Structure of Periodic Crystals and Quasicrystals in Ultrathin Film Ba-Ti-O
Eric Cockayne, Marek Mihalkovic, Christopher L. Henley
We model the remarkable thin-film Ba-Ti-O structures formed by heat treatment of an initial perovskite BaTiO thin film on a Pt(111) surface. All structures contain a rumpled Ti…
Schwinger boson mean field perspective on emergent spins in diluted Heisenberg antiferromagnets
Shivam Ghosh, Hitesh J. Changlani, Christopher L. Henley
Using an adaptation of Schwinger boson mean field theory (SBMFT) for nonuniform systems, we study the nature of low-energy spin excitations on the square and Bethe lattice at their…
Density-matrix based numerical methods for discovering order and correlations in interacting systems
Christopher L. Henley, Hitesh J. Changlani
We review recently introduced numerical methods for the unbiased detection of the order parameter and/or dominant correlations, in many-body interacting systems, by using reduced d…
Phase diagram of the Kondo lattice model on the Kagome lattice
Shivam Ghosh, Patrick O' Brien, Christopher L. Henley +1
We consider the potential for novel forms of magnetism arising from the subtle interplay between electrons and spins in the under-screened kagome Kondo lattice model. At weak coupl…
Semi-classical spin dynamics of the antiferromagnetic Heisenberg model on the kagome lattice
Mathieu Taillefumier, Julien Robert, Christopher L. Henley +2
We investigate the dynamical properties of the classical antiferromagnetic Heisenberg model on the kagome lattice using a combination of Monte Carlo and molecular dynamics simulati…
Orientational interaction and ordering of Cd_4 tetrahedra in a quasicrystal approximant
Woosong Choi, Christopher L. Henley, Marek Mihalkovic
We model the quasicrystal-related structure CaCd, a bcc packing of icosahedral clusters containing tetrahedra which undergo orientational orderings at T<100 K. We use general s…
