Non-Relativistic Chern-Simons Supergravity with Torsion
Francisco Barriga, Patrick Concha, Nelson Merino +1
In this work, we construct a three-dimensional non-relativistic Chern--Simons supergravity theory with both curvature and torsion within the Mielke--Baekler framework. We show that…

Torsional Carroll Gravity
P. Concha, N. Merino, L. Ravera +1
The ultra-relativistic (Carrollian) regime of gravity has recently emerged as a fertile framework for exploring holography, non-Lorentzian symmetries, and geometric limit of Genera…

Inhomogeneous metrics on complex bundles in Lovelock gravity
Cristóbal Corral, Borja Diez, Daniel Flores-Alfonso +2
We consider Lovelock gravity in arbitrary, even dimensions. We find a large class of new gravitational instantons by considering extended nontrivial circle bundles over Kähler man…
