Frequency Modulation of Gravitational Waves by Ultralight Scalar Dark Matter

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Yin Zhong, , , | Summary: The oscillating pressure of the ultralight scalar dark matter (DM) can induce the oscillation of the local gravitational potential. Similar to the time-dependent frequency shift for the pulse signals of pulsars, the oscillation of the local gravitational potential can […]

High-coherence hybrid-integrated 780 nm source by self-injection-locked second-harmonic generation in a high-Q silicon-nitride resonator

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Bohan Li, Zhiquan Yuan, Warren Jin, Lue Wu, Joel Guo | Summary: By self-injection-locking a 1560 nm distributed feedback semiconductor laser to a high-$Q$ silicon nitride resonator, a high-coherence 780 nm second harmonic signal is generated via the photogalvanic-induced second-order nonlinearity. A record-low frequency noise floor […]

No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c

Kavli Affiliate: Laura Schaefer | First 5 Authors: , , , , | Summary: Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017). Thanks to the recent launch of JWST, possible atmospheric constituents such as carbon […]
