Quantum Hall plateau transitions in disordered superconductors
ArXiv cond-mat/9812155 (1998)
Abstract:
We study a delocalization transition for non-interacting quasiparticles moving in two dimensions, which belongs to a new symmetry class. This symmetry class can be realised in a dirty, gapless superconductor in which time reversal symmetry for orbital motion is broken, but spin rotation symmetry is intact. We find a direct transition between two insulating phases with quantized Hall conductances of zero and two for the conserved quasiparticles. The energy of quasiparticles acts as a relevant, symmetry-breaking field at the critical point, which splits the direct transition into two conventional plateau transitions.Half-filled Landau level as a Fermi liquid of dipolar quasiparticles

Dynamics of self-assembly in complex fluids
NUOVO CIMENTO D 20:12BIS (1998) 2393-2399
Abstract:
Lattice Boltzmann simulations are used to study the phase ordering of a system quenched into a lamellar phase. Hydrodynamic modes are found to be essential for the fluid to avoid frozen metastable configurations and reach the equilibrium state. We also show that a shear imposed on an equilibrium array of droplets can induce a micellar-lamellar transition.Inhomogeneous transport and derivative relations in the quantum Hall regime
