Abstract
In this paper, we examine interwell tunneling between a pair of fractional quantum Hall liquids in a double-quantum-well system in a tilted magnetic field. Using a variational Monte Carlo method, we calculate moments of the intra-Landau-level tunneling spectrum as a function of in-plane field component ∥and interwell spacing d. This is done for a variety of incompressible states including a pair of ν=1/3 layers ([330]), a pair of ν=1/5 layers ([550]), and Halperin’s [331] state. The results suggest a technique to extract interwell correlations from the tunneling spectral data.
