Dear All,
This is just a reminder that our first joint Theory Seminar is today at 4pm
in M102 - Division Room.
Best,

Dear Professors,
On behalf of the Heller Group, Visiting Scholar Professor Michael Herman of
Tulane University, will be presenting the first Theory Seminar next Monday,
24 November from 4-5pm in the Division Room (Mallinckrodt 102). Please
encourage your group members to attend.
*Accounting for Correlated Many Chain Motions in the Dynamics of Polymers
in the Melt*
*Michael F. Herman*
*Department of Chemistry*

Abstract:
A theory of melt polymer dynamics that accounts for correlated many chain
motions is developed. It is shown that this theory reproduces the
experimentally observed molecular weight dependence of the diffusion
constant and the viscosity for linear chains and rings. Results for the
relaxation in monodisperse and bidisperse melts are also presented. The
short time, short chain motion of the polymer chains, calculated from force
field molecular dynamics, are used in the theory to predict the long time,
long chain diffusion without adjustable parameters.
Our next seminar will be presented by Dr. Jingzhi Pu of the Karplus Group
on Tue 9 Dec at 4:15pm. An announcement will be sent in early December.
Thank you!
Anna
