Entanglement scaling and charge fluctuations in a Fermi liquid of composite fermions
Cristian Voinea, Songyang Pu, Ajit C. Balram +1
The composite fermion Fermi liquid (CFL) state at filling of a Landau level is a paradigmatic non-Fermi liquid borne out purely by Coulomb interactions. But in what ways is…
Topologically protected emergent Fermi surface in an Abrikosov vortex lattice
Songyang Pu, Jay D. Sau, Rui-Xing Zhang
We show that a three-dimensional (3D) fully gapped type-II superconductor can feature emergent in-gap Fermi surfaces of Caroli-de Gennes Matricon (CdGM) quasiparticles in the prese…
Microscopic Model for Fractional Quantum Hall Nematics
Songyang Pu, Ajit C. Balram, Joseph Taylor +2
Geometric fluctuations of the density mode in a fractional quantum Hall (FQH) state can give rise to a nematic FQH phase, a topological state with a spontaneously broken rotational…
