Twin conformal field theories
L. Borsten, M. J. Duff, A. Marrani
Supersymmetric theories with the same bosonic content but different fermions, aka \emph{twins}, were thought to exist only for supergravity. Here we show that pairs of super confor…
Holographic correlators in AdS
Stefano Giusto, Rodolfo Russo, Congkao Wen
We derive the four-point correlators of scalar operators of dimension one in the supergravity limit of the D1D5 CFT holographically dual to string theory on AdS$_3\times S^3\times…
Three-charge superstrata with internal excitations
Elaheh Bakhshaei, Alessandro Bombini
We construct a new family of three-charge BPS smooth solutions that have the same charges as the supersymmetric D1D5P Black Hole and are non-invariant under rotations…
Microscopic origin of the Bekenstein-Hawking entropy of supersymmetric AdS black holes
Alejandro Cabo-Bizet, Davide Cassani, Dario Martelli +1
We present a holographic derivation of the entropy of supersymmetric asymptotically AdS black holes. We define a BPS limit of black hole thermodynamics by first focussing on a…
On the dynamical origin of parameters in Supersymmetry
Niccolò Cribiori, Stefano Lanza
We formulate global supersymmetric Lagrangians of self-interacting vector multiplets in terms of variant multiplets, whose non-propagating fields are replaced with…
Timelike structures of ten-dimensional supersymmetry
Andrea Legramandi, Luca Martucci, Alessandro Tomasiello
In several contexts, supersymmetry can be reformulated in terms of calibrations, namely forms whose integrals measure minimal energies. It has been conjectured that this should be…
Feynman Integrals and Intersection Theory
Pierpaolo Mastrolia, Sebastian Mizera
We introduce the tools of intersection theory to the study of Feynman integrals, which allows for a new way of projecting integrals onto a basis. In order to illustrate this techni…
Squashing the Boundary of Supersymmetric AdS Black Holes
Davide Cassani, Lorenzo Papini
We construct new supersymmetric black holes in five-dimensional supergravity with an arbitrary number of vector multiplets and Fayet-Iliopoulos gauging. These are asymptotically lo…
A note on the Virasoro blocks at order
Alessandro Bombini, Stefano Giusto, Rodolfo Russo
We derive an explicit expression for the contribution to the Virasoro blocks in 2D CFT in the limit of large with fixed values of the operators' dimensions. We follow the…
Non-Commutativity effects in the Dirac equation in crossed electric and magnetic fields
D. Nath, M. Presilla, O. Panella +1
In this paper we present exact solutions of the Dirac equation on the non-commutative plane in the presence of crossed electric and magnetic fields. In the standard commutative pla…
Can Chern-Simons or Rarita-Schwinger be a Volkov-Akulov Goldstone?
Sukruti Bansal, Dmitri Sorokin
We study three-dimensional non-linear models of vector and vector-spinor Goldstone fields associated with the spontaneous breaking of certain higher-spin counterparts of supersymme…
AC conductivities of a holographic Dirac semimetal
Gianluca Grignani, Andrea Marini, Lorenzo Papini +1
We use the AdS/CFT correspondence to compute the AC conductivities for a (2+1)-dimensional system of massless fundamental fermions coupled to (3+1)-dimensional Super Yang-Mills the…
AdS Vacuum Bubbles, Holography and Dual RG Flows
Riccardo Antonelli, Ivano Basile, Alessandro Bombini
We explore the holographic properties of non-perturbative vacuum decay in Anti-de Sitter () geometries. To this end, we consider a gravitational theory in a metastabl…
Chromo-Natural inflation in Supergravity
Gianguido Dall'Agata
We present supergravity realizations of chromo-natural inflationary models. We show that by using superpotentials with "imaginary" holomorphic functions of the inflaton one can obt…
Holographic RG Flows for Four-dimensional SCFTs
Nikolay Bobev, Davide Cassani, Hagen Triendl
We study holographic renormalization group flows from four-dimensional SCFTs to either or SCFTs. Our approach is based on the framew…
A Borcherds-Kac-Moody superalgebra with Conway symmetry
Sarah M. Harrison, Natalie M. Paquette, Roberto Volpato
We construct a Borcherds Kac-Moody (BKM) superalgebra on which the Conway group Co acts faithfully. We show that the BKM algebra is generated by the BRST-closed states in a chi…
On the off-shell formulation of N=2 supergravity with tensor multiplets
Niccolò Cribiori, Gianguido Dall'Agata
We revisit the construction of N=2 superconformal multiplets using rheonomic superspace techniques. We apply the result to the derivation of off-shell Poincaré supersymmetric model…
Three-forms, dualities and membranes in four-dimensional supergravity
Igor Bandos, Fotis Farakos, Stefano Lanza +2
We consider four-dimensional supergravity models of a kind appearing in string flux compactifications. It has been recently shown that, by using double three-form m…
Supersymmetric Reducible Higher-Spin Multiplets in Various Dimensions
Dmitri Sorokin, Mirian Tsulaia
We construct, in D=3,4,6 and 10 space-time dimensions, supersymmetric Lagrangians for free massless higher spin fields which belong to reducible representations of the Poincare gro…
