Exotic Electrostatics of Charged Disordered Systems
Prof. Ali Naji, School of Physics, Institute for Research in Fundamental Sciences, Tehran, Iran
Standard electrostatic theory as taught in physics textbooks is based primarily on the assumption of uniform distribution for electrical charges in the bulk or on bounding surfaces of materials. In reality, however, charge distributions turn out to be highly heterogeneous or even disordered. We show that charge disorder leads to emergence of distinct phenomena such as extremely long-range interactions even between net-neutral objects, which stands at odds with the commonly accepted views but has indeed been inferred from recent ultrahigh sensitivity measurements of the Casimir force. Such disorder-induced effects could have major implications in other fields as well, most notably, in colloidal science, soft matter and biological physics.
