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…
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…
Bounding interventional queries from generalized incomplete contingency tables
Ivano Lodato, Aditya V. Iyer, Isaac Z. To
We introduce a method for evaluating interventional queries and Average Treatment Effects (ATEs) in the presence of generalized incomplete contingency tables (GICTs), contingency t…
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…
On partial information retrieval: the unconstrained 100 prisoner problem
Ivano Lodato, Snehal M. Shekatkar, Tian An Wong
We consider a generalization of the classical 100 Prisoner problem and its variant, involving empty boxes, whereby winning probabilities for a team depend on the number of attempts…
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…

We consider the maximal extended supergravity theory in 3 dimensions with fermionic generators transforming under real but non necessarily irreducible representations of…
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…
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…
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…
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…
Mapping Fermion and Boson systems onto the Fock space of harmonic oscillators
Vincenzo Branchina, Marco Di Liberto, Ivano Lodato
The fluctuation-dissipation theorem (FDT) is very general and applies to a broad variety of different physical phenomena in condensed matter physics. With the help of the FDT and f…
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…
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…
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…

We study supersymmetric extensions of the three dimensional BMS algebra (BMS) with most generic possible central extensions. We find that -extended supersymmetri…
Logistic growth on networks: exact solutions for the SI model
Wout Merbis, Ivano Lodato
The SI model is the most basic of all compartmental models used to describe the spreading of information through a population. Despite its apparent simplicity, the analytic solutio…
Synchronization Properties of Network Motifs
Ivano Lodato, Stefano Boccaletti, Vito Latora
We address the problem of understanding the variable abundance of 3-node and 4-node subgraphs (motifs) in complex networks from a dynamical point of view. As a criterion in the det…
Dark energy and Josephson junctions
Vincenzo Branchina, Marco Di Liberto, Ivano Lodato
It has been recently claimed that dark energy can be (and has been) observed in laboratory experiments by measuring the power spectrum of the noise current in a resistive…
