Delocalization of two interacting particles in a random potential: one-dimensional electric interaction

We consider a continuous one dimensional model of two charged interacting particles in a random potential. The electric repulsion is strictly one dimensional and it inhibits Anderson localization. In fact, the spectrum is continuous. The case of electrical attraction is briefly studied and it shows bounded states. So, the dynamics is sign-dependent for this model.We support our analytical resul...

Colloidal particles at liquid interfaces.

Direct measurements of the effects of salt and surfactant on interaction forces between colloidal particles at water-oil interfaces.

The forces between colloidal particles at a decane-water interface, in the presence of low concentrations of a monovalent salt (NaCl) and the surfactant sodium dodecyl sulfate (SDS) in the aqueous subphase, have been studied using laser tweezers. In the absence of electrolyte and surfactant, particle interactions exhibit a long-range repulsion, yet the variation of the interaction for different...
