Xiansheng Cai
Xiansheng Cai is a PH.D. student at the Physics department of University of Massachusetts Amherst. He is actively involved in the development of Julia packages under the Numerical Effective Field Theory (NEFT) framework(https://github.com/numericalEFT) for modeling real-world quantum materials using modern quantum field theory. As the leading designer, his efforts have resulted in the creation of powerful tools CompositeGrids.jl for 1D grid representation, BrillouinZoneMeshes.jl for multi-dimensional Brillouin zone meshgrid representation.

High-dimensional Monte Carlo Integration with Native Julia
This talk presents a new Julia package for efficient and generic Monte Carlo integration in high-dimensional and complex domains, featuring the Vegas algorithm for self-adaptive important sampling and an improved algorithm for increased robustness. The package demonstrates Julia's superiority over C/C++/Fortran and Python for high-dimensional Monte Carlo integration by enabling the easy creation of user-defined integrand evaluation functions with the speed of C and the flexibility of Python.
