Effect of disorder on quantum phase transitions in anisotropic XY spin chains in a transverse field
J. E. Bunder, Ross H. McKenzie
We present some exact results for the effect of disorder on the critical properties of an anisotropic XY spin chain in a transverse field. The continuum limit of the corresponding…
Phase diagram for a class of spin-half Heisenberg models interpolating between the square-lattice, the triangular-lattice and the linear chain limits
Zheng Weihong, Ross H. McKenzie, Rajiv R. P Singh
We study the spin-half Heisenberg models on an anisotropic two-dimensional lattice which interpolates between the square-lattice at one end, a set of decoupled spin-chains on the o…
The Heisenberg antiferromagnet on an anisotropic triangular lattice: linear spin-wave theory
J. Merino, Ross H. McKenzie, J. B. Marston +1
We consider the effect of quantum spin fluctuations on the ground state properties of the Heisenberg antiferromagnet on an anisotropic triangular lattice using linear spin-wave the…
Phase diagram of a Heisenberg spin-Peierls model with quantum phonons
Robert J. Bursill, Ross H. McKenzie, Chris J. Hamer
Using a new version of the density-matrix renormalization group we determine the phase diagram of a model of an antiferromagnetic Heisenberg spin chain where the spins interact wit…
Comparison of coherent and weakly incoherent transport models for the interlayer magnetoresistance of layered Fermi liquids
Perez Moses, Ross H. McKenzie
The interlayer magnetoresistance of layered metals in a tilted magnetic field is calculated for two distinct models for the interlayer transport. The first model involves coherent…
Incoherent interlayer transport and angular-dependent magnetoresistance oscillations in layered metals
Ross H. McKenzie, Perez Moses
The effect of incoherent interlayer transport on the interlayer resistance of a layered metal is considered. We find that for both quasi-one-dimensional and quasi-two-dimensional F…
