Emergence: from physics to biology, sociology, and computer science
Ross H. McKenzie
Many systems involve numerous interacting parts and the whole system can have properties that the individual parts do not. I take this novelty as the defining characteristic of an…
Quantum Monte Carlo study of the one-dimensional Holstein model of spinless fermions
Ross H. McKenzie, C. J. Hamer, D. W. Murray
The Holstein model of spinless fermions interacting with dispersionless phonons in one dimension is studied by a Green's function Monte Carlo technique. The ground state energy, fi…
Microscopic theory of the pseudogap and Peierls transition in quasi-one-dimensional materials
Ross H. McKenzie
The problem of deriving from microscopic theory a Ginzburg-Landau free energy functional to describe the Peierls or charge-density-wave transition in quasi-one-dimensional material…
Ginzburg-Landau theory of phase transitions in quasi-one-dimensional systems
Ross H. McKenzie
A wide range of quasi-one-dimensional materials, consisting of weakly coupled chains, undergo three-dimensional phase transitions that can be described by a complex order parameter…
