Mixed state concurrence for symmetric systems
S. H. Curnoe, D. Gajera, C. Wei
We present a method to quantify entanglement in mixed states of highly symmetric systems. Symmetry constrains interactions between parts and predicts the degeneracies of the states…

Concurrence and entanglement on a 16-site spin-1/2 pyrochlore cluster
C. Wei, S. H. Curnoe
We examine the entanglement of the ground state of a 16-site spin-1/2 pyrochlore cluster in the quantum spin ice regime via various calculations of -concurrence. Exact gr…
