Magnetising the $$ \mathcal{N} $$ = 4 Super Yang-Mills plasma
Bibliographic record
Abstract
Abstract 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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
