Elliptical Wilson loops in Super Yang-Mills
Thales Azevedo, Alfonso Ballon-Bayona, Leonardo Pazito
We investigate elliptical Wilson loops in Super Yang--Mills theory at weak and strong coupling for small values of the eccentricity. We obtain analytical results for t…
Transport coefficients and quasinormal modes in Einstein-dilaton holographic QCD
Nairy A. Villarreal, Luis A. H. Mamani, Alfonso Ballon-Bayona +2
In this paper, we investigate the transport coefficients of a strongly coupled plasma in the context of holographic QCD models based on Einstein-dilaton gravity that are compatible…
Thermodynamics and DC conductivity of 2D anisotropic fluids from axion holography
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate a strongly coupled finite-density anisotropic fluid in dimensions dual to an asymptotically AdS black brane that is a solution of Einstein-Maxwell-Axion theory…
Magnetising the Super Yang-Mills plasma
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the thermodynamics of the anisotropic magnetic black brane solution found by D'Hoker and Kraus arXiv:0908.3875. This solution is the gravity dual of a st…
Effective holographic models for QCD: Thermodynamics and viscosity coefficients
Alfonso Ballon-Bayona, Luis A. H. Mamani, Alex S. Miranda +1
A finite temperature extension of the effective holographic models for QCD (EHQCD), proposed in Ref.[1], is investigated in the present work. EHQCD models are characterized by two…
Criticality from Einstein-Maxwell-dilaton holography at finite temperature and density
Alfonso Ballon-Bayona, Henrique Boschi-Filho, Eduardo Folco Capossoli +1
We investigate consistent charged black hole solutions to the Einstein-Maxwell-Dilaton (EMD) equations that are asymptotically AdS. The solutions are gravity duals to phases of a n…
Magnetic catalysis and the chiral condensate in holographic QCD
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the effect of a non-zero magnetic field on the chiral condensate using a holographic QCD approach. We extend the model proposed by Iatrakis, Kiritsis and Paredes in…
An effective holographic approach to QCD
Alfonso Ballon-Bayona, Henrique Boschi-Filho, Luis A. H. Mamani +2
We describe a holographic approach to QCD where conformal symmetry is broken explicitly in the UV by a relevant operator . The operator maps to a 5d scalar field, the dil…
Effective holographic models for QCD: glueball spectrum and trace anomaly
Alfonso Ballon-Bayona, Henrique Boschi-Filho, Luis A. H. Mamani +2
We investigate effective holographic models for QCD arising from five dimensional Dilaton-Gravity. The models are characterized by a dilaton with a mass term in the UV, dual to a C…
A universal order parameter for Inverse Magnetic Catalysis
Alfonso Ballon-Bayona, Matthias Ihl, Jonathan P. Shock +1
We revisit the chiral transition in the finite density Sakai-Sugimoto model and find that, at fixed temperature , the magnetisation near the critical line acts as an or…
Holographic deconfinement transition in the presence of a magnetic field
Alfonso Ballon-Bayona
We investigate the thermodynamics of the flavour sector of the Sakai-Sugimoto model in the presence of a magnetic field. Renormalizing the euclidean Dirac-Born-Infeld action in the…
DBI equations and holographic DC conductivity
Alfonso Ballon-Bayona, Cristine N. Ferreira, Victor J. Vasquez Otoya
We provide a simple method for writing the Dirac-Born-Infeld (DBI) equations of a Dp-brane in an arbitrary static background whose metric depends only on the holographic radial coo…
A chiral magnetic spiral in the holographic Sakai-Sugimoto model
Alfonso Ballon-Bayona, Kasper Peeters, Marija Zamaklar
We investigate the effect of a magnetic field on the vacuum of low-temperature QCD at large-N_c in the presence of a chiral chemical potential, using the holographic Sakai-Sugimoto…
