Broadband terahertz comb with sub-Hz comb linewidth
Min Li, Yu Xia, Yuan Chen +6
Terahertz (THz) frequency combs are increasingly essential for spectroscopy, metrology, and quantum science. However, generating a dense array of evenly spaced ultra-narrow THz com…

Reconstructive comb spectroscopy: A single-pixel detection paradigm beyond dual-comb limitations
Dongxu Zhu, Zhuoren Wan, Xiaoshuai Ma +13
Frequency comb spectroscopy has revolutionized broadband molecular fingerprinting with mode-defined resolution. While dual-comb spectroscopy stands as a dominant paradigm for high-…

Intensity correlations in the Wigner representation
Mojdeh S. Najafabadi, Luis L. Sánchez-Soto, Kun. Huang +3
We derive a compact expression for the second-order correlation function of a quantum state in terms of its Wigner function, thereby establishing a direct link betwee…
