TUNNELING BETWEEN A PAIR OF PARALLEL HALL DROPLETS

In this paper, we examine interwell tunneling between a pair of fracti onal quantum Hall liquids in a double-quantum-well system in a tilted magnetic field. Using a variational Monte Carlo method, we calculate m oments of the intra-landau-level tunneling spectrum as a function of i n-plane field component B-parallel to and interwell spacing d. This is done for a variety of incompressible states including a pair of v=1/3 layers ([330]), a pair of v=1/5 layers ([550]), and Halperin's [331] state. The results suggest a technique to extract interwell correlatio ns from the tunneling spectral data.
