Theory of Nematic Fractional Quantum Hall State
Yizhi You, Gil Young Cho, Eduardo Fradkin
We derive an effective field theory for the isotropic-nematic quantum phase transition of fractional quantum Hall (FQH) states. We demonstrate that for a system with an isotropic b…
Framing Anomaly in the Effective Theory of Fractional Quantum Hall Effect
Andrey Gromov, Gil Young Cho, Yizhi You +2
We consider the geometric part of the effective action for Fractional Quantum Hall Effect (FQHE). It is shown that accounting for the framing anomaly of the quantum Chern-Simons th…
Condensation of Lattice Defects and Melting Transitions in Quantum Hall phases
Gil Young Cho, Onkar Parrikar, Yizhi You +2
Motivated by recent progress in understanding the interplay between lattice and electronic topological phases, we consider quantum-melting transitions of {\it weak} quantum liquid…
Topological Pair-Density-Wave Superconducting States
Gil Young Cho, Rodrigo Soto-Garrido, Eduardo Fradkin
We show that the pair-density-wave (PDW) superconducting state emergent in extended Heisenberg-Hubbard models in two-leg ladders is topological in the presence of an Ising spin sym…
Geometry of Fractional Quantum Hall Fluids
Gil Young Cho, Yizhi You, Eduardo Fradkin
We use the field theory description of the fractional quantum Hall states to derive the universal response of these topological fluids to shear deformations and curvature of their…
Symmetry-protected Topological Phases, Generalized Laughlin Argument and Orientifolds
Chang-Tse Hsieh, Olabode Mayodele Sule, Gil Young Cho +2
We generalize Laughlin's flux insertion argument, originally discussed in the context of the quantum Hall effect, to topological phases protected by non-on-site unitary symmetries,…
