Anomalous flux state in higher-order topological superconductors
Yizhi You
We investigate the anomalous flux state of interacting higher-order topological superconductors (HOTSC) protected by rotation symmetries. By introducing a superconducting flux…
Decorated defect condensate, a window to unconventional quantum phase transitions in Weyl semimetals
Yizhi You
We investigate the unconventional quantum phase transitions in Weyl semimetals. The emergent boson fields, coupling with the Weyl fermion bilinears, contain a Wess-Zumino-Witten te…
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…
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…
