Yangians in string theory and Yang-Mills theory
Autor: Chiara R. Nappi
Publikováno v: Fortschritte der Physik. 55:604-609
In recent years, higher loop integrability has been the object of much attention. An important part of that discourse is to check that the Yangian symmetry survives at higher loops. We offer a brief update of the progress in this area.

THE RAMOND–RAMOND SELF-DUAL FIVE-FORM'S PARTITION FUNCTION ON T10
Autor: Chiara R. Nappi, Louise Dolan
Publikováno v: Modern Physics Letters A. 15:1261-1273
In view of the recent interest in formulating a quantum theory of Ramond–Ramond p-forms, we exhibit an [Formula: see text] invariant partition function for the chiral four-form of Type IIB string theory on the ten-torus. We follow the strategy used

THERMODYNAMICS OF TWO-DIMENSIONAL BLACK HOLES
Autor: Andrea Pasquinucci, Chiara R. Nappi
Publikováno v: Modern Physics Letters A. :3337-3346
We explore the thermodynamics of a general class of two dimensional dilatonic black-holes. A simple prescription is given that allows us to compute the mass, entropy and thermodynamic potentials, with results in agreement with those obtained by other

A closed, expanding universe in string theory
Autor: Chiara R. Nappi, Edward Witten
Publikováno v: Physics Letters B. 293:309-314
We present a conformal field theory -- obtained from a gauged WZW model -- that describes a closed, inhomogeneous expanding and recollapsing universe in $3+1$ dimensions. A possible violation of cosmic censorship is avoided because the universe recol

Charged black holes in two-dimensional string theory
Autor: Scott A. Yost, Michael McGuigan, Chiara R. Nappi
Publikováno v: Nuclear Physics B. 375:421-450
We discuss two dimensional string theories containing gauge fields introduced either via coupling to open strings, in which case we get a Born-Infeld type action, or via heterotic compactification. The solutions to the modified background field equat

Spin-1 effective actions from open strings
Autor: Chiara R. Nappi, Philip C. Argyres
Publikováno v: Nuclear Physics B. 330:151-173
Interacting equations of motion for spin-1 fields (both neutral and charged) in an electromagnetic background are derived from the open bosonic string by requiring BRST invariance. These equations are linear in the propagating field and exact in the
