2d orbifolds with exotic supersymmetry
Ioannis Florakis, Iñaki García-Etxebarria, Dieter Lust +1
We analyse various two dimensional theories arising from compactification of type II and heterotic string theory on asymmetric orbifolds. We find extra supersymmetry generators ari…
Supertranslations and Holography near the Horizon of Schwarzschild Black Holes
Dieter Lust
In this paper we review and discuss several aspects of supertranslations and their associated algebras at the horizon of a Schwarzschild black hole. We will compare two different a…
Locally non-geometric fluxes and missing momenta in M-theory
Dieter Lust, Emanuel Malek, Marc Syvari
We use exceptional field theory to describe locally non-geometric spaces of M-theory of more than three dimensions. For these spaces, we find a new set of locally non-geometric flu…
Scalar Fields, Hierarchical UV/IR Mixing and The Weak Gravity Conjecture
Dieter Lust, Eran Palti
The Weak Gravity Conjecture (WGC) bounds the mass of a particle by its charge. It is expected that this bound can not be below the ultraviolet cut-off scale of the effective theory…
Unwinding strings in semi-flatland
Dieter Lust, Erik Plauschinn, Valentí Vall Camell
We study the dynamics of strings with non-zero winding number around T-duality defects. We deduce that the physics near the core of such non-geometric objects involves winding mode…
Non-linear Realizations and Higher Curvature Supergravity
F. Farakos, S. Ferrara, A. Kehagias +1
We focus on non-linear realizations of local supersymmetry as obtained by using constrained superfields in supergravity. New constraints, beyond those of rigid supersymmetry, are o…
