism to study, from the closed string point of view, superpositions of branes and anti-branes which are relevant in some non-perturbative string dualities. Treating the tachyon instability of these systems as proposed b

A two-dimensional model of Fredericks effect was used for the investigation of the static electric field influence on nematic liquid crystal director orientation in the side-electrode cell. The solutions of the equations describing the model were obt
