Electrodynamics of coupled charge-density wave 2D electron gas systems

Original · EN

The combined inductive and coulombic coupling of an orbitally quantized two-dimensional electron gas to a one-dimensional charge-density wave (CDW) is shown to give rise to an anisotropic quantum fluid in which the Hall electric field, current and gradient of the CDW phase are all exponentially screened from within the bulk. The characteristic penetration depth is similar to the London penetration depth of relevance to superconductivity.
