Composite fermions in ideal Chern bands

Songyang Pu, Liangtao Peng, Shaffique Adam

The composite-fermion framework maps the strongly correlated fractional quantum Hall state onto a weakly interacting integer quantum Hall state in a reduced effective magnetic fiel…

Local spectroscopy of anyons bound to charge traps

Jeong Min Park, Cristian Voinea, Yen-Chen Tsui +7

Fractional quantum Hall states host anyons, emergent quasiparticles with fractional charge and nontrivial exchange statistics. Controlling, trapping, and braiding anyons are centra…

Photonic antiferromagnetic topological insulator with a single surface Dirac cone

Fujia Chen, Ning Han, Songyang Pu +12

Antiferromagnetism, characterized by magnetic moments aligned in alternating directions with a vanished ensemble average, has garnered renewed interest for its potential applicatio…

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…

Fingerprints of Composite Fermion Lambda Levels in Scanning Tunneling Microscopy

Songyang Pu, Ajit C. Balram, Yuwen Hu +6

Composite fermion (CF) is a topological quasiparticle that emerges from a non-perturbative attachment of vortices to electrons in strongly correlated two-dimensional materials. Sim…

Deformed Fredkin model for the Moore-Read state on thin cylinders

Cristian Voinea, Songyang Pu, Ammar Kirmani +3

We propose a frustration-free model for the Moore-Read quantum Hall state on sufficiently thin cylinders with circumferences magnetic lengths. While the Moore-Read Ham…
