Abstract
We study uniform 3-star polymers with one branch tethered to an attractive surface and another branch pulled by a force away from the surface. Each branch of the 3-star lattice is modelled as a self-avoiding walk (SAW) on the simple cubic lattice with one endpoint of each branch joined at a common node. Recent theoretical work van Rensburg and Whittington (2018 J. Phys. A: Math. Theor. 51 204001) found four phases for this system: free, fully adsorbed, ballistic and mixed. The mixed phase occurs between the ballistic and fully adsorbed phase. We investigate this system by using the flatPERM Monte Carlo algorithm with special restrictions on the endpoint moves to simulate 3-stars up to branch..
