Winding Angle Distributions for Directed Polymers
Barbara Drossel, Mehran Kardar
We study analytically and numerically the winding of directed polymers of length around each other or around a rod. Unconfined polymers in pure media have exponentially decayin…
A Model for Growth of Binary Alloys with Fast Surface Equilibration
Barbara Drossel, Mehran Kardar
We study a simple growth model for (d+1)-dimensional films of binary alloys in which atoms are allowed to interact and equilibrate at the surface, but are frozen in the bulk. The r…
Freezing Transition of Compact Polyampholytes
Vijay S. Pande, Alexander Yu. Grosberg, Chris Joerg +2
Polyampholytes (PAs) are heteropolymers with long range Coulomb interactions. Unlike polymers with short range forces, PA energy levels have non-vanishing correlations and are thus…
Fluctuation-Induced Interactions between Rods on a Membrane
Ramin Golestanian, Mark Goulian, Mehran Kardar
We consider the interaction between two rods embedded in a fluctuating surface. The modification of fluctuations by the rods leads to an attractive long-range interaction between t…
Conformations of Randomly Linked Polymers
Yacov Kantor, Mehran Kardar
We consider polymers in which M randomly selected pairs of monomers are restricted to be in contact. Analytical arguments and numerical simulations show that an ideal (Gaussian) ch…
