Critical Majorana Fermion at a Topological Quantum Hall Bilayer Transition

Author(s): Cristian Voinea, Wei Zhu, Nicolas Regnault, and Zlatko Papić Quantum Hall bilayers are a uniquely tunable platform that can realize continuous transitions between distinct topological phases of matter. One prominent example is the transition between the Halperin state and the Moore-Read Pfaffian, long predicted to host a critical theory of Majorana fermions b… [Phys. Rev.
