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…
Dilute limit of a strongly-interacting model of spinless fermions and hardcore bosons on the square lattice
N. G. Zhang, C. L. Henley
In our model, spinless fermions (or hardcore bosons) on a square lattice hop to nearest neighbor sites, and also experience a hard-core repulsion at the nearest neighbor separation…
Classical Mechanics of a Three Spin Cluster
Paul A. Houle, Christopher L. Henley
A cluster of three spins coupled by single-axis anisotropic exchange exhibits classical behaviors ranging from regular motion at low and high energies, to chaotic motion at interme…
Many-Body Density Matrices for Free Fermions
Siew-Ann Cheong, Christopher L. Henley
Building upon an analytical technique introduced by Chung and Peschel [M. Chung and I. Peschel, Phys. Rev. B 64, art. 064412 (2001)], we calculated the density matrix rho_B of a fi…
