Solitonic vortices and black holes with vortex hair in AdS
Roberto Auzzi, Stefano Bolognesi, Giuseppe Nardelli +2
We study soliton and black hole solutions with scalar hair in AdS in a theory with a Maxwell field and a charged scalar field with double trace boundary conditions, which can t…
On the time dependence of holographic complexity for charged AdS black holes with scalar hair
Roberto Auzzi, Stefano Bolognesi, Eliezer Rabinovici +2
In the presence of a scalar hair perturbation, the Cauchy horizon of a Reissner-Nordström black hole disappears and is replaced by the rapid collapse of the Einstein-Rosen bridge,…
Rotationally invariant isospinning baby-skyrmions dressed by fermions
Marco Barsanti, Gianni Tallarita
We couple Fermions to the isospinning (2+1) baby-skyrme model. We show that consistent rotationally invariant localised solutions can be found but the Fermionic solutions to the eq…
Dynamics of global and local vortices with orientational moduli
Minoru Eto, Adam Peterson, Fidel I. Schaposnik Massolo +1
The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for p…
Analytic Baby Skyrmions at Finite Density
Marco Barsanti, Stefano Bolognesi, Fabrizio Canfora +1
We introduce a consistent ansatz for the baby Skyrme model in (2+1)-dimensions which is able to reduce the complete set of field equations to just one equation for the profile func…
Long Way to Ricci Flatness
Jin Chen, Chao-Hsiang Sheu, Mikhail Shifman +2
We study two-dimensional weighted supersymmetric models with the goal of exploring their infrared (IR) limit. are sim…
The holographic vortex lattice using the circular cell method
Gianni Tallarita, Roberto Auzzi
We investigate vortex lattice solutions in a holographic superconductor model in asymptotically spacetime which includes the gravitational backreaction of the vortex. The c…
Vortons with Abelian and non-Abelian currents and their stability
Gianni Tallarita, Adam Peterson, Stefano Bolognesi +1
We explore vorton solutions in the Witten's model for cosmic strings and in a modified version obtained by introducing a triplet of non-Abeli…
On volume subregion complexity in Vaidya spacetime
Roberto Auzzi, Giuseppe Nardelli, Fidel I. Schaposnik Massolo +2
We study holographic subregion volume complexity for a line segment in the AdS Vaidya geometry. On the field theory side, this gravity background corresponds to a sudden quench…
The holographic non-abelian vortex
Gianni Tallarita, Roberto Auzzi, Adam Peterson
We study a fully back-reacted non-abelian vortex solution in an extension of the holographic superconductor setup. The thermodynamic properties of the vortex are computed. We show…
SU(2) Chern-Simons Theory Coupled to Competing Scalars
J. M. Pérez Ipiña, F. A. Schaposnik, G. Tallarita
We study a spontaneously broken SU(2) Chern-Simons-Higgs model coupled though a Higgs portal to an uncharged triplet scalar with a vacuum state competing with the Higgs one. We fin…
A Simple Model for a Dual Non-Abelian Monopole-Vortex Complex
Gianni Tallarita, Adam Peterson
We investigate the flux-tube joining two equal and opposite electric charges using the dual Ginzburg-Landau model of superconductivity. The model is supplemented with an additional…
Non-Abelian vortex lattices
Gianni Tallarita, Adam Peterson
We perform a numerical study of the phase diagram of the model proposed in \cite{Shifman:2012vv}, which is a simple model containing non-Abelian vortices. As per the case of Abriko…
Multi-Skyrmions on , Rational maps and Popcorn Transitions
Gianni Tallarita, Fabrizio Canfora
By combining two different techniques to construct multi-soliton solutions of the (3+1)-dimensional Skyrme model, the generalized hedgehog and the rational map ansatz, we find mult…
Multi-Skyrmions with orientational moduli
Fabrizio Canfora, Gianni Tallarita
We analyze the mechanism of condensation of orientational moduli (as introduced in [25]) on multi-Skyrmionic configurations of the four-dimensional Skyrme model. The present analys…
Visible and hidden sectors in a model with Maxwell and Chern-Simons gauge dynamics
Edwin Ireson, Fidel A. Schaposnik, Gianni Tallarita
We study a gauge theory discussing its vortex solutions and supersymmetric extension. In our set-upon the dynamics of one of two Abelian gauge fields is governed…
String pair production in non homogeneous backgrounds
Stefano Bolognesi, Eliezer Rabinovici, Gianni Tallarita
We consider string pair production in non homogeneous electric backgrounds. We study several particular configurations which can be addressed with the Euclidean world-sheet instant…
Non-Abelian Vortices in Holographic Superconductors
Gianni Tallarita
We find, by an appropriate extension of the standard holographic superconductor setup, static bulk solutions which describe holographic duals to non-Abelian vortices. In the core o…
Spin vortices in the Abelian-Higgs model with cholesteric vacuum structure
Adam Peterson, Mikhail Shifman, Gianni Tallarita
We continue the study of vortices with cholesteric vacuum structure. A new class of solutions is found which represent global vortices of the internal spin field. These spin…
Chern-Simons-Higgs Theory with Visible and Hidden Sectors and its SUSY Extension
Paola Arias, Edwin Ireson, Fidel A. Schaposnik +1
We study vortex solutions in Abelian Chern-Simons-Higgs theories with visible and hidden sectors. We first consider the case in which the two sectors are connected through a BF-lik…

Mikhail Shifman, Gianni Tallarita, Alexei Yung
We extend the Georgi-Glashow model of the t'Hooft-Polyakov monopoles to include additional collective coordinates "orientational isospin moduli". The low-energy theory of these sol…
Confining Strings in Supersymmetric Theories with Higgs Branches
Mikhail Shifman, Gianni Tallarita, Alexei Yung
We study flux tubes (strings) on the Higgs branches in supersymmetric gauge theories. In generic vacua on the Higgs branches strings were shown to develop long-range "tails" associ…
Low energy dynamics of vortices in systems with cholesteric vacuum structure
Adam Peterson, Mikhail Shifman, Gianni Tallarita
We discuss flux tubes in systems with gauge, and spin-orbit locked symmetry. The spin-orbit locking is achieved explicitly in the Lagrangian by introducing a p…
