Variational Hilbert space truncation approach to quantum Heisenberg antiferromagnets on frustrated clusters
N. A. Modine, Efthimios Kaxiras
We study the spin- Heisenberg antiferromagnet on a series of finite-size clusters with features inspired by the fullerenes. Frustration due to the presence of pentagon…

Adaptive coordinate, real-space electronic structure calculations on parallel computers
Gil Zumbach, N. A. Modine, Efthimios Kaxiras
We present a method for electronic structure calculations that retains all of the advantages of real space and addresses the inherent inefficiency of a regular grid, which has equa…
