Physical Review Letters, 2022 Minimal massive gravity in three dimensions propagates a single massive spin-2 mode around an AdS vacuum. It is distinguished by allowing for vacua with positive central charges of the asymptotic conformal algebra and a bulk graviton of positive energy.

Cosmological Constant in SUGRA Models with Degenerate Vacua
Universe, 2019 The extrapolation of couplings up to the Planck scale within the standard model (SM) indicates that the Higgs effective potential can have two almost degenerate vacua, which were predicted by the multiple point principle (MPP). The application of the MPP

On jordanian deformations of AdS5 and supergravity [PDF]
, 2016 We consider various homogeneous Yang–Baxter deformations of the AdS 5 × S 5 superstring that can be obtained from the η-deformed superstring and related models by singular boosts. The jordanian deformations we obtain in this way behave similarly to the η-

Newton-Cartan supergravity with torsion and Schrödinger supergravity [PDF]
Journal of High Energy Physics, 2015 We derive a torsionfull version of three-dimensional N=2 Newton-Cartan supergravity using a non-relativistic notion of the superconformal tensor calculus. The "superconformal" theory that we start with is Schr dinger supergravity which we obtain by gauging the Schr dinger superalgebra. We present two non-relativistic N=2 matter multiplets that can be

Higher derivative couplings and massive supergravity in three dimensions
, 2015 We develop geometric superspace settings to construct arbitrary higher derivative couplings (including R^n terms) in three-dimensional supergravity theories with N=1,2,3 by realising them as conformal supergravity coupled to certain compensators. For all

Scale invariant Volkov-Akulov Supergravity [PDF]
, 2015 A scale invariant Goldstino theory coupled to Supergravity is obtained as a standard supergravity dual of a rigidly scale invariant higher--curvature Supergravity with a nilpotent chiral scalar curvature.

Fundamental Supermultiplet in Twelve Dimensions
Frontiers in Physics, 2018 We discuss a set of local fields which provide the on-shell massless states expected for the fundamental linear representation of supersymmetry in twelve dimensions.

A Lax Operator for $d=2$ $N=2$ Supergravity [PDF]
arXiv, 2021 General relativity and supergravity become integrable systems after dimensional reduction to two spacetime dimensions. This means the equations of motion can be encoded in the flatness condition for a Lax operator. Nicolai and Warner found Lax operators for dimensionally reduced supergravity.

Lectures on Supergravity [PDF]
Fortschritte der Physik, 2002 The text is an essentially self-contained introduction to four-dimensional N=1 supergravity, including its couplings to super Yang-Mills and chiral matter multiplets, for readers with basic knowledge of standard gauge theories and general relativity. Emphasis is put on showing how supergravity fits in the general framework of gauge theories and how it ...

On N = 2 Truncations of IIB on T^{1,1} [PDF]
, 2012 We study the N=4 gauged supergravity theory which arises from the consistent truncation of IIB supergravity on the coset T^{1,1}. We analyze three N=2 subsectors and in particular we clarify the relationship between true superpotentials for gauged ...
