New non-abelian effects on D branes
Roberto Iengo, Jorge G. Russo
We extend the Myers dielectric effect to configurations with angular momentum. The resulting time-dependent N D0 brane bound states can be interpreted as describing rotating fuzzy…
Gravitational collapse of a macroscopic string by a Newtonian description including the effect of gravitational radiation
Roberto Iengo
We make an attempt to dynamically study, in four space-time dimensions, the classical gravitational collapse of a macroscopic circular fundamental string, by a truncation of the Ei…
About the Matrix model computation of three-graviton scattering
Marco Fabbrichesi, Gabriele Ferretti, Roberto Iengo
It is briefly explained why recent claims about the vanishing of the one-loop effective potential in Matrix theory, thus invalidating the possible agreement with supergravity, do n…
Interaction of D-branes on orbifolds and massless particle emission
Faheem Hussain, Roberto Iengo, Carmen Nunez +1
We discuss various D-brane configurations in 4-dimensional orbifold compactifications of type II superstring theory which are point-like 0-branes from the 4-dimensional space-time…
