107 possibilities of better for testing of universal concepts of quantum and nonlinear physics. Another significant portion of our research is aimed at the development of new imaging and inspection techniques based on quantum and nonlinear phenomena. It is expected that these techniques will offer the ability to image and inspect phenomena and small objects on the atomic scale resolution.

Abstract Experimental Soft Condensed Matter Physics Our team studies the physics of soft matter, such as emulsions and colloidal suspensions. Despite the prevalence of these materials in everyday life, a fundamental physical understanding of their properties is still lacking. To study these materials, we employ cutting-edge light and electron microscopy methods, optical tweezers’ manipulation, and light scattering. Currently, we mainly focus on a unique and counterintuitive phenomenon, discovered by our team a few years ago: a spontaneous, temperature-controlled sphere-to-polyhedron shape transition of emulsion droplets, the bulk of which remains liquid. The mechanism of this new phenomenon plays an important role in a wide range of chemical and biological systems, and enables the formation of faceted building blocks in a wide range of sizes, from nanometers to millimeters, of high promise for future materials. However, the fundamental understanding of nanoscale interfacial elasticity, which controls the studied phenomena, is yet unavaialalbe. Establishing such understanding is the aim of our current work. A temperature-tunable concave–convex shape transition of capillary-contained oilwater interfaces, discovered by Sloutskin’s team, owes to self-assembly of a 2 nmthick interfacial crystal.
