The experimental validation reported in this study by Díaz-Rubio et al. is the first implementation of an anomalous reflective acoustic metamirror that could overcome the efficiency limits of the previous GSL-based designs.  Physicists at the National Institute of Standards and Technology (NIST) have "flash-frozen" a flat crystal of 150 beryllium ions (electrically charged atoms), opening new possibilities for simulating magnetism at the quantum scale and sensing signals from mysterious dark matter.
