摘要：
We study the edge transport properties of paired fractional quantum Hall (FQH) states - the Haldane-Rezayi (HR), Moore-Read (Pfaffian) and Halperin (3 3 1) states. The table of exponents is given for the tunneling between the edges of paired FQH states in gated 2D structures and the tunneling into the edge of FQH states from a normal Fermi liquid (N). It is found that HR, Pfaffian and 3 3 1 states have different exponents for quasiparticle tunneling. For the tunneling through a FQH-N junction, we propose unusual Andreev reflection processes that may also probe the nonabelian FQH states. (C) 1998 Elsevier Science Ltd. All rights reserved.
