      Charge transport in a nonlinear, three-dimensional DNA model with disorder  [Presentation]

      Archilla, Juan F. R.; Hennig, Dirk; Agarwal, J. (WorldScientific, 2003)
      We study the transport of charge due to polarons in a model of DNA which takes in account its 3D structure and the coupling of the electron wave function with the H–bond distortions and the twist motions of the base ...

      Charge transport in poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers  [Article]

      Hennig, Dirk; Starikov, Eugen B.; Archilla, Juan F. R.; Palmero Acebedo, Faustino (Springer, 2003)
      We investigate the charge transport in synthetic DNA polymers built up from single types of base pairs. In the context of a polaron-like model, for which an electronic tight-binding system and bond vibrations of the double ...

      Localization Properties of Electronic States in Polaron Model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers  [Article]

      Yamada, Hiroaki; Starikov, Eugen B.; Hennig, Dirk; Archilla, Juan F. R. (Societá Italiana di Fisica, 2005)
      We numerically investigate localization properties of electronic states in a static model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers with realistic parameters obtained by quantum-chemical calculation. The ...

      Modeling the thermal evolution of enzyme-created bubbles in DNA  [Article]

      Hennig, Dirk; Archilla, Juan F. R.; Romero, J.M. (Royal Society, 2005)
      The formation of bubbles in nucleic acids (NAs) is fundamental in many biological processes such as DNA replication, recombination, telomere formation and nucleotide excision repair, as well as RNA transcription and ...

      Moving breathers in bent DNA with realistic parameters  [Article]

      Cuevas-Maraver, Jesús; Starikov, Evgeni B.; Archilla, Juan F. R.; Hennig, Dirk (2004-10-30)
      Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen ...

      Multi-site H-bridge breathers in a DNA–shaped double strand  [Article]

      Hennig, Dirk; Archilla, Juan F. R. (IOP Publishing, 2004)
      We investigate the formation process of nonlinear vibrational modes representing broad H-bridge multi–site breathers in a DNA–shaped double strand. Within a network model of the double helix we take individual motions ...

      Nonlinear charge transport mechanism in periodic and disordered DNA  [Article]

      Hennig, Dirk; Archilla, Juan F. R.; Agarwal, J. (Elsevier, 2003)
      We study a model for polaron-like charge transportmechanism along DNA molecules with emphasis on the impact of parametrical and structural disorder. Our model Hamiltonian takes into account the coupling of the charge ...

      Polaronic charge transport mechanism in DNA  [Chapter of Book]

      Hennig, Dirk; Archilla, Juan F. R. (Elsevier, 2006)
      For the detailed understanding of the conduction mechanism in DNA we use models based on the concept of polaron and breather solutions. We describe how charge transport relies on the coupling of the charge carrying unit ...

      Stretching and relaxation dynamics in double stranded DNA  [Article]

      Hennig, Dirk; Archilla, Juan F. R. (Elsevier, 2004)
      We study numerically the mechanical stability and elasticity properties of duplex DNA molecules within the frame of a network model incorpo- rating microscopic degrees of freedom related with the arrangement of the base ...
