In a large-N 1D Yukawa-SYK strange metal, the fermionic second Rényi entropy obeys a CFT-like scaling curve with effective central charge c_eff ≈ 1.6 and a finite fermion-boson entanglement length ℓ0 at T=0.

Entanglement entropy of fermions in a strange metal
In a large-N 1D Yukawa-SYK strange metal, the fermionic second Rényi entropy obeys a CFT-like scaling curve with effective central charge c_eff ≈ 1.6 and a finite fermion-boson entanglement length ℓ0 at T=0.
