Singular black holes and chiral 1+1 cosets from N=4 SYM

I discuss a conjectured method of obtaining a (chiral) “strange metal” coset SU(N)_N*SU(N)_N/SU(N)_{2N} from the fermionic PSU(1|1) sector of {\cal N=4} SYM. The construction suggests that the gravitational dual to the coset is the near horizon limit of a specific singular degeneration of a fast rotating black hole in AdS_5.
