Spread Complexity for Local Operator Quenches with Conserved Momentum
Ali Fatemiabhari
We study a family of locally excited states in two-dimensional conformal field theories in different setups, defined on the plane, on the cylinder, or at finite temperature. These…
Bound states and deconfinement from Romans supergravity with magnetic flux
Ali Fatemiabhari, Maurizio Piai
We apply the dictionary of gauge-gravity dualities to study the spectrum of bound states in a special one-parameter family of strongly coupled, confining field theories in four dim…

Ali Fatemiabhari, Carlos Nunez, Ricardo T. Santamaria
We study Krylov (spread) complexity in strongly coupled six-dimensional superconformal field theories with holographic duals in massive type IIA supergravity. Exte…
Krylov Complexity, Confinement and Universality
Ali Fatemiabhari, Carlos Nunez
We perform a systematic holographic study of Krylov complexity for a wide class of confining quantum field theories. Using the geometric prescription that identifies the time deriv…

Dimitrios Chatzis, Ali Fatemiabhari, Mauro Giliberti +1
This work presents a study of the entanglement entropy (EE) in a class of four-dimensional linear quiver SCFTs deformed by the presence of a VEV. We review the hologra…
On the stability of holographic confinement with magnetic fluxes
Ali Fatemiabhari, Carlos Nunez, Maurizio Piai +1
We analyze the stability properties of a simple holographic model for a confining field theory. The gravity dual consists of an Abelian gauge field, with non-trivial magnetic flux,…
Progress on Holographic Vacuum Misalignment
Ali Fatemiabhari, Daniel Elander, Maurizio Piai
We summarise highlights from an ongoing research programme that aims, in the long run, at the ambitious goal of building a realistic, complete holographic composite-Higgs model. Th…
Confinement and screening via holographic Wilson loops
Mauro Giliberti, Ali Fatemiabhari, Carlos Nunez
We present the holographic dual to a family of SCFTs in four dimensions, deformed by a VEV leading to a gapped system. We calculate Wilson loops in this system contain…
SCFT deformations via uplifted solitons
Dimitrios Chatzis, Ali Fatemiabhari, Carlos Nunez +1
A holographic method for implementing a particular supersymmetry-preserving deformation to 4d SCFTs is presented. At the heart of the procedure is a soliton solution of minimal $d=…

Daniel Elander, Ali Fatemiabhari, Maurizio Piai
We develop a bottom-up holographic model that provides the dual description of a strongly coupled field theory, in which the spontaneous breaking of an approximate global symmetry…

Dimitrios Chatzis, Ali Fatemiabhari, Carlos Nunez +1
In this paper we present three new families of smooth Type II string theory backgrounds. These are dual to supersymmetry-preserving deformations of 4d SCFTs. The deformations inclu…

Ali Fatemiabhari, Carlos Nunez
Within the electrostatic formulation of holographic duals to (balanced) conformal quivers in five and three dimensions, we study Wilson loops in antisymmetric representations. We d…
