Tunneling Between a Pair of Parallel Hall Droplets

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 $B_{\parallel }$ and interwell spacing $d$. This is done for variety of incompressible states including a pair of $\nu =1/3$ layers ([330]), pair of $\nu =1/5$ layers ([550]), and Halperin's [331] state. The results suggest a technique to extract interwell correlations from the tunneling spectral data.
