Kavli Affiliate: Wei Gao | First 5 Authors: Kai Huang, Wei Gao, , , | Summary: Text-to-image diffusion models can be fine-tuned in custom domains to adapt to specific user preferences, but such unconstrained adaptability has also been utilized for illegal purposes, such as forging public figures’ portraits and duplicating copyrighted artworks. Most existing work […]

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Rohit Mukherjee, Haoyu Guo, Keiran Lewellen, Debanjan Chowdhury, | Summary: Ergodic quantum many-body systems evolving under unitary time dynamics typically lose memory of their initial state via information scrambling. Here we consider a paradigmatic translationally invariant many-body Hamiltonian of interacting bosons — a Josephson junction array in […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Alexandra G. Hanselman, Aditya Vijaykumar, Maya Fishbach, Daniel E. Holz, | Summary: The detection of GW170817 and the measurement of its redshift from the associated electromagnetic counterpart provided the first gravitational wave determination of the Hubble constant ($H_0$), demonstrating the potential power of standard-siren cosmology. In […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone, Annelotte Derkink, Frank Backs | Summary: The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics. We present follow-up R~40 spectrophotometric monitoring of red companion HD 1160 B at 2.8-4.2 […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Zewei Wu, Andrey Kravtsov, , , | Summary: We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{rm UV}approx -25$ to $M_{rm UV}=-4$ at redshifts $5leq zleq 10$ using a galaxy formation model that reproduces properties of local […]

Kavli Affiliate: Wei Gao | First 5 Authors: Joseph J. P. Simons, Wong Liang Ze, Prasanta Bhattacharya, Brandon Siyuan Loh, Wei Gao | Summary: Digital trace data provide potentially valuable resources for understanding human behaviour, but their value has been limited by issues of unclear measurement. The growth of large language models provides an opportunity […]
Kavli Affiliate: Wei Gao | First 5 Authors: Joseph J. P. Simons, Wong Liang Ze, Prasanta Bhattacharya, Brandon Siyuan Loh, Wei Gao | Summary: Large language models are increasingly being used to label or rate psychological features in text data. This approach helps address one of the limiting factors of digital trace data – their […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Carlos E. Sierra, Kathleen Harrington, Shreya Sutariya, Thomas Alford, Anna M. Kofman | Summary: The Simons Observatory will map the temperature and polarization over half of the sky, at millimeter wavelengths in six spectral bands from the Atacama Desert in Chile. These data will provide new […]
