Anharmonic Ground state selection in the pyrochlore antiferromagnet
Uzi Hizi, Christopher L. Henley
In the pyrochlore lattice Heisenberg antiferromagnet, for large spin length , the massive classical ground state degeneracy is partly lifted by the zero-point energy of quantum…
Effective Hamiltonians for large-S pyrochlore antiferromagnet
Uzi Hizi, Christopher L. Henley
The pyrochlore lattice Heisenberg antiferromagnet has a massive classical ground state degeneracy. We summarize three approximation schemes, valid for large spin length , to cap…
Effective Hamiltonian for the Pyrochlore antiferromagnet: semiclassical derivation and degeneracy
U. Hizi, C. L. Henley
In the classical pyrochlore lattice Heisenberg antiferromagnet, there is a macroscopic continuous ground state degeneracy. We study semiclassical limit of large spin length , ke…
Semiclassical ordering in the large-N pyrochlore antiferromagnet
U. Hizi, Prashant Sharma, C. L. Henley
We study the semiclassical limit of the generalization of the pyrochlore lattice Heisenberg antiferromagnet by expanding about the saddlepoint in powers of a…
Hole on a stripe in a spinless fermion model
U. Hizi, C. L. Henley
In the spinless fermion model on a square lattice with infinite nearest-neighbor repulsion, holes doped into the half-filled ordered state form stripes which, at low doping, are st…
