“…Some of our main results are conveniently summarized in the phase diagram in figure 1, where we can see that the presence of the magnetic field induces a very rich thermodynamic behavior. While previously [34] we had only observed IMC for meson dissociation, we see now that the physics of the system is much more interesting, as the dependence of the phase transition on the magnetic field is highly non-trivial.…”

“…The main objective of this manuscript is to provide additional details and extend the analysis that we presented in [34]. Concretely, here we present a more in depth thermodynamic analysis and widen our study of the spectrum of mesons by considering excitations over the 3-sphere.…”

“…In [34] we presented our first results using the construction just described. We found that, in contrast to the results obtained with the setup from [27,28], the effect of the magnetic field is to decrease the critical temperature at which the mesons melt, that is, we observed IMC for meson dissociation.…”

“…We also showed that the melting can be triggered JHEP06(2020)010 at fixed temperature by adjusting the magnetic field intensity, but only for a certain range of temperatures. We named this phenomenom magnetic meson melting (MMM) in [34].…”

“…The situation changes for 0.501 < T /M < 0.765, since for this temperatures the D7-branes transition from Minkowski to black hole embeddings at a melting magnetic field intensity, which we denote b M M M /M 2 . We named this phenomenom magnetic meson melting (MMM) in [34], because what happens from the dual theory perspective is that the mesons are being melted at a fixed temperature by increasing the magnetic field only. For higher values of the temperature, namely T /M > 0.765, only black hole embeddings exist regardless of the magnetic field intensity.…”

We extend our analysis of holographic meson dissociation in the presence of an intense magnetic field. In addition to the previously known critical temperature above which the mesons melt, we found that for certain magnetic field intensities there exists a second lower critical temperature, below which stable mesons cease to exist. While we showed before that there is a range of high temperatures for which mesons can be melted by changing the magnetic field intensity, here we show that, as a consequence of the second critical point, there is also a range of low temperatures for which this phenomenom, which we term Magnetic Meson Melting (MMM), can be triggered. Additionaly, we also show that the magnetic field decreases the mass gap of the meson spectrum along with their masses. We are able to observe this by constructing a configuration that makes it possible to apply gauge/gravity methods to study fundamental degrees of freedom in a quark-gluon plasma subject to a magnetic field as intense as that expected in high energy collisions. This is achieved by the confection of a ten-dimensional background that is dual to the magnetized plasma and nonetheless permits the embedding of D7-branes in it. The main difference with previous approaches, which in consequence gives the novel results, is that the magnetic field retroacts in the geometry itself, as opposed to be confined to the world volume of the probe D7-branes.

We investigate the thermodynamics of the anisotropic magnetic AdS5 black brane solution found by D’Hoker and Kraus [1]. This solution is the gravity dual of a strongly coupled $$ \mathcal{N} $$ N = 4 Super Yang-Mills plasma in ℝ3, 1, with temperature T, in the presence of a magnetic field $$ \mathcal{B} $$ B . Following the procedure of holographic renormalisation we calculate the Gibbs free energy and the holographic stress tensor of the conformal plasma. We evaluate several thermodynamic quantities including the magnetisation, the anisotropic pressures and the speeds of sound. Our results are consistent with an RG flow from a perturbed AdS5 black brane at small $$ \mathcal{B} $$ B /T2 to a BTZ × ℝ2 black brane at large $$ \mathcal{B} $$ B /T2. We also perform a phenomenological analysis where we compare the thermodynamics of a magnetised conformal plasma against the lattice QCD results for the thermodynamics of the magnetised quark-gluon plasma.
