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…

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…

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…

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…
