Phys. Rev. Lett. 85, 5408–5411 (2000)Fractional Quantum Hall Effect in Infinite-Layer SystemsReceived 6 July 2000; published in the issue dated 18 December 2000 Stacked two dimensional electron systems in transverse magnetic fields exhibit three dimensional fractional quantum Hall phases. We analyze the simplest such phases and find novel bulk properties, e.g., irrational braiding. These phases host “one and a half” dimensional surface phases in which motion in one direction is chiral. We offer a general analysis of conduction in the latter by combining sum rule and renormalization group arguments, and find that when interlayer tunneling is marginal or irrelevant they are chiral semimetals that conduct only at T>0 or with disorder. © 2000 The American Physical Society URL:
