Kavli Affiliate: Ke Wang | First 5 Authors: Zehua Chen, Xu Tan, Ke Wang, Shifeng Pan, Danilo Mandic | Summary: Denoising diffusion probabilistic models (diffusion models for short) require a large number of iterations in inference to achieve the generation quality that matches or surpasses the state-of-the-art generative models, which invariably results in slow inference […]
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michelle Kunimoto, Joshua N. Winn, George R. Ricker, Roland Vanderspek, | Summary: The Transiting Exoplanet Survey Satellite (TESS) has discovered $sim$5000 planets and planet candidates after three and a half years of observations. With a planned second Extended Mission spanning Years 5 – 7 on the horizon, […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Ruijin Liu, Cheng Peng, Xiaoling Cui, , | Summary: Identifying few-body correlations is an efficient tool to solve complex many-body problems. The polarons, interpolating between few- and many-body systems, serve as an ideal platform to achieve the goal. In this work, we reveal various crystalline few-body correlations […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Quang Minh Nguyen, Hoang H. Nguyen, Yi Zhou, Lam M. Nguyen, | Summary: We study the Unbalanced Optimal Transport (UOT) between two measures of possibly different masses with at most $n$ components, where marginal constraints of the standard Optimal Transport (OT) are relaxed via Kullback-Leibler divergence with […]

Kavli Affiliate: Roger W. Romani | First 5 Authors: Martijn de Vries, Roger W. Romani, , , | Summary: New X-ray and optical observations shed light on the remarkable X-ray filament of the Gamma-ray pulsar PSR~J2030+4415. Images of the associated H$alpha$ bow shock’s evolution over the past decade compared with its velocity structure provide an […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Kang Yang, Daniel Varjas, Emil J. Bergholtz, Sid Morampudi, Frank Wilczek | Summary: We show that interactions in quantum spin liquids can result in non-Hermitian phenomenology that differs qualitatively from mean-field expectations. We demonstrate this in two prominent cases through the effects of phonons and disorder on […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Peter Abbamonte, Daniel Baxter, Yonatan Kahn, Gordan Krnjaic, Noah Kurinsky | Summary: In light of recent results from low-threshold dark matter detectors, we revisit the possibility of a common dark matter origin for multiple excesses across numerous direct detection experiments, with a focus on the excess rates […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Xiangyu Peng, Kai Wang, Zheng Zhu, Mang Wang, Yang You | Summary: Recent self-supervised contrastive learning methods greatly benefit from the Siamese structure that aims at minimizing distances between positive pairs. For high performance Siamese representation learning, one of the keys is to design good contrastive pairs. […]
