Kavli Affiliate: Nickolay Gnedin | Summary:Recently, several observational detections of damping-wing-like features at the edges of “dark gaps" in the spectra of distant quasars (the “Malloy-Lidz effect") have been reported, rendering strong support for the existence of “neutral islands" in the universe at redshifts as low as $z<5.5$. We apply the procedure from one of […]

Kavli Affiliate: Ran Wang | First 5 Authors: Haiming Wang, Mert Unsal, Xiaohan Lin, Mantas Baksys, Junqi Liu | Summary: We introduce Kimina-Prover Preview, a large language model that pioneers a novel reasoning-driven exploration paradigm for formal theorem proving, as showcased in this preview release. Trained with a large-scale reinforcement learning pipeline from Qwen2.5-72B, Kimina-Prover […]
Kavli Affiliate: Gang Su | First 5 Authors: Junsen Xiang, Chuandi Zhang, Yuan Gao, Wolfang Schmidt, Karin Schmalzl | Summary: Supersolid, an exotic quantum state of matter that consists of particles forming an incompressible solid structure while simultaneously showing superfluidity of zero viscosity [1], is one of the long-standing pursuits in fundamental research [2, 3]. […]
Kavli Affiliate: T. Higuchi | First 5 Authors: , , , , | Summary: We report measurements of the ratios of branching fractions $cal R(D^(*)+) = fraccal B(overlineB^0 to D^(*)+ ,tau^- , overlinenu_tau)cal B(overlineB^0 to D^(*)+ , ell^- , overlinenu_ell)$, where $ell$ denotes either an electron or a muon. These ratios test the universality of […]
Kavli Affiliate: Long Zhang | First 5 Authors: Peipei Song, Long Zhang, Long Lan, Weidong Chen, Dan Guo | Summary: Partially relevant video retrieval (PRVR) is a practical yet challenging task in text-to-video retrieval, where videos are untrimmed and contain much background content. The pursuit here is of both effective and efficient solutions to capture […]
Kavli Affiliate: Yi Zhou | First 5 Authors: , , , , | Summary: We present a comprehensive study of topological phases in the SO($n$) spin chains using a combination of analytical parton construction and numerical techniques. For even $n=2l$, we identify a novel SPT$^2$ phase characterized by two distinct topological sectors, exhibiting exact degeneracy […]
