Spectral methods are very efficient numerical algorithms for solving partial differential equations in relatively simple geometries. The numerical errors introduced by spectral algorithms typically ...

TSRS boosts the sensitivity of SRS to sub-mM level while maintaining the nature-linewidth-limit spectral lines. This method may find applications in high-density bio-orthogonal labeling, ...

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, ...
