Corner contributions to holographic entanglement entropy in non-conformal backgrounds
We study corner contributions to holographic entanglement entropy in
non-conformal backgrounds: a kink for D2-branes as well as a cone and two
different types of crease for D4-branes. Unlike 2+1-dimensional CFTs, the
corner contribution to the holographic entanglement entropy of D2-branes
exhibits a power law behaviour rather than a logarithmic term. However, the
logarithmic term emerges in the holographic entanglement entropy of D4-branes.
We identify the logarithmic term for a cone in D4-brane background as the
universal contribution under appropriate limits and compare it with other
physical quantities.Comment: 25 pages, 1 figure, discussions in section 5.2 improved, typos
