Metallic Nature of the Four-Dimensional Quantum Hall Edge
Y. D. Chong, R. B. Laughlin
We study the density response of the four-dimensional quantum Hall fluid found by Zhang and Hu, which has been advanced as a model of emergent relativity. We calculate the density-…

Evidence for composite nature of quasiparticles in the 2D t-J model
P. Beran, D. Poilblanc, R. B. Laughlin
It is shown that the dynamics of a single hole in a quantum antiferromagnet (described by the t--J model) can be simply understood in terms of a composite quasiparticle. This descr…
