Cubic trihedral corner entanglement for a free scalar
Lauren E. Hayward Sierens, Pablo Bueno, Rajiv R. P. Singh +2
We calculate the universal contribution to the -Renyi entropy from a cubic trihedral corner in the boundary of the entangling region in 3+1 dimensions for a massless free scalar…

Bounds on corner entanglement in quantum critical states
Pablo Bueno, William Witczak-Krempa
The entanglement entropy in many gapless quantum systems receives a contribution from corners in the entangling surface in 2+1d. It is characterized by a universal function …
