Quantum material goes where none have gone before

Posted by in categories: mapping, quantum physics

Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he’s finally found a traveler that can traverse the final frontier.

The traveler is an alloy of cerium palladium and aluminum, and its journey is described in a study published online this week in Nature Physics by Si, a and director of the Rice Center for Quantum Materials (RCQM), and colleagues in China, Germany and Japan.

Si’s map is a graph called a , a tool that condensed-matter physicists often use to interpret what happens when a material changes phase, as when a solid block of ice melts into liquid water.
