Published: November 2024

We study systems that approach a state possessing discrete symmetry due to different degenerate realizations for the system. For concreteness, we consider fractionally filled systems where degeneracy comes from the presence of identical sub-lattices. We show that such systems possess a new type of quasiparticles with fractional charges, which we refer to as fractyons. We discuss static and dynamic properties of these quasiparticles.

Photonic axion insulator.

Science

Division of Physics and Applied Physics, School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore, Singapore.

Axions, hypothetical elementary particles that remain undetectable in nature, can arise as quasiparticles in three-dimensional crystals known as axion insulators. Previous implementations of axion insulators have largely been limited to two-dimensional systems, leaving their topological properties in three dimensions unexplored in experiment. Here, we realize an axion insulator in a three-dimensional photonic crystal and probe its topological properties.

Fractional Chern Insulators in Twisted Bilayer MoTe_{2}: A Composite Fermion Perspective.

Phys Rev Lett

The discovery of fractional Chern insulators (FCIs) in twisted bilayer MoTe_{2} has sparked significant interest in fractional topological matter without external magnetic fields. Unlike the flat dispersion of Landau levels, moiré electronic states are influenced by lattice effects within a nanometer-scale superlattice. This Letter examines the impact of these lattice effects on the topological phases in twisted bilayer MoTe_{2}, uncovering a family of FCIs with Abelian anyonic quasiparticles.

Article Synopsis
  • Fractional quantum Hall (FQH) phases involve strong electronic interactions producing anyonic quasiparticles with unique properties, while integer quantum Hall (IQH) effects arise from the band topology of non-interacting electrons.* -
  • Our research reveals unexpected "super-universality" in the critical behavior of FQH and IQH transitions, where both types exhibit the same critical scaling exponent (κ = 0.41 ± 0.02) and localization length exponent (γ = 2.4 ± 0.2).* -
  • Using ultra-high mobility trilayer graphene devices, we demonstrate that these consistent critical exponents can be observed with short-range disorder, unlike previous studies that showed variability in conventional

A recent experiment revealed an unexpected FQHE at filling fraction 3/4 in a GaAs 2D hole system, which contradicts the composite fermion model prediction and the observation of a compressible Hall metal-type state in a twin 2D electron system in GaAs at the same filling fraction 3/4 at almost same other conditions. This finding challenges conventional effective single-quasiparticle model for FQHE exposing its limitations. We explain this experimental observation within a multiparticle approach based on a topological cyclotron commensurability criterion.
