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…
Icosahedral Ti-Zr-Ni: A groundstate quasicrystal?
R. G. Hennig, A. E. Carlsson, K. F. Kelton +1
The first complete ab initio zero-temperature ternary phase diagram is constructed from the calculated energies of the elemental, binary and ternary Ti-Zr-Ni phases; for this, the…
Total-energy-based structure prediction for d(AlNiCo)
Christopher L. Henley, Marek Mihalkovic, Michael Widom
One may predict a quasicrystal structure starting from electrons and quantum mechanics, as approximated by interatomic pair potentials calibrated with ab-initio total-energy calcul…
