Group-theoretic treatment of strong light-matter coupling with an arbitrary number of excitations
Antti Peltola, Olli Siltanen, Kimmo Luoma +1
The paper develops a group‑theoretic framework for the Tavis‑Cummings model with any number of excitations, deriving its eigensystem and allowed radiative transitions, and showing…
An Optical Illusion: High Electron Densities Create Extremely Metal-Poor Galaxy Impostors
Tiger Yu-Yang Hsiao, Danielle A. Berg, Steven L. Finkelstein +8
The study shows that some galaxies appear extremely metal-poor when analyzed with low-density assumptions, but accounting for their very high electron densities reveals higher true…
ConceptGuard: Benchmarking Context-Sensitive Unlearning in Large Language Models
Sahil Kale, Ian Harris
Large Language Models (LLMs) increasingly require selective removal of harmful or sensitive knowledge, called unlearning, yet existing methods and benchmarks fail to evaluate this…
Information on trajectories: martingales and random times
Akshay Balsubramani
Accounting for information flow on the path space of trajectories of a nonnegative martingale yields exact variational identities for it, even at arbitrary random times. This recov…
WithEveryone: Unified Planning and Identity Grounding for Group Image Generation
Hengyuan Xu, Qixun Wang, Yiji Cheng +5
Identity-preserving image generation becomes increasingly unreliable when a scene must contain many specified people. Beyond retaining each identity, the model must bind every refe…
4DAnyone: Create Anyone in 4D from a Casual Monocular Video
Yudong Jin, Tao Xie, Qihang Zhang +6
We present 4DAnyone, a framework for reconstructing 4D humans from an uncalibrated monocular video by generating reconstruction-grade multiview-consistent videos and lifting them i…
