But in recent years, theorists have found surprising results for a scenario in which one assumes that a particle such as an electron hops between neighboring sites in a periodic lattice asymmetrically\u2014say, rightward hopping is more probable than leftward hopping. The particle\u2019s quantum states become localized at the edge or surface of the lattice rather than spreading across it. This localization is the NHSE.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A concept based on an exotic effect in periodic structures may be useful for developing future photonic devices.
