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…
Symmetry considerations in exact diagonalization: spin-1/2 pyrochlore magnets
C. Wei, S. H. Curnoe
We describe how the methods of group theory (symmetry) are used to optimize the problem of exact diagonalization of a quantum system on a 16-site pyrochlore lattice. By analyticall…
Exact diagonalization for spin-1/2 spin ice pyrochlores
C. Wei, S. H. Curnoe
We find exact solutions to the Hamiltonian of a 16-site spin-1/2 pyrochlore crystal with nearest neighbour exchange interactions. The methods of group theory (symmetry) are used to…
A general model of MnSi-like spiral magnets
K. P. W. Hall, S. H. Curnoe
A general, symmetry-allowed model of nearest-neighbour interactions for MnSi-like magnets is presented. A left-handed helical magnet phase occurs within a large parameter space of…
Analytic description of spin waves in dipolar/octupolar pyrochlore magnets
I. A. Assi, S. H. Curnoe
We derive analytic forms for spin waves in pyrochlore magnets with dipolar-octupolar interactions, such as . We obtain full knowledge of the diagonal…
