Event details

Higher spins, entanglement and time dependence in CFT_2/AdS_3

 

We review some universal aspects of Renyi entropies of entanglement, in equilibrium and with local quenches, in 2d CFTs with W-symmetry, in the presence of chemical potentials for higher spin charge. We explain how these results are nontrivially reproduced by bulk higher spin black holes in the Chern-Simons formulation of higher spins on AdS_3. We use the bulk formulation to show that bounds on the scrambling time are violated in the presence of higher spin charge, and present some CFT results on scrambling time in the presence of higher spin chemical potentials.
