Quantum Simulation with cold atoms is a very ambitious program in AMO research that is being pursued in many laboratories worldwide. The goal is to use cold atoms in optical lattices and in different environment to simulate important yet unsolved theoretical models. In this talk, I shall review the current progress of this effort, its success, and the serious challenges it faces. I shall discuss the possible solutions and the exciting future it holds.

Analyses of the Remora Adhesion System

Remoras (echeneid fish) reversibly attach and detach to marine hosts, almost instantaneously, to “hitchhike” and feed. The adhesion mechanisms that they use are remarkably insensitive to substrate topology and quite different from the latching and suction cup-based systems associated with other species at similar length scales. Remora adhesion is also anisotropic; drag forces induced by the host’s swimming increase adhesive strength, while rapid detachment occurs when the remora reverses this shear load. In this presentation, an investigation of the adhesive system’s...

Soft matter, food and cooking

Have you ever wondered why an egg solidifies at high temperature while most pure substances, like water, do not? Or why materials solely made of liquids can exhibit solid-like properties? Or why adding a tiny amount of certain additives to water dramatically changes the way water flows? This talk will touch on some of these aspects. It will start by discussing what soft condensed matter is and why soft materials are indeed soft. It will then briefly discuss viscous flow, to end introducing the significance of phase transformations in manipulating food. The aim of the...
