    Exact results for corner contributions to the entanglement entropy and Renyi entropies of free bosons and fermions in 3d

    Get PDF
    In the presence of a sharp corner in the boundary of the entanglement region, the entanglement entropy (EE) and Renyi entropies for 3d CFTs have a logarithmic term whose coefficient, the corner function, is scheme-independent. In the limit where the corner becomes smooth, the corner function vanishes quadratically with coefficient σ\sigma for the EE and σn\sigma_n for the Renyi entropies. For a free real scalar and a free Dirac fermion, we evaluate analytically the integral expressions of Casini, Huerta, and Leitao to derive exact results for σ\sigma and σn\sigma_n for all n=2,3,…n=2,3,\dots. The results for σ\sigma agree with a recent universality conjecture of Bueno, Myers, and Witczak-Krempa that σ/CT=π2/24\sigma/C_T = \pi^2/24 in all 3d CFTs, where CTC_T is the central charge. For the Renyi entropies, the ratios σn/CT\sigma_n/C_T do not indicate similar universality. However, in the limit n→∞n \to \infty, the asymptotic values satisfy a simple relationship and equal 1/(4π2)1/(4\pi^2) times the asymptotic values of the free energy of free scalars/fermions on the nn-covered 3-sphere.Comment: 10 pages, 2 figures. v2: typos corrected, references added, asymptotics update
