Abstract

The ground state of a double-layer fractional quantum Hall system of spin- 1 2 electrons is obtained numerically for finite systems for various values of the total Landau level filling v, as a function of the layer separation d. The inclusion of spin degrees of freedom is shown to give rise to versatile ground states, where the total spin and the inter-layer correlation are linked and change sensitively with v and d. A typical example is an Stot=0 ground state for v= 4 7 having a large overlap with the ψ3,2,1 trial function, which has no counterpart in single-layer systems.
