A Holographic Model of Quantum Hall Transition
Andrea Mezzalira, Andrei Parnachev
We consider a phenomenological holographic model, inspired by the D3/D7 system with a 2+1 dimensional intersection, at finite chemical potential and magnetic field. At large 't Hoo…
Analytic pseudo-Goldstone bosons
Riccardo Argurio, Andrea Marzolla, Andrea Mezzalira +1
We consider the interplay between explicit and spontaneous symmetry breaking in strongly coupled field theories. Some well-known statements, such as the Gell-Mann-Oakes-Renner rela…
A Note on Holographic Non-Relativistic Goldstone Bosons
Riccardo Argurio, Andrea Marzolla, Andrea Mezzalira +1
We consider a holographic set-up where relativistic invariance is broken by a chemical potential, and a non-abelian internal symmetry is broken spontaneously. We use the tool of ho…
Electromagnetic response of strongly coupled plasmas
Davide Forcella, Andrea Mezzalira, Daniele Musso
We present a thorough analysis of the electromagnetic response of strongly coupled neutral plasmas described by the gauge/gravity correspondence. The coupling of the external elect…
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…
Fermionic variations on AdS/CFT themes
Andrea Mezzalira
This thesis aims to explore the effects caused by the presence of Grassmann numbers in two different frameworks derived from AdS/CFT correspondence: purely fermionic sigma-models a…
Fermions, Wigs, and Attractors
L. G. C. Gentile, P. A. Grassi, A. Marrani +1
We compute the modifications to the attractor mechanism due to fermionic corrections. In N=2, D=4 supergravity, at the fourth order, we find a new contribution to the horizon value…
Fermionic Corrections to Fluid Dynamics from BTZ Black Hole
L. G. C. Gentile, P. A. Grassi, A. Mezzalira
We reconstruct the complete fermionic orbit of the non-extremal BTZ black hole by acting with finite supersymmetry transformations. The solution satisfies the exact supergravity eq…
Fermionic Wigs for BTZ Black Holes
L. G. C. Gentile, P. A. Grassi, A. Mezzalira
We compute the wig for the BTZ black hole, namely the complete non-linear solution of supergravity equations with all fermionic zero modes. We use a "gauge completion" method start…
Fermionic Wigs for AdS-Schwarzschild Black Holes
L. G. C. Gentile, P. A. Grassi, A. Mezzalira
We provide the metric, the gravitino fields and the gauge fields to all orders in the fermionic zero modes for D=5 and D=4, N=2 gauged supergravity solutions starting from non-extr…
BCJ and KK Relations from BRST Symmetry and Supergravity Amplitudes
P. A. Grassi, A. Mezzalira, L. Sommovigo
We use Pure Spinor string theory to construct suitable kinematical factors which explicitly satisfy the Kleiss-Kuijf (KK) relations. Using the formula conceived by Bern et al. and…
Supersymmetric Fluid Dynamics
P. A. Grassi, A. Mezzalira, L. Sommovigo
Recently Navier-Stokes (NS) equations have been derived from the duality between the black branes and a conformal fluid on the boundary of AdS_5. Nevertheless, the full corresponde…
Fluid Super-Dynamics from Black Hole Superpartners
L. G. C. Gentile, P. A. Grassi, A. Mezzalira
Recently the Navier-Stokes equations have been derived from the duality with the black branes in AdS_5. The zero modes of black branes are reinterpreted as dynamical degrees of fre…
Aspects of Quantum Fermionic T-duality
P. A. Grassi, A. Mezzalira
We study two aspects of fermionic T-duality: the duality in purely fermionic sigma models exploring the possible obstructions and the extension of the T-duality beyond classical ap…
