One-Dimensional Line Defect

Authors: George Rajna

Professor Wang Ziqiang's group at Boston College proposed a possible theoretical explanation by extending the band theory of the Shockley surface state to the case of superconductors. [26] Recently, studies focusing on systems outside of thermal equilibrium have led to the discovery of new phases in periodically driven quantum systems, the most well-known of which is the discrete time crystal (DTC) phase. [25] Yale physicists have uncovered hints of a time crystal—a form of matter that "ticks" when exposed to an electromagnetic pulse—in the last place they expected: a crystal you might find in a child's toy.
