$ϕ$-Dwarfs: White Dwarfs probe Quadratically Coupled Scalars
We study ultralight scalar fields with quadratic couplings to Standard-Model fermions and derive strong constraints from white-dwarf mass-radius data. Such couplings source scalar profiles inside compact stars, shift fermion masses, and can produce a new ground state of matter. We analyze couplings to electrons and to nucleons, incorporating composition and finite-temperature effects in white dwarf structure and equations of state. We identify two robust observables: (i) forbidden gaps - ranges…

Local vertices, quadratic propagators and double-copy structure of one-loop integrands from forward limits
By worldsheet approach, $n$-point one-loop integrand can be expressed as a combination of $(n+2)$-point tree-level bi-adjoint scalar (BS) amplitudes under forward limit. The integrands constructed by this approach have two closely related features that are different from conventional Feynman diagrams. First, the denominators of loop propagators are linear functions of the loop momentum. Second, the local vertex expression is not manifest. In our previous work, a systematic approach was proposed…

Economist Justin Wolfers: “Demolishing the East Wing of the WH before finalizing plans for what will be built above its ruins is a near-perfect metaphor for Trump’s approach to economic policy.
The only difference is the wrecking crew doesn’t claim the rubble is evidence of unprecedented growth.”

… Ukraine’s peace negotiators met with the US delegation today, which was led by Sec of State Marco Rubio, special envoy Steve Witkoff, and Trump son-in-law Jared Kushner. After multiple recent revelations about Witkoff being owned by Putin, he looked pretty uncomfortable facing the Ukrainians he has worked so hard to sell out.

Quadratic Programming Approach for Nash Equilibrium Computation in Multiplayer Imperfect-Information Games
There has been significant recent progress in algorithms for approximation of Nash equilibrium in large two-player zero-sum imperfect-information games and exact computation of Nash equilibrium in multiplayer strategic-form games. While counterfactual regret minimization and fictitious play are scalable to large games and have convergence guarantees in two-player zero-sum games, they do not guarantee convergence to Nash equilibrium in multiplayer games. We present an approach for exact computat…

Google has teased 60-second AI videos from Veo, which sounds impressive until you realize that requires not 10x, but 100x the energy of a 6-second clip.

TASP: Topology-aware Sequence Parallelism
Long-context large language models (LLMs) face constraints due to the quadratic complexity of the self-attention mechanism. The mainstream sequence parallelism (SP) method, Ring Attention, attempts to solve this by distributing the query into multiple query chunks across accelerators and enable each Q tensor to access all KV tensors from other accelerators via the Ring AllGather communication primitive. However, it exhibits low communication efficiency, restricting its practical applicability. …

Scaling Spoken Language Models with Syllabic Speech Tokenization
Spoken language models (SLMs) typically discretize speech into high-frame-rate tokens extracted from SSL speech models. As the most successful LMs are based on the Transformer architecture, processing these long token streams with self-attention is expensive, as attention scales quadratically with sequence length. A recent SSL work introduces acoustic tokenization of speech at the syllable level, which is more interpretable and potentially more scalable with significant compression in token len…
