Electromagnetic Response of a Half-Filled Chern Band near Topological Criticality
Xinlei Yue, Fabian Pichler, Michael Knap +1
We evaluate electromagnetic-response observables in a half-filled Chern band, across a topological phase transition between a composite Fermi liquid (CFL) and a Fermi liquid (FL) p…
Flux attachment theory of fractional excitonic insulators
Steven Gassner, Ady Stern, C. L. Kane
The search for fractional quantized Hall phases in the absence of a magnetic field has primarily targeted flat-band systems that mimic the features of a Landau level. In an alterna…
Universal charge conductance at Abelian--non-Abelian quantum Hall interfaces
Misha Yutushui, Ady Stern, David F. Mross
Multiple topologically distinct quantum Hall phases can occur at the same Landau level filling factor. It is a major challenge to distinguish between these phases as they only diff…
Compressible quantum liquid with vanishing Drude weight
Ahmed Abouelkomsan, Nisarga Paul, Ady Stern +1
We explore the possibility of quantum liquids that are compressible but have vanishing DC conductivity in the absence of disorder. We show that the composite Fermi liquid emerging…
Transport properties of a half-filled Chern band at the electron and composite fermion phases
Ady Stern, Liang Fu
We consider a half-filled Chern band and its transport properties in two phases that it may form, the electronic Fermi liquid and the composite-fermion Fermi liquid. For weak disor…
