  We investigate the correlations of mutual positions of charge density waves
nodes in side-by-side placed InAs nanowires in presence of a conductive atomic
force microscope tip served as a mobile gate at helium temperatures. Scanning
gate microscopy scans demonstrate mutual correlation of positions of charge
density waves nodes of two wires. A general mutual shift of the nodes positions
and "crystal lattice mismatch" defect were observed. These observations
demonstrate the crucial role of Coulomb interaction in formation of charge
density waves in InAs nanowires.
