Space-time crystalline order of a high-critical-temperature superconductor with intrinsic Josephson junctions

Abstract

A space-time crystal (STC) is a nonequilibrium phase of matter displaying long-range order in both space and time. Here, the authors propose that the high-T c cuprate superconductor Bi2Sr2CaCu2O8+x is a candidate of a classical discrete STC, when a parametric modulation periodic in time and uniform in space is applied.
