Dyonic Black Hole and Holography

Understand

We study thermodynamic properties of dyonic black hole and its dual field theory.

• We observe that the phase diagram of a dyonic black hole in constant electric potential and magnetic charge ensemble is similar to that of a Van der Waals fluid with chemical potential.
• Phase transitions and other critical phenomena have been studied in presence of magnetic charge and chemical potential.
• We also analyse magnetic properties of dual conformal field theory and observe a ferromagnetic like behavior of boundary theory when the external magnetic field vanishes.
