*Long-range interactions between membrane inclusions: Electric field
induced giant amplification of the pairwise potential*
The aim of this work is to revisit the phenomenological theory of the
interaction between membrane inclusions, mediated by the membrane
fluctuations. We consider the case where the inclusions are separated by
distances larger than their characteristic size. Within our macroscopic
approach a physical nature of such inclusions is not essential. However,
we have always in mind two prototypes of such inclusions: proteins and
RNA macromolecules. Because the interaction is driven by the membrane
fluctuations and the coupling between inclusions and the membrane, it is
possible to change the interaction potential by external actions
affecting these factors. As an example of such external action we
consider an electric field. Under external electric field (both dc or
ac), we propose a new coupling mechanism between inclusions possessing
dipole moments (as it is the case for most protein macromolecules) and
the membrane. We found, quite unexpected and presumably for the first
time, that the new coupling mechanism yields to giant enhancement of the
pairwise potential of the inclusions. This result opens up a way to
handle purposefully the interaction energy, and as well to test of the
theory set forth in our article.
Results are published in Annals of Physics 447(Pt.2), 168916 (2022)
