The fundamental symmetries of parity and time are now being exploited to enable the spatial guiding and selection of propagating radiation, and could ultimately underpin a new generation of ...

A novel type of nonlinear symmetry breaking in symmetric plasmonic oligomers is reported. By monitoring the strength of the second-harmonic signal while changing the polarization angle of the pump, we ...

The description for the book is also helpful for context. It reads, “Butterfly is one of Project Delta’s deep cover agents, no birth certificate, no social security number, a complete ghost.

As the cell width increases, interface fluctuations, symmetry breaking, and asynchronous nucleation become increasingly prominent. Credit: Advanced Science (2025). DOI: 10.1002/advs.202503807 ...

The butterfly trail should create a series of "stopover" habitats along the monarchs’ migration route through Missouri, giving them places to rest and refuel along the way, Althoff explained. The ...
