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…
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…
Gravitational four-derivative corrections in non-relativistic heterotic supergravity and the Green-Schwarz mechanism
Eric Lescano
We present the first explicit construction of the four-derivative gravitational corrections to heterotic supergravity in the non-relativistic (NR) limit. By extending the Bergshoef…
Trivialization of the gravitational Green-Schwarz transformation in the non-relativistic limit of string theory
Eric Lescano
We show that the gravitational Green-Schwarz (GS) transformation becomes trivial in the non-relativistic (NR) limit of ten-dimensional heterotic supergravity with four-derivative c…
The non-relativistic limit of HSZ Theory
Eric Lescano
We study the non-relativistic (NR) limit of HSZ theory, a higher-derivative theory of gravity with exact and manifest T-duality invariance. Since the theory can be formulated using…
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…
On the inclusion of statistical matter in the non-relativistic limit of NS-NS supergravity
Eric Lescano
We combine techniques from kinetic theory and string dualities to couple statistical matter to a non-relativistic (NR) supergravity background, enabling the theory to be formulated…
