Small Black holes vs horizonless solutions in AdS

الأصل · EN

It is argued that the appropriate macroscopic description of half-BPS mesonic chiral operators in generic d=4 N=1 toric gauge theories is in terms of the geometric quantization of smooth horizonless configurations. The relevance of different ensemble macroscopic descriptions is emphasized: lorentzian vs euclidean configurations as (semiclassical) microstates vs saddle points in an euclidean path integral.
