Twisted van der Waals Josephson junction based on high-Tc superconductor
Jongyun Lee, Wonjun Lee, Gi-Yeop Kim +8
Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layere…
Topological Phases Protected By Reflection Symmetry and Cross-cap States
Gil Young Cho, Chang-Tse Hsieh, Takahiro Morimoto +1
Twisting symmetries provides an efficient method to diagnose symmetry-protected topological (SPT) phases. In this paper, edge theories of (2+1)-dimensional topological phases prote…
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…
