Pairing and condensation of Laughlin quasiparticles in fractional quantum Hall systems

Abstract

From the analysis of their interaction pseudopotentials, it is argued that (at certain filling factors) Laughlin quasiparticles can form pairs. It is further proposed that such pairs could have Laughlin correlations with one another and form condensed states of a new type. The sequence of fractions corresponding to these states includes all new fractions observed recently in experiment (e.g., ν=5/13, 3/8, or 4/11).
