Deconfined Metal-Insulator Transitions in Quantum Hall Bilayers
Liujun Zou, Debanjan Chowdhury
We propose that quantum Hall bilayers in the presence of a periodic potential at the scale of the magnetic length can host examples of a Deconfined Metal-Insulator Transition (DMIT…

Deconfined metallic quantum criticality: A gauge-theoretic approach
Liujun Zou, Debanjan Chowdhury
We discuss a new class of quantum phase transitions -- Deconfined Mott Transition (DMT) -- that describe a continuous transition between a Fermi liquid metal with a generic electro…
