Causal Forcing++: Scalable Few-Step Autoregressive Diffusion Distillation for Real-Time Interactive Video Generation
Min Zhao, Hongzhou Zhu, Kaiwen Zheng +6
Real-time interactive video generation requires low-latency, streaming, and controllable rollout. Existing autoregressive (AR) diffusion distillation methods have achieved strong r…
gwBenchmarks: Stress-Testing LLM Agents on High-Precision Gravitational Wave Astronomy
Tousif Islam, Digvijay Wadekar, Zihan Zhou
Modern gravitational wave astronomy relies on modeling tasks that often require months of graduate-level effort, including building fast waveform surrogates from expensive numerica…
Core-Halo Decomposition: Decentralizing Large-Scale Fixed-Point Problems
Haixiang, Yang Xu, Jiefu Zhang +4
We study solving large-scale fixed-point equation \(x^\star=\bar F(x^\star)\) with decomposition. Standard strict decomposition assigns each agent a disjoint block and evaluates up…
Gravitational Sommerfeld Effects: Formalism, Renormalization, and Perturbation to
Chih-Hao Chang, Chia-Hsien Shen, Zihan Zhou
In the effective field theory (EFT) description of binary inspirals, the radiated gravitational waveform receives universal corrections from the curved background, the so-called ``…
Resummation of Universal Tails in Gravitational Waveforms
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a formula for the universal anomalous scaling of the multipole moments of a generic gravitating source in classical general relativity. We derive this formula in two ind…
Bring the Heat: Tidal Heating Constraints for Black Holes and Exotic Compact Objects from the LIGO-Virgo-KAGRA Data
Horng Sheng Chia, Zihan Zhou, Mikhail M. Ivanov
We present the first constraints on tidal heating for the binary systems detected in the LIGO-Virgo-KAGRA (LVK) gravitational wave data. Tidal heating, also known as tidal dissipat…
