photonic time crystals remain uniform in space but exhibit a periodic oscillation in time. This distinctive quality creates "momentum band gaps," or unusual states where light pauses inside the ...

High harmonic generation (HHG) is a highly non-linear phenomenon where a system (for example, an atom) absorbs many photons ...

The new 2D halide perovskites also exhibit a dynamic 'switchable' behaviour. The researchers found that one of the ...

You’ve reached your account maximum for followed topics. Star Trek showcases encounters with non-corporeal photonic lifeforms, challenging perceptions of sentience in the universe. Sentient ...

Kramers-Kronig (KK) algorithm could effectively eliminate SSBI. In this study, we demonstrated the feasibility of adaptive KK (AKK) in a simplified coherent photonics-aided terahertz system in the ...

The researchers “looked at creating a new class of materials with increased “band gap,” enhancing both transparency and conductivity. The new material is a transparent conducting oxide, created with a ...

Semiconductors power nearly all electronics, from smartphones to medical devices. A key to advancing these technologies lies in improving what scientists refer to as "ultra-wide band gap" materials.
