Noncommutative Geometry and Deformation Quantization in the Quantum Hall Fluids with Inhomogeneous Magnetic Fields
arXiv:2304.04002 · doi:10.1088/1751-8121/ad018b
Abstract
It is well known that noncommutative geometry naturally emerges in the quantum Hall states due to the presence of strong and constant magnetic fields. Here, we discuss the underlying noncommutative geometry of quantum Hall fluids in which the magnetic fields are spatially inhomogenoeus. We analyze these cases by employing symplectic geometry and Fedosov's deformation quantization, which rely on symplectic connections and Fedosov star-product. Through this formalism, we unveil some new features concerning the static limit of the Haldane's unimodular metric and the Girvin-MacDonald-Platzman algebra of the density operators, which plays a central role in the fractional quantum Hall effect.
