Kai Sun of the University of Michigan is a humble physics professor with ambitious goals. "I'm mainly a paper-and-pencil type of theorist, doing analytical calculations mostly," Sun said. "My interests are pretty broad, but basically searching for new fundamental principles and new phenomena, especially new phenomena and new physics previously believed to be impossible."
While his newest study doesn't quite hit that impossible threshold, it does still update our conception of physical possibilities. A quantum behavior that was thought to be possible only sometimes can actually be readily realized, according to new work by Sun and his colleagues, published in the journal Physical Review X.
Taking advantage of this behavior could help manipulate light and other quantum particles in new ways, which could find applications in emerging fields like quantum computing.
