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

We study the effect of dynamical screening of interactions on the transition temperatures (T_{c}) of exciton condensation in a symmetric bilayer of quadratically dispersing electrons and holes by solving the linearized Eliashberg equations for the anomalous interlayer Green's functions. We find that T_{c} is finite for the range of density and layer separations studied, decaying exponentially with interlayer separation. T_{c} is suppressed well below that predicted by a Hartree Fock mean field theory with unscreened Coulomb interaction, but is above the estimates from the statically screened Coulomb interaction.

Peripheral artery disease is a prevalent illness affecting more than 200 million people worldwide. A commonly used technique to manage the condition has been open endarterectomy. However, in recent times, a shift towards minimally invasive techniques has resulted in endovascular intervention as a popular alternative.

The interplay between interaction and disorder-induced localization is of fundamental interest. This article addresses localization physics in the fractional quantum Hall state, where both interaction and disorder have nonperturbative consequences. We provide compelling theoretical evidence that the localization of a single quasiparticle of the fractional quantum Hall state at filling factor ν=n/(2n+1) has a striking quantitative correspondence to the localization of a single electron in the (n+1)th Landau level.
