A recent study from the (UEF) examines how photons—the fundamental particles of light—behave when they encounter sudden ...

"This work could lead to the first experimental realization of photonic time crystals, propelling them ... this research challenges the boundaries of how we can control the light-matter ...

Every time a wave crosses a boundary between two crystals, known as a grain boundary, it loses energy. If the crystals are smaller, there are more of these grain boundaries in a given volume.
