Three-dimensional non-relativistic supergravity and torsion
Patrick Concha, Lucrezia Ravera, Evelyn Rodríguez
In this paper we present a torsional non-relativistic Chern-Simons teleparallel (super)gravity theory in three spacetime dimensions. We start by developing the non-relativistic lim…
On the hidden symmetries of supergravity
Lucrezia Ravera
We report on recent developments regarding the supersymmetric Free Differential Algebra describing the vacuum structure of supergravity. We focus on the emergence of a hidde…
Metric-Affine Vector-Tensor Correspondence and Implications in gravity
Damianos Iosifidis, Ratbay Myrzakulov, Lucrezia Ravera +2
We extend the results of antecedent literature on quadratic Metric-Affine Gravity by studying a new quadratic gravity action in vacuum which, besides the usual (non-Riemannian) Ein…
On the geometric approach to the boundary problem in supergravity
Laura Andrianopoli, Lucrezia Ravera
We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presen…
Cosmology of Quadratic Metric-Affine Gravity
Damianos Iosifidis, Lucrezia Ravera
We investigate the cosmological aspects of the most general parity preserving Metric-Affine Gravity theory quadratic in torsion and non-metricity in the presence of a cosmological…
Metric-Affine Myrzakulov Gravity Theories
N. Myrzakulov, R. Myrzakulov, L. Ravera
In this paper we review the Myrzakulov Gravity models (MG-N, with ) and derive their respective metric-affine generalizations (MAMG-N), discussing…
Twisting D(2,1; α) Superspace
L. Andrianopoli, B. L. Cerchiai, R. Matrecano +3
We develop a three-dimensional theory of rigid supersymmetry describing the dynamics of a set of hypermultiplets on a curved AdS…
Three-dimensional Maxwellian Carroll gravity theory and the cosmological constant
Patrick Concha, Diego Peñafiel, Lucrezia Ravera +1
In this work, we present the three-dimensional Maxwell Carroll gravity by considering the ultra-relativistic limit of the Maxwell Chern-Simons gravity theory defined in three space…
Three-dimensional exotic Newtonian supergravity theory with cosmological constant
Patrick Concha, Lucrezia Ravera, Evelyn Rodríguez
We present a supersymmetric extension of the exotic Newtonian Chern-Simons gravity theory in three spacetime dimensions. The underlying new non-relativistic superalgebra is obtaine…
The Cosmology of Quadratic Torsionful Gravity
Damianos Iosifidis, Lucrezia Ravera
We study the cosmology of a quadratic metric-compatible torsionful gravity theory in the presence of a perfect hyperfluid. The gravitational action is an extension of the Einstein-…
Conformal gravity with totally antisymmetric torsion
Riccardo D'Auria, Lucrezia Ravera
We present a gauge theory of the conformal group in four spacetime dimensions with a non-vanishing torsion. In particular, we allow for a completely antisymmetric torsion, equivale…
