The Low-Energy Fixed Points of Random Quantum Spin Chains
E. Westerberg, A. Furusaki, M. Sigrist +1
The one-dimensional isotropic quantum Heisenberg spin systems with random couplings and random spin sizes are investigated using a real-space renormalization group scheme. It is de…
Random Quantum Spin Chains: A Real-Space Renormalization Group Study
E. Westerberg, A. Furusaki, M. Sigrist +1
Quantum Heisenberg spin chains with random couplings and spin sizes are studied using a real-space renormalization group technique. These systems belong to a new universality class…
Anyons on Higher Genus Surfaces - a Constructive Approach
T. H. Hansson, Anders Karlhede, Erik Westerberg
We reconsider the problem of anyons on higher genus surfaces by embedding them in three dimensional space. From a concrete realization based on three dimensional flux tubes bound t…
Quantum Mechanics on Thin Cylinders
Erik Westerberg, T. H. Hansson
We discuss the quantum mechanics of particles of arbitrary statistics on an infinite cylinder with and without a magnetic field perpendicular to the surface. In the presence of a m…
