The phenomenon of fractional quantum Hall effect (FQHE) was first experimentally observed
33 years ago. FQHE involves strong Coulomb interactions and correlations among the …

The quantum dynamics of the intrinsic metric profoundly influence the neutral excitations in
the fractional quantum Hall system, as established by Haldane [Phys. Rev. Lett. 107, 116801 …

We construct model wave functions for the collective modes of fractional quantum Hall
systems. The wave functions are expressed in terms of symmetric polynomials characterized …

Some models of the 5/2 fractional quantum Hall state predict that the quasiparticles, which
carry the charge, have non-Abelian statistics: exchange of two quasiparticles changes the …

The Moore-Read state, one of the leading candidates for describing the fractional quantum
Hall effect at filling factor ν= 5/2, is a paradigmatic p-wave superconductor with non-Abelian …

The topological p-wave pairing of composite fermions, believed to be responsible for the 5/2
fractional quantum Hall effect (FQHE), has generated much exciting physics. Motivated by …

We measure weak quasiparticle tunneling across a constriction in the second Landau level.
At ν= 7/3, 8/3, and 5/2, comparison of temperature and dc bias dependence to weak …

We introduce different types of quenches to probe the nonequilibrium dynamics and multiple
collective modes of bilayer fractional quantum Hall states. We show that applying an electric …

Abstract The paradigmatic Migdal–Eliashberg theory of the electron–phonon problem is
central to the understanding of superconductivity in conventional metals. This powerful …

We introduce a quench of the geometry of Landau level orbitals as a probe of
nonequilibrium dynamics of fractional quantum Hall (FQH) states. We show that such …
