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…
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…
A Non-Relativistic Limit for Heterotic Supergravity and its Gauge Lagrangian
Eric Lescano
Motivated by the recent construction of non-relativistic (NR) heterotic Double Field Theory (HDFT), we analyze the bosonic sector of heterotic supergravity under a consisten…
Non-closed scalar charge in four-dimensional Einstein-scalar-Gauss-Bonnet black hole thermodynamics
Romina Ballesteros, Marcela Cárdenas, Eric Lescano
We develop a covariant differential-form framework to define scalar charges for stationary, asymptotically flat black holes in --dimensional Einstein-scalar-Gauss-Bonnet gravity…
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…
