Carrollian bosonic supergravity at order and the universal cancellation of higher-curvature divergences
Eric Lescano
We prove that the Carrollian limit of bosonic supergravity remains finite after including the four-derivative terms arising from the -corrections, and we explicitly construct t…
Carrollian limit of NS-NS and Heterotic Supergravity
Romina Ballesteros, Eric Lescano, Sergio Patiño-López
We construct the Carrollian limit of NS--NS and heterotic supergravity through an ultra-relativistic expansion of the fields. An appropriate scaling of the dilaton renders the meas…
Lecture notes: Introduction to the Off-shell Double Copy Program
Eric Lescano
The present notes are based on a series of lectures prepared for an introductory eight-class course on the modern framework of the off-shell double copy. The course was held from A…
Kosmann derivative and momentum maps from a duality covariant framework
Romina Ballesteros, Eric Lescano, Jesús A. Rodríguez
A covariant implementation of diffeomorphisms in the presence of local symmetries is a nontrivial aspect of gravitational theories. In Double Field Theory, this is achieved through…
Curvatures and Non-metricities in the Non-Relativistic Limit of Bosonic Supergravity
Eric Lescano
We construct a metric-like formulation of the non-relativistic (NR) limit of bosonic supergravity at the Lagrangian level. This formulation is particularly useful for decomposing r…
