Holographic Wilsonian Renormalization and Chiral Phase Transitions

Understand

We explore the role of a holographic Wilsonian cut-off in simple probe brane models with chiral symmetry breaking/restoration phase transitions.

• The Wilsonian cut-off allows us to define supergravity solutions for off-shell configurations and hence to define a potential for the chiral condensate.
• We pay particular attention to the need for configurations whose action we are comparing to have the same IR and UV boundary conditions.
• We exhibit new first and second order phase transitions with changing cut-off.
