Entropy in the Solid State

Although we often think of crystalline materials as perfect, they can accommodate surprising levels of structural disorder. This isn’t just a curiosity, but leads directly to applications ranging from solid-state refrigeration to switchable dielectrics. I will discuss ways to measure this disorder, and how and why we might want deliberately to introduce it.
