Chiral Symmetry Breaking and Restoration in (2+1) Dimensions from Holography: Magnetic and Inverse Magnetic Catalysis

Understand

We study the chiral symmetry breaking and restoration in $ (2+1) $-dimensional gauge theories from the holographic hard and softwall models.

• We describe the behavior of the chiral condensate in the presence of an external magnetic field for both models at finite temperature.
• For the hardwall model we find Magnetic Catalysis (MC) in different set ups.
• For the softwall model we find Inverse Magnetic Catalysis (IMC) and MC in different situations.
