Parametric Instability Rates in Periodically Driven Band Systems

May 8, 2017

At very low temperatures, quantum matter can show radically different, and often counterintuitive, behavior compared to traditional liquids, solids, and gases. Such quantum phases of matter (e.g., superfluids and superconductors) are used in practical applications such as levitating trains and medical imaging. In the field of quantum simulation, researchers are attempting to engineer phases of matter that are even more exotic. One appealing approach is to start with a standard quantum fluid and "drive it" by shaking it, rotating it, or subjecting it to an external field. However, this method faces a serious difficulty: the phase is unstable.

Dr. David Morin's new book, Special Relativity: For the Enthusiastic Beginner, is written for high school and college students learning about special relativity for the first time. It will appeal to the reader who has a healthy level of enthusiasm for understanding how and why the various results of special relativity come about.
