Complex-Valued-Matrix Permanents: SPA-based Approximations and Double-Cover Analysis
Junda Zhou, Pascal O. Vontobel
Approximating the permanent of a complex-valued matrix is a fundamental problem with applications in Boson sampling and probabilistic inference. In this paper, we extend factor-gra…

A Core-Collapse Supernova Neutrino Parameterization with Enhanced Physical Interpretability
Haihao Shi, Zhenyang Huang, Junda Zhou +2
We introduce a novel parameterization of supernova neutrino energy spectra with a clear physical motivation. Its central parameter, , quantifies the characteristic thermal-di…

Dark Matter (S)pins the Planet
Haihao Shi, Junda Zhou, Zhenyang Huang +2
Dark matter heating in planets has been proposed as a potential probe for dark matter detection. Assuming near-equilibrium conditions, we find that the energy input from dark matte…
