      Bubble generation in a twisted and bent DNA-like model  [Article]

      Larsen, Peter V.; Christiansen, P.L.; Bang, O.; Archilla, Juan F. R.; Gaididei, Yu B. (American Physical Society, 2004)
      The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investigated in two different configurations. ...

      Energy funneling in a bent chain of Morse oscillators with long-range coupling  [Article]

      Larsen, Peter V.; Christiansen, P.L.; Bang, O.; Archilla, Juan F. R.; Gaididei, Yu B. (American Physical Society, 2004)
      A bent chain of coupled Morse oscillators with long-range dispersive interaction is considered. Moving localized excitations may be trapped in the bending region. Thus chain geometry acts like an impurity. An energy ...

      Interplay of nonlinearity and geometry in a DNA-related, Klein-Gordon model with long-range dipole-dipole interaction  [Article]

      Archilla, Juan F. R.; Christiansen, P.L.; Gaididei, Yu B. (American Physical Society, 2001)
      Most of the studies on mathematical models of DNA are limited to next neighbor interaction. However, the coupling between base pairs is thought to be caused by dipole interaction, and, when the DNA strand is bent, the ...

      Moving breathers in a DNA model with competing short and long range dispersive interactions  [Article]

      Cuevas-Maraver, Jesús; Archilla, Juan F. R.; Gaididei, Yu B.; Romero Romero, Francisco (2002)
      Moving breathers is a means of transmitting information in DNA. We study the existence and properties of moving breathers in a DNA model with short range interaction, due to the stacking of the base pairs, and long range ...

      Stationary and moving breathers in a simplified model of curved alpha--helix proteins  [Article]

      Archilla, Juan F. R.; Gaididei, Yu B.; Christiansen, P.L.; Cuevas-Maraver, Jesús (2002)
      The existence, stability and movability of breathers in a model for alpha-helix proteins is studied. This model basically consists a chain of dipole moments parallel to it. The existence of localized linear modes brings ...
