Anomalous fluctuations of active polar filaments
Tanniemola B. Liverpool
Using a simple model, we study the fluctuating dynamics of inextensible, semiflexible polar filaments interacting with active and directed force generating centres such as molecula…
Organization and instabilities of entangled active polar filaments
Tanniemola B. Liverpool, M. Cristina Marchetti
We study the dynamics of an entangled, isotropic solution of polar filaments coupled by molecular motors which generate relative motion of the filaments in two and three dimensions…
Conformational Instability of Rodlike Polyelectrolytes due to Counterion Fluctuations
Ramin Golestanian, Tanniemola B. Liverpool
The effective elasticity of highly charged stiff polyelectrolytes is studied in the presence of counterions, with and without added salt. The rigid polymer conformations may become…
Statistical mechanics of double-helical polymers
Alvise De Col, Tanniemola B. Liverpool
We introduce a simple geometric model for a double-stranded and double-helical polymer. We study the statistical mechanics of such polymers using both analytical techniques and sim…
