Quantum state preparation and macroscopic entanglement in gravitational-wave detectors
Helge Mueller-Ebhardt, Henning Rehbein, Chao Li +5
Long-baseline laser-interferometer gravitational-wave detectors are operating at a factor of 10 (in amplitude) above the standard quantum limit (SQL) within a broad frequency band.…

The trispectrum of 21-cm background anisotropies as a probe of primordial non-Gaussianity
Asantha Cooray, Chao Li, Alessandro Melchiorri
The 21-cm anisotropies from the neutral hydrogen distribution prior to the era of reionization is a sensitive probe of primordial non-Gaussianity. Unlike the case with cosmic micro…
