Excitation spectra and ground state properties of the layered spin-1/2 frustrated antiferromagnets Cs_2CuCl_4 and Cs_2CuBr_4
John O. Fjaerestad, Weihong Zheng, Rajiv R. P. Singh +2
We use series expansion methods to study ground- and excited-state properties in the helically ordered phase of spin-1/2 frustrated antiferromagnets on an anisotropic triangular la…
Sensitivity of the interlayer magnetoresistance of layered metals to intralayer anisotropies
Malcolm P. Kennett, Ross H. McKenzie
Many of the most interesting and technologically important electronic materials discovered in the past two decades have two common features: a layered crystal structure and strong…
Quantum dynamics of electronic excitations in biomolecular chromophores: role of the protein environment and solvent
Joel Gilmore, Ross H. McKenzie
We consider continuum dielectric models as minimal models to understand the effect of a surrounding globular protein and solvent on the quantum dynamics of electronic excitations i…
Excitation spectra of the spin-1/2 triangular-lattice Heisenberg antiferromagnet
Weihong Zheng, John O. Fjaerestad, Rajiv R. P. Singh +2
We use series expansion methods to calculate the dispersion relation of the one-magnon excitations for the spin-1/2 triangular-lattice nearest-neighbor Heisenberg antiferromagnet a…
Critical Behaviour of One-particle Spectral Weights in the Transverse Ising Model
C. J. Hamer, J. Oitmaa, Weihong Zheng +1
We investigate the critical behaviour of the spectral weight of a single quasiparticle, one of the key observables in experiment, for the particular case of the transverse Ising mo…
Strong electronic correlations in superconducting organic charge transfer salts
B. J. Powell, Ross H. McKenzie
We review the role of strong electronic correlations in quasi--two-dimensional organic charge transfer salts such as (BEDT-TTF), (BETS) and -[Pd(dmit)]. We b…
