L. Brizhik et al., Delayed luminescence of biological systems arising from correlated many-soliton states - art. no. 031902, PHYS REV E, 6403(3), 2001, pp. 1902
The kinetics of the delayed luminescence arising from correlated coherent m
any-soliton states in low-dimensional macromolecular systems, is calculated
and shown to be different from the one arising from independent soliton st
ates. The correlation between coherent electron states is essential at rela
tively high levels of excitation in the presence of very long macromolecule
s in a system. These conditions can be fulfilled in such biological systems
. like algae Acetabularia Acetabulum. The cytoskeleton of this unicellular
alga contains macromolecular structures (actin filaments, microtubules, etc
.) of the length of several hundreds angstroms and more, in which many-soli
ton coherent states can exist. Indeed, the correlated coherent model is sho
wn to give better fit of the experimental data for this type of algae in a
wide range of intensities of the stimulating light, as compared with the mo
del of noncorrelated solitons. The nonlinearity of the dependence of delaye
d luminescence intensity on the level of excitation increases with the incr
ease of correlation between solitons.
