By cooling an atom-thin magnetic material, physicists have experimentally confirmed a classic 1970s model of two-dimensional ...

Abstract: The purpose of this article is to present two technical contributions geared toward the development of 2-D electrical impedance tomography (EIT) image reconstruction based on deep learning ...

Abstract: In recent years, reconfigurable metasurfaces have received extensive attention, but they are difficult to achieve wideband performance. Here, an ultra-wideband phase reconfigurable ...

Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time ...
