Engineering cubic quantum nondemolition Hamiltonian with mesoscopic optical parametric interactions

Posted by Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Ryotatsu Yanagimoto, Rajveer Nehra, Edwin Ng, Alireza Marandi, Hideo Mabuchi | Summary: We propose a scheme to realize cubic quantum nondemolition (QND) Hamiltonian with optical parametric interactions. We show that strongly squeezed fundamental and second harmonic fields propagating in a $chi^{(2)}$ nonlinear medium effectively evolve under a […]

Seeing is Believing: Brain-Inspired Modular Training for Mechanistic Interpretability

Posted by klaurent MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Eric Gan, Max Tegmark, , | Summary: We introduce Brain-Inspired Modular Training (BIMT), a method for making neural networks more modular and interpretable. Inspired by brains, BIMT embeds neurons in a geometric space and augments the loss function with a cost proportional to the length […]

Correcting for Interference in Experiments: A Case Study at Douyin

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Vivek F. Farias, Hao Li, Tianyi Peng, Xinyuyang Ren, Huawei Zhang | Summary: Interference is a ubiquitous problem in experiments conducted on two-sided content marketplaces, such as Douyin (China’s analog of TikTok). In many cases, creators are the natural unit of experimentation, but creators interfere with each […]

Surface oxides, carbides, and impurities on RF superconducting Nb and Nb3Sn: A comprehensive analysis

Posted by dbos Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Zeming Sun, Zhaslan Baraissov, Catherine A. Dukes, Darrah K. Dare, Thomas Oseroff | Summary: Surface structures on radio-frequency (RF) superconductors are crucially important in determining their interaction with the RF field. Here we investigate the surface compositions, structural profiles, and valence distributions of oxides, carbides, and […]

Automatic Discovery of Cognitive Strategies with Tiny Recurrent Neural Networks

Posted by klaurent UCSD / Salk

Kavli Affiliate: Marcelo Mattar | Authors: Li Ji-An, Marcus K Benna and Marcelo G Mattar | Summary: Normative frameworks such as Bayesian inference and reward-based learning are useful tools for explaining the fundamental principles of adaptive behavior. However, their ability to describe realistic animal behavior is limited by the often small number of parameters that […]

Resolving the muon $g-2$ tension through $Z’$-induced modifications to $σ_{mathrm{had}}$

Posted by Chicago

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Nina M. Coyle, Carlos E. M. Wagner, , , | Summary: The QED hadronic vacuum polarization function plays an important role in the determination of precision electroweak observables and of the anomalous magnetic moment of the muon. These contributions have been computed from data, by […]

Inspiraling streams of enriched gas observed around a massive galaxy 11 billion years ago

Posted by klaurent Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Shiwu Zhang, Zheng Cai, Dandan Xu, Rhythm Shimakawa, Fabrizio Arrigoni Battaia | Summary: Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas-the reaccretion of gas that was previously ejected from a galaxy-could sustain star formation […]
