Lectures on Gauged Supergravity and Flux Compactifications
Henning Samtleben
The low-energy effective theories describing string compactifications in the presence of fluxes are so-called gauged supergravities: deformations of the standard abelian supergravi…
The Superconformal Gaugings in Three Dimensions
Eric A. Bergshoeff, Olaf Hohm, Diederik Roest +2
We show how three-dimensional superconformal theories for any number N <= 8 of supersymmetries can be obtained by taking a conformal limit of the corresponding three-dimensional ga…
Gauged Supergravities from Twisted Doubled Tori and Non-Geometric String Backgrounds
Gianguido Dall'Agata, Nikolaos Prezas, Henning Samtleben +1
We propose a universal geometric formulation of gauged supergravity in terms of a twisted doubled torus. We focus on string theory (M-theory) reductions with generalized Scherk-Sch…
On the algebraic Bethe Ansatz approach to the correlation functions of the XXZ spin-1/2 Heisenberg chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We present a review of the method we have elaborated to compute the correlation functions of the XXZ spin-1/2 Heisenberg chain. This method is based on the resolution of the quantu…
