Abstract We study the superconformal index of 3d N $$ \mathcal{N} $$ = 2 superconformal field theories on S 1 × ω S 2 in the Cardy-like limit where the radius of the S 1 is much smaller than that of the S 2. We show that the first two leading terms

Abstract We study the logarithmic corrections to various CFT partition functions in the context of the AdS4/CFT3 correspondence for theories arising on the worldvolume of M2-branes. We utilize four-dimensional gauged supergravity and heat kernel meth

Abstract We use holography in conjunction with recent results from supersymmetric localization to compute certain thermal observables for 3d N $$ \mathcal{N} $$ = 2 holographic SCFTs arising on the worldvolume of N M2-branes. We obtain results for th

Abstract We study the S 1 × Σ g $$ {\Sigma}_{\mathfrak{g}} $$ topologically twisted index and the squashed sphere partition function of various 3d N $$ \mathcal{N} $$ ≥ 2 holographic superconformal field theories arising from M2-branes. Employing

Abstract We study the large N limit of some supersymmetric partition functions of the U(N) k × U(N) −k ABJM theory computed by supersymmetric localization. We conjecture an explicit expression, valid to all orders in the large N limit, for the par

Abstract We study a limit of the superconformal index of the ABJM theory on S 1 × S 2 in which the size of the circle is much smaller than the radius of the two-sphere. We derive closed form expressions for the two leading terms in this Cardy-like l

Abstract We study four-derivative corrections to 5d N $$ \mathcal{N} $$ = 2 minimal gauged supergravity using tools from conformal supergravity. There are two supersymmetric invariants at the four-derivative order and we show explicitly how to write

We calculate quantum corrections to the entropy of four-dimensional de Sitter space induced by higher-derivative terms in the gravitational action and by one-loop effects. Employing the intertwinement in semiclassical gravity of Euclidean de Sitter a

Abstract We use the Atiyah-Singer index theorem to derive the general form of the one-loop corrections to observables in asymptotically anti-de Sitter (AdS4) supersymmetric backgrounds of abelian gauged supergravity. Using the method of supergravity

Abstract We use conformal supergravity techniques to study four-derivative corrections in four-dimensional gauged supergravity. We show that the four-derivative Lagrangian for the propagating degrees of freedom of the N $$ \mathcal{N} $$ = 2 gravity
