Phys. Rev. Lett. 95, 126601 (2005) [4 pages]Sequencing-Independent Delocalization in a DNA-Like Double Chain with Base PairingReceived 9 September 2004; published 14 September 2005 The question of whether or not DNA is intrinsically conducting 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 in opposition to correlations along each chain. We show that a disordered base paired double chain presents truly or, at least, effectively delocalized states. This effect is irrespective to the sequencing along each chain. © 2005 The American Physical Society URL:
