Universal divergence of the Renyi entropy of a thinly sliced torus at the Ising fixed point
Bohdan Kulchytskyy, Lauren E. Hayward Sierens, Roger G. Melko
The entanglement entropy of a quantum critical system can provide new universal numbers that depend on the geometry of the entangling bipartition. We calculate a universal number c…

Probing trihedral corner entanglement for Dirac fermions
Grigory Bednik, Lauren E. Hayward Sierens, Minyong Guo +2
We investigate the universal information contained in the Renyi entanglement entropies for a free massless Dirac fermion in three spatial dimensions. Using numerical calculations o…
