Phason Disorder Effects in the Penrose Tiling Antiferromagnet
Attila Szallas, Anuradha Jagannathan
We discuss the ground state of a disordered two dimensional Heisenberg antiferromagnet. The starting structure is taken to be a perfectly deterministic quasiperiodic tiling, and th…

Antiferromagnetism in two-dimensional quasicrystals
Anuradha Jagannathan, Attila Szallas
Quasiperiodic structures possess long range positional order, but are freed of constraints imposed by translational invariance. For spins interacting via Heisenberg couplings, one…

Spin waves and local magnetizations on the Penrose tiling
Attila Szallas, Anuradha Jagannathan
We consider a Heisenberg antiferromagnet on the Penrose tiling, a quasiperiodic system having an inhomogeneous Neel-ordered ground state. Spin wave energies and wavefunctions are s…
