Fractional quantum Hall effect in optical lattices

Frontiers in Physics, 2023
In this research, we study the bosonic fractional quantum Hall (FQH) states in a system of ultracold bosons in a two-dimensional optical lattice in the presence of a synthetic magnetic field, described by the bosonic Harper–Hofstadter Hamiltonian. We use

Observation of Integer and Fractional Quantum Anomalous Hall Effects in Twisted Bilayer MoTe_{2}

Physical Review X, 2023
The interplay between strong correlations and topology can lead to the emergence of intriguing quantum states of matter. One well-known example is the fractional quantum Hall effect, where exotic electron fluids with fractionally charged excitations form

Andreev reflection of fractional quantum Hall quasiparticles

Nature Communications, 2021
Andreev reflection is normally known to occur at a metal-superconductor interface. Here, Hashisaka et al. observe an Andreev-like process in a narrow junction between fractional and integer quantum Hall states originating from a topological quantum many ...

The Fractional Quantum Hall Effect

Reviews of Modern Physics, 1999
Two-dimensional electron systems in a high magnetic field behave very strangely. They exhibit rational fractional quantum numbers and contain exactly fractionally charged particles. Electrons seem to absorb magnetic flux quanta, altering their statistics and consuming the magnetic field. They condense into a manifold of novel ground states of boson and

Anyons and fractional quantum Hall effect in fractal dimensions

Physical Review Research, 2020
The fractional quantum Hall effect is a paradigm of topological order and has been studied thoroughly in two dimensions. Here, we construct a different type of fractional quantum Hall system, which has the special property that it lives in fractal ...

Universal Periods in Quantum Hall Droplets [PDF]

, 2007
Using the hierarchy picture of the fractional quantum Hall effect, we study the ground-state periodicity of a finite size quantum Hall droplet in a quantum Hall fluid of a different filling factor.

Fractional quantum Hall effect for extended objects: from skyrmionic membranes to dyonic strings

Journal of High Energy Physics, 2022
It is well known that in two spatial dimensions the fractional quantum Hall effect (FQHE) deals with point-like anyons that carry fractional electric charge and statistics. Moreover, in presence of a SO(3) order parameter, point-like skyrmions emerge and
