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 emptiness formation probability of the open XXZ spin-$\tf{1}{2}$ chain
K. K. Kozlowski
This paper is devoted to the study of the emptiness formation probability $τ\pa{m}$ of the open XXZ chain. We derive a closed form for $τ\pa{m}$ at $Δ=\tf{1}{2}$ when the boundary…
Field theory on --Minkowski space revisited: Noether charges and breaking of Lorentz symmetry
L. Freidel, J. Kowalski-Glikman, S. Nowak
This paper is devoted to detailed investigations of free scalar field theory on -Minkowski space. After reviewing necessary mathematical tools we discuss in depth the Lagrangian…
Correlation functions of the open XXZ chain I
N. Kitanine, K. K. Kozlowski, J. M. Maillet +3
We consider the XXZ spin chain with diagonal boundary conditions in the framework of algebraic Bethe Ansatz. Using the explicit computation of the scalar products of Bethe states a…
The maximal D=4 supergravities
Bernard de Wit, Henning Samtleben, Mario Trigiante
All maximal supergravities in four space-time dimensions are presented. The ungauged Lagrangians can be encoded in an E_7(7)\Sp(56,R)/GL(28) matrix associated with the freedom of p…
New Model of N=8 Superconformal Mechanics
F. Delduc, E. Ivanov
Using an N=4, d=1 superfield approach, we construct an N=8 supersymmetric action of the self-interacting off-shell N=8 multiplet {\bf (1, 8, 7)}. This action is found to be invaria…
