Deformations through BRST Symmetry
Elia de Sabbata, Pietro Antonio Grassi, Massimo Porrati
We study the deformation using its formulation as a CFT coupled to two-dimensional dynamical gravity. Working within the BRST formalism, we apply the intertwiner construc…
Supergravity Actions with Integral Forms
L. Castellani, R. Catenacci, P. A. Grassi
Integral forms provide a natural and powerful tool for the construction of supergravity actions. They are generalizations of usual differential forms and are needed for a consisten…
No Fermionic Wigs for BPS Attractors in 5 Dimensions
Lorenzo G. C. Gentile, Pietro A. Grassi, Alessio Marrani +2
We analyze the fermionic wigging of 1/2-BPS (electric) extremal black hole attractors in N=2, D=5 ungauged Maxwell-Einstein supergravity theories, by exploiting anti-Killing spinor…
Pure Spinor Integration from the Collating Formula
Pietro Antonio Grassi, Luca Sommovigo
We use the technique developed by Becchi and Imbimbo to construct a well-defined BRST-invariant path integral formulation of pure spinor amplitudes. The space of pure spinors can b…
Quantum Computing with Superqubits
Leonardo Castellani, Pietro Antonio Grassi, Luca Sommovigo
We analyze some aspects of quantum computing with super-qubits (squbits). We propose the analogue of a superfield formalism, and give a physical interpretation for the Grassmann co…
