Chiral transition and meson melting within improved holographic soft wall models
Alfonso Ballon-Bayona, Sean Bartz, Luis A. H. Mamani +1
We describe the chiral transition for the quark condensate and the melting of scalar and vector mesons in two-flavor holographic QCD. This is done by extending the improved hologra…

Saulo M. Diles, Alex S. Miranda, Luis A. H. Mamani +2
The motion of water is governed by the Navier-Stokes equations, which are complemented by the continuity equation to ensure local mass conservation. In this work, we construct the…

A holographic model is used to investigate the thermodynamics and the phase diagram of a heavy quarks system. From such a model we obtain an equation of state and explore its appli…
