Magnetic screening properties of an incompressible chiral fluid

TL;DR

This paper investigates how a static magnetic field penetrates an idealized layered chiral quantum fluid, revealing an orientation-dependent screening effect that is intermediate between superconducting and non-superconducting behaviors.

Contribution

It introduces a model for magnetic screening in an incompressible chiral quantum fluid, highlighting orientation-dependent effects not previously characterized.

Findings

Magnetic field screening depends on orientation relative to layers.

The system exhibits behavior between superconducting and non-superconducting fluids.

Screening effectiveness varies with magnetic field direction.

Abstract

We study the possible penetration of a static magnetic field in an idealized sample of many layers supporting a two dimensional charged chiral quantum fluid, to see whether there is a kind of Meissner effect. This is a non standard problem since the quantum fluid is incompressible having a gap in its spectrum. We find that the system shows an intermediate behaviour between superconducting and non-superconducting fluids, the magnetic field being screened or not depending on its orientation relative to the layers.
