Polarized multiple scattering
The theory of polarization in multiple scattering is very similar
to the theory of writhe in semiflexible polymers, such as DNA:

 Berry Phases and
multiple scattering

Flowerlike figure from observation of polarized light in
strongly scattering sample. Fourfold symmetry from the Berry phase
of \(4 \pi\) in backscattering geometry.


Writhe geometry
Formulations of the writhe based on the local torsion, \(\tau\) can
not be used in polymer physics, one must use more global
considerations to understand the geometry

 Geometry of
writhe


A bent beam with writhe leads to rotation.

Writhe is only defined modulo \( 4 \pi \) in open
geometries


Semiflexible polymers
Anisotropic dynamics in semiflexible polymers leads to a mixture of
transverse dynamics in \( t^{3/4} \) and longitudinal dynamics in
\( t^{7/8} \).

effects in microrheology
 Actin filaments have a persistence
length of \(10\mu\), this is much stiffer than most polymers. How
does this affect the rheology and mechanics of semidiluate
solutions? The modulus is given by \(G= \frac{kT}{\ell_e}\) where
the collision length in the tube \(\ell_e\) is close to a micron.
Uncrosslinked actin is thus rather soft.
