AI에 의해 보고됨
Researchers at the University at Buffalo have expanded the truncated Wigner approximation to simulate complex quantum systems on ordinary laptops, bypassing the need for supercomputers. This advancement, detailed in a September study in PRX Quantum, simplifies quantum dynamics for real-world applications. The method targets dissipative spin dynamics, making advanced physics accessible to more scientists.
Scientists create laptop tool to simulate universe structure
Researchers at the University of Waterloo have developed Effort.jl, a new tool that allows scientists to simulate the universe's large-scale structure using just a laptop. This innovation reduces computation time from days on supercomputers to hours, enabling faster analysis of vast cosmic datasets. The tool emulates complex models like the Effective Field Theory of Large-Scale Structure (EFTofLSS).
