One-loop determinants for black holes in 4d gauged supergravity
Kiril Hristov, Ivano Lodato, Valentin Reys
We continue the effort of defining and evaluating the quantum entropy function for supersymmetric black holes in 4d gauged supergravity, initiated in [1803.05920]. T…
Maximally -extended super-BMS algebras and Generalized 3D Gravity Solutions
Nabamita Banerjee, Arindam Bhattacharjee, Ivano Lodato +1
We consider the maximal extended supergravity theory in 3 dimensions with fermionic generators transforming under real but non necessarily irreducible representations of…
Supersymmetric Galilean conformal blocks
Ivano Lodato, Wout Merbis, Zodinmawia
We set up the bootstrap procedure for supersymmetric Galilean Conformal (SGC) field theories in two dimensions by constructing the SGC blocks in the and two possibl…
On the quantum entropy function in 4d gauged supergravity
Kiril Hristov, Ivano Lodato, Valentin Reys
We analyze BPS black hole attractors in the conformal 4d gauged supergravity formalism and apply the technique known as supergravity localization in order to evaluate Sen's quantum…
dilaton Weyl multiplet in 4D supergravity
Daniel Butter, Subramanya Hegde, Ivano Lodato +1
We construct the dilaton Weyl multiplet for conformal supergravity in four dimensions. Beginning from an on-shell vector multiplet coupled to the standard Weyl multiplet, the…
A 24+24 real scalar multiplet in four dimensional N=2 conformal supergravity
Subramanya Hegde, Ivano Lodato, Bindusar Sahoo
Starting from the 48+48 component multiplet of supercurrents for a rigid N=2 tensor multiplet in four spacetime dimensions, we obtain the transformation of the linearized supergrav…
N=4 Supersymmetric BMS3 algebras from asymptotic symmetry analysis
Nabamita Banerjee, Ivano Lodato, Turmoli Neogi
We consider three dimensional flat supergravity, with an abelian R-symmetry enhancing the gravitational phase space. We obtain the field configuration whose asymptotic symmet…
Super-BMS algebras from flat supergravities
Ivano Lodato, Wout Merbis
We consider two possible flat space limits of three dimensional AdS supergravity. They differ by how the supercharges are scaled with the AdS radius : t…
Extended Supersymmetric BMS algebras and Their Free Field Realisations
Nabamita Banerjee, Dileep P. Jatkar, Ivano Lodato +2
We study supersymmetric extensions of the three dimensional BMS algebra (BMS) with most generic possible central extensions. We find that -extended supersymmetri…
Higher derivative corrections to BPS black hole attractors in 4d gauged supergravity
Kiril Hristov, Stefanos Katmadas, Ivano Lodato
We analyze BPS black hole attractors in 4d gauged supergravity in the presence of higher derivative supersymmetric terms, including a Weyl-squared-type action, and determine the re…
The Resolution of an Entropy Puzzle for 4D non-BPS Black Holes
Nabamita Banerjee, Sukruti Bansal, Ivano Lodato
We show the equality between macroscopic and microscopic black hole entropy for a class of four dimensional non-supersymmetric black holes in supergravity theory, up t…
Rigid 4D N=2 supersymmetric backgrounds and actions
Daniel Butter, Gianluca Inverso, Ivano Lodato
We classify all N=2 rigid supersymmetric backgrounds in four dimensions with both Lorentzian and Euclidean signature that preserve eight real supercharges, up to discrete identific…
Non-renormalization theorems and N=2 supersymmetric backgrounds
Daniel Butter, Bernard de Wit, Ivano Lodato
The conditions for fully supersymmetric backgrounds of general N=2 locally supersymmetric theories are derived based on the off-shell superconformal multiplet calculus. This enable…
New higher-derivative invariants in N=2 supergravity and the Gauss-Bonnet term
Daniel Butter, Bernard de Wit, Sergei M. Kuzenko +1
A new class of N=2 locally supersymmetric higher-derivative invariants is constructed based on logarithms of conformal primary chiral superfields. They characteristically involve a…
The fate of flat directions in higher derivative gravity
Nabamita Banerjee, Suvankar Dutta, Ivano Lodato
We discuss the fate of flat directions in higher derivative gravity by studying two explicit examples, namely higher derivative gauged supergravity in five dimensions and higher de…
