Winding angles of long lattice walks
Yosi Hammer, Yacov Kantor
We study the winding angles of random and self-avoiding walks on square and cubic lattices with number of steps ranging up to . We show that the mean square winding angle…
Long Polymers Near Wedges and Cones
Yosi Hammer, Yacov Kantor
We perform a Monte Carlo study of -step self-avoiding walks, attached to the corner of an impenetrable wedge in two dimensions (), or the tip of an impenetrable cone in $d=…
Entropic pressure in lattice models for polymers
Yosi Hammer, Yacov Kantor
In lattice models local pressure on a surface is derived from the change in the free energy of the system due to the exclusion of a certain boundary site, while the total force on…
Ideal Polymers near Scale-Free Surfaces
Yosi Hammer, Yacov Kantor
The number of allowed configurations of a polymer is reduced by the presence of a repulsive surface resulting in an entropic force between them. We develop a method to calculate th…
