A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Physicists have finally turned a long standing thought experiment into a laboratory reality, showing that electromagnetic waves can be reflected in time as cleanly as light bounces off a mirror in ...

New research uncovers remarkable quantum optical phenomena which may enhance quantum technology and paves the road for an exciting nascent field: four-dimensional quantum optics. (Nanowerk News) A new ...
