Abstract
We study the short-range correlations in a double-quantum-wire structu re within the self-consistent scheme of Singwi el al. [Phys. Rev. 179, 589 (1968)]. The local-field factors and static correlation functions are calculated for electron and electron-hole double-wire systems. Th e ground-state energy and collective excitations are discussed. It is found that the interwire correlations become quite important for elect ron-hole systems.
