Gravity of gluonic fluctuations and the value of the cosmological constant

Kavli Affiliate: Craig Hogan | First 5 Authors: Kris Mackewicz, Craig Hogan, , , | Summary: We analyze the classical linear gravitational effect of idealized pion-like dynamical systems, consisting of light quarks connected by attractive gluonic material with a stress-energy $p=-rho c^2$ in one or more dimensions. In one orbit of a system of total […]

Engineering cubic quantum nondemolition Hamiltonian with mesoscopic optical parametric interactions

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

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

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 […]

Automatic Discovery of Cognitive Strategies with Tiny Recurrent Neural Networks

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 […]
