Multi-scale Monte Carlo algorithm for Lennard-Jones fluids
Introduce a collective update in a fluid which moves many particles
simultaneously. It leads to simultaneous equilibration on all
length scales, but requires the determinant of the transformation
as a correction in the Metropolis update rule.

Polarized multiple scattering
The theory of polarization in multiple scattering is very similar
to the theory of writhe in semiflexible polymers, such as DNA:
- Writhing Light in multiple
scattering
- Polarization patterns in back
scattering
- Berry Phases and multiple
scattering
-

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

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

- Two plateau moduli for actin
gels
- Sub-diffusion and
anomalous
- Non-affine effects in
micro-rheology
- 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 semi-diluate
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.
