  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.
