# Microscopic theory of fractional excitations in gapless quantum Hall states: semi-quantized quantum Hall states

@article{Turker2019MicroscopicTO, title={Microscopic theory of fractional excitations in gapless quantum Hall states: semi-quantized quantum Hall states}, author={Ouguz Turker and Tobias Meng}, journal={SciPost Physics}, year={2019} }

We derive the low-energy theory of semi-quantized quantum Hall
states, a recently observed class of gapless bilayer fractional quantum
Hall states. Our theory shows these states to feature gapless
quasiparticles of fractional charge coupled to an emergent Chern-Simons
gauge field. These gapless quasiparticles can be understood as
composites of electrons and Laughlin-like quasiparticles. We show that
semi-quantized quantum Hall states exhibit perfect interlayer drag, host
non-Fermi liquid…
