Natural inflation in supergravity and beyond

, 2014
Supergravity models of natural inflation and its generalizations are presented. These models are special examples of the class of supergravity models proposed in arXiv:1008.3375 and arXiv:1011.5945, which have a shift symmetric K\"ahler potential ...

Non-relativistic Chern-Simons supergravity with torsion

Journal of High Energy Physics
In this work, we construct a three-dimensional non-relativistic Chern-Simons supergravity theory with both curvature and torsion within the Mielke-Baekler framework.

Minimal Supergravity Models of Inflation

, 2013
We present a superconformal master action for a class of supergravity models with one arbitrary function defining the Jordan frame. It leads to a gauge-invariant action for a real vector multiplet, which upon gauge fixing describes a massive vector ...

HKT geometry and fake five-dimensional supergravity [PDF]

, 2010
Recent results on the relation between hyper-Kahler geometry with torsion and solutions admitting Killing spinors in minimal de Sitter supergravity are extended to more general supergravity models with vector ...

Flux quantization on 11-dimensional superspace

Journal of High Energy Physics
Flux quantization of the C-field in 11d supergravity is arguably necessary for the (UV-)completion of the theory, in that it determines the torsion charges carried by small numbers N ≪ ∞ of M-branes.

Gauge supergravity in D = 2 + 2

Journal of High Energy Physics, 2017
We present an action for chiral N = (1, 0) supergravity in 2 + 2 dimensions. The fields of the theory are organized into an OSp(1|4) connection supermatrix, and are given by the usual vierbein V a , spin connection ω ab , and Majorana gravitino ψ.

KK Compactification of Supergravity Models

, 2019
In this chapter, we will study the KK compactification of supergravity models in higher dimensions. Supergravity models in higher dimensions have: -a graviton, described by the metric gμν (which can be written as eμaηabeνb ), except for the coupling to ...

The clockwork supergravity

Journal of High Energy Physics, 2018
We show that the minimal D = 5, N $$ \mathcal{N} $$ = 2 gauged supergravity set-up may encode naturally the recently proposed clockwork mechanism. The minimal embedding requires one vector multiplet in addition to the supergravity multiplet and the ...

Strings, branes, and gravity duals of gauge theories [PDF]

, 2002
We study the correspondence between certain supersymmetric gauge theories and their dual supergravity descriptions. Using low-energy brane probes of the super-gravity geometries we find moduli spaces of vacua, as expected from considering the dual gauge ...

Laplacian spectrum on a nilmanifold, truncations and effective theories

Journal of High Energy Physics, 2018
Motivated by low energy effective theories arising from compactification on curved manifolds, we determine the complete spectrum of the Laplacian operator on the three-dimensional Heisenberg nilmanifold.
