dc.description.abstract | 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 interaction, due
to the finite dipole moment of the bond within each base pair.
In our study, we have found that mobile breathers exist for a wide range of
the parameter values, and the mobility of these breathers is hindered by the long
range interaction. This fact is manifested by: (a) an increase of the effective mass
of the breather with the dipole–dipole coupling parameter; (b) a poor quality of
the movement when the dipole–dipole interaction increases; and (c) the existence
of a threshold value of the dipole–dipole coupling above which the breather is not
movable.
An analytical formula for the boundaries of the regions where breathers are movable
is calculated. Concretely, for each value of the breather frequency, it can be
obtained the maximum value of the dipole–dipole coupling parameter and the maximum
and minimum values of the stacking coupling parameter where breathers are
movable. Numerical simulations show that, although the necessary conditions for
the mobility are fulfilled, breathers are not always movable.
Finally, the value of the dipole–dipole coupling constant is obtained through quantum
chemical calculations. They show that the value of the coupling constant is
small enough to allow a good mobility of breathers. | es |
