Double chains with base pairing: delocalization irrespective to DNA sequencing

The question of whether DNA is intrinsically conducting or not is still a challenge. The ongoing debate on DNA molecules as an electronic material has so far underestimated a key distinction of the system: the role of base pairing (inter chain correlation) in opposition to correlations along each chain. In the present work we show that a disordered double-chain presents truly delocalized states. This effect is irrespective to the sequencing along each chain: DNA-like base pairing reveals to be an efficient delocalization mechanism.
