متن کاملCharge distribution in two-dimensional electrostatics.
We examine the stability of ring-like configurations of N charges on a plane interacting through the potential V (z 1 ,. .. , z N) = |z i | 2 − i<j ln |z i − z j | 2. We interpret the equilibrium distributions in terms of a shell model and compare predictions of the model with the results of numerical simulations for systems with up to 100 particles. Determining the distributions of charged par...
متن کاملInteraction between two Fuzzy Spheres
We have calculated interactions between two fuzzy spheres in 3 dimension. It depends on the distance r between the spheres and the radii ρ1, ρ2. There is no force between the spheres when they are far from each other (long distance case). We have also studied the interaction for r = 0 case. We find that an attractive force exists between two fuzzy sphere surfaces.
متن کاملElectrostatics of two-dimensional structures: Exact solutions and approximate methods
We consider a set of electrostatic problems relevant for determining the real-space structure and the groundstate energy of a two-dimensional electron liquid subject to smooth external potentials. Three fundamental geometries are investigated: an elongated metallic island, an antidot, and a constriction. In the first two cases complete closed-form analytical solutions are obtained, despite the ...
متن کاملCounting faces of cubical spheres modulo two
Several recent papers have addressed the problem of characterizing the f -vectors of cubical polytopes. This is largely motivated by the complete characterization of the f -vectors of simplicial polytopes given by Stanley, Billera, and Lee in 1980 [19] [4]. Along these lines Blind and Blind [5] have shown that unlike in the simplicial case, there are parity restrictions on the f -vectors of cub...
