Instability of a magnetized QGP sourced by a scalar operator
Abstract We use the gauge/gravity correspondence to study the thermodynamics of a magnetized quark-gluon plasma in the presence of a scalar operator of dimension Δ = 2. We proceed by working in a five-dimensional gauged supergravity theory, where we numerically construct an asymptotically AdS5 backg...
