Attractive and repulsive dipolar interaction in bilayers of indirect excitons
نویسندگان
چکیده
We explore attractive dipolar interaction in indirect excitons (IXs). For one layer of IXs a single pair coupled quantum wells (CQW), the out-of-plane IX electric dipoles lead to repulsive between IXs. The is realized 2-CQW heterostructure with two layers separated CQW pairs. found both experimental measurements and theoretical simulations that increasing density causes monotonic energy reduction for other layer. also an in-plane shift cloud towards This behaviour qualitatively consistent interaction. measured are higher than values given by correlated liquid theory.

On global minimizers of repulsive–attractive power-law interaction energies
We consider the minimization of the repulsive-attractive power-law interaction energies that occur in many biological and physical situations. We show the existence of global minimizers in the discrete setting and obtain bounds for their supports independently of the number of Dirac deltas in a certain range of exponents. These global discrete minimizers correspond to the stable spatial profile...
متن کاملSoliton-stripe patterns of a functional with an attractive-repulsive-attractive interaction
We study critical points of a Ginzburg-Landau type functional with an attractive-repulsive-attractive nonlocal interaction. Using an appropriate scaling and the Γ-convergence method we reduce the problem to a finite dimensional one. In contrast to a similar problem with just an attractive-repulsive interaction, we obtain a richer set of solutions. The soliton-stripe patterns appear as skewed lo...
متن کاملAsymptotic Dynamics of Attractive-Repulsive Swarms
We classify and predict the asymptotic dynamics of a class of swarming models. The model consists of a conservation equation in one dimension describing the movement of a population density field. The velocity is found by convolving the density with a kernel describing attractive-repulsive social interactions. The kernel’s first moment and its limiting behavior at the origin determine whether t...

Phase imaging of proton exchange membranes under attractive and repulsive tip-sample interaction forces.
The nature of tip-sample interaction forces in atomic force microscopy (AFM) phase imaging strongly affects the resolution of proton conducting domains mapped at the surface of Nafion membranes. Images acquired in repulsive mode overestimated the area of individual proton conducting domains by a factor of 4 (360 vs 90 nm(2)) and underestimated the number of these domains by a factor of 3 (0.9 d...
