We study a two-species reaction-diffusion system with the reactions $ A+ A\to (0, A) $ and $
A+ B\to A $, with general diffusion constants $ D_A $ and $ D_B $. Previous studies showed …

We perform a Monte Carlo study of N-step self-avoiding walks, attached to the corner of an
impenetrable wedge in two dimensions (d= 2), or the tip of an impenetrable cone in d= 3, of …

We consider the quantum problem of a particle in either a spherical box or a finite spherical
well confined by a circular cone with an apex angle 2θ 0 emanating from the center of the …

We consider forces acting on objects immersed in, or attached to, long fluctuating polymers.
The confinement of the polymer by the obstacles results in polymer-mediated forces that can …

A polymer repelled by unfavorable interactions with a uniform flat surface may still be pinned
to attractive edges and corners. This is demonstrated by considering adsorption of a two …

We consider localization of a random walk (RW) when attracted or repelled by multiple
extended manifolds of different dimensionalities. In particular, we consider a RW near a …

We use Newtonian and overdamped Langevin dynamics to study long flexible polymers
dragged by an external force at a constant velocity v. The work W performed by that force …
