Three-dimensional disordered conductors in a strong magnetic field: surface states and quantum Hall plateaus

ArXiv cond-mat/9510164 (1995)

Authors:

JT Chalker, A Dohmen

Abstract:

We study localization in layered, three-dimensional conductors in strong magnetic fields. We demonstrate the existence of three phases - insulator, metal and quantized Hall conductor - in the two-dimensional parameter space obtained by varying the Fermi energy and the interlayer coupling strength. Transport in the quantized Hall conductor occurs via extended surface states. These surface states constitute a subsystem at a novel critical point, which we describe using a new, directed network model.

Fluctuation-Induced Interactions between Rods on Membranes and Interfaces

ArXiv cond-mat/9509071 (1995)

Authors:

R Golestanian, M Goulian, M Kardar

Abstract:

We consider the interaction between two rods embedded in a fluctuating surface which is governed by either surface tension or rigidity. The modification of fluctuations by the rods leads to an attractive long-range interaction that falls off as $1/R^4$ with their separation. The orientational dependence of the resulting interaction is non-trivial and may lead to interesting patterns of rod-like objects on such surfaces.
