New limits on the local Lorentz invariance violation of gravity in the Standard-Model Extension with pulsars

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Ziming Wang, Lijing Shao, , | Summary: Lorentz Violation (LV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LV. With their high observational accuracy, pulsars […]

New $μ$ Forces From $ν_μ$ Sources

Posted by Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Cari Cesarotti, Yonatan Kahn, Gordan Krnjaic, Duncan Rocha, Joshua Spitz | Summary: Accelerator-based experiments reliant on charged pion and kaon decays to produce muon-neutrino beams also deliver an associated powerful flux of muons. Therefore, these experiments can additionally be sensitive to light new particles that preferentially couple […]

Direct Optimal Mapping Image Power Spectrum and its Window Functions

Posted by dbos MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Honggeun Kim, Jacqueline N. Hewitt, Kai-Feng Chen, Nicholas S. Kern | Summary: The key to detecting neutral hydrogen during the epoch of reionization (EoR) is to separate the cosmological signal from the dominating foreground radiation. We developed direct optimal mapping (DOM) to map interferometric […]

On the nature of screening in charge regulated macroion solutions

Posted by dbos UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Sunita Kumari, Rudolf Podgornik, , , | Summary: We present a derivation of the screening length for a solution containing a charge regulated macroion, e.g. protein, with its counterions. We show that it can be obtained directly from the second derivatives of the total free energy by […]

FOAL: Fine-grained Contrastive Learning for Cross-domain Aspect Sentiment Triplet Extraction

Posted by dbos Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Ting Xu, Zhen Wu, Huiyun Yang, Xinyu Dai, | Summary: Aspect Sentiment Triplet Extraction (ASTE) has achieved promising results while relying on sufficient annotation data in a specific domain. However, it is infeasible to annotate data for each individual domain. We propose to explore ASTE in the […]

Tunable Inter-Moiré Physics in Consecutively-Twisted Trilayer Graphene

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Wei Ren, Konstantin Davydov, Ziyan Zhu, Jaden Ma, Kenji Watanabe | Summary: We fabricate a twisted trilayer graphene device with consecutive twist angles of 1.33 and 1.64 degrees, in which we electrostatically tune the electronic states from each of the two co-existing moir’e superlattices and the interactions […]

Giant Outer Transiting Exoplanet Mass (GOT ‘EM) Survey: III. Recovery and Confirmation of a Temperate, Mildly Eccentric, Single-Transit Jupiter Orbiting TOI-2010

Posted by dbos MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Christopher R. Mann, Paul A. Dalba, David Lafrenière, Benjamin J. Fulton, Guillaume Hébrard | Summary: Large-scale exoplanet surveys like the TESS mission are powerful tools for discovering large numbers of exoplanet candidates. Single-transit events are commonplace within the resulting candidate list due to the unavoidable limitation […]
