Reaching the Ultimate Quantum Precision Limit at Colliders: Conditions and Case Studies

Kavli Affiliate: Jia Liu | First 5 Authors: Tengyu Ai, Qi Bi, Yuxin He, Jia Liu, Xiao-Ping Wang | Summary: We investigate whether collider experiments can reach the quantum limit of precision, defined by the quantum Fisher information (QFI), using only classical observables such as particle momenta. As a case study, we focus on the […]

The Fast and the Frame-Dragging: Efficient waveforms for asymmetric-mass eccentric equatorial inspirals into rapidly-spinning black holes

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Christian E. A. Chapman-Bird, Lorenzo Speri, Zachary Nasipak, Ollie Burke, Michael L. Katz | Summary: Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient waveform models. Intermediate- and extreme-mass-ratio inspirals (I/EMRIs), with mass […]

Analysis of Anonymous User Interaction Relationships and Prediction of Advertising Feedback Based on Graph Neural Network

Kavli Affiliate: Feng Yuan | First 5 Authors: Yanjun Dai, Haoyang Feng, Yuan Gao, , | Summary: While online advertising is highly dependent on implicit interaction networks of anonymous users for engagement inference, and for the selection and optimization of delivery strategies, existing graph models seldom can capture the multi-scale temporal, semantic and higher-order dependency […]

Dynamics of low-mass black hole seeds in the BRAHMA simulations using subgrid-dynamical friction: Impact on merger-driven black hole growth in the high redshift Universe

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Luke Z. Kelley, Aneesh Sivasankaran, Paul Torrey | Summary: We analyze the dynamics of low-mass black hole (BH) seeds in the high-redshift ($zgtrsim5$) Universe using a suite of $[4.5~mathrm{Mpc}]^3$ and $[9~mathrm{Mpc}]^3$ BRAHMA cosmological hydrodynamic simulations. The simulations form seeds with mass $M_{mathrm{seed}}=2.2times10^3~M_{odot}$ […]
