Speaker: Prof. GENG Weihua (Southern Methodist University)Venue: Room 105, Building 2, Haina Court, Zijingang CampusAbstract: This talk reports our recent development of numerical methods and software for the studies of electrostatic interactions of solvated biomolecules. The adopted mathematical models for the physical description of biomolecular electrostatics are the Poisson-Boltzmann model and the Poisson-Nernst-Planck model at various of details. The solutions to these models are numerically challenging due to long-range pairwise interaction, complex geometry, interface discontinuity, charge singularity, large-scale computing, etc. We designed and developed methods of fast summation, mesh generation, interface treatment, charge regularity, as well as parallel computing and machine learning to address these challenges.Contact person: Prof. ZHANG Qinghai (0015089@zju.edu.cn)

Speaker: Yuming Zhao (Institute for Quantum Computing and the Department of Pure Mathematics, University of Waterloo, Canada)Location: Dingding Group "2023-Autumn Quantum Theory Group"Abstract: A multivariate polynomial is said to be positive if it takes only non-negative values over reals. Hilbert's 17th problem concerns whether every positive polynomial can be expressed as a sum of squares of other polynomials. In general, we say a noncommutative polynomial is positive (resp. matrix positive) if plugging operators (resp. matrices) always yields a positive operator. Many problems in math and computer science are closely connected to deciding whether a given polynomial is positive and finding certificates (e.g., sum-of-squares) of positivity.In the study of nonlocal games in quantum information, we are interested in tensor product of free algebras. Such an algebra models a physical system with two spatially separated subsystems, where in each subsystem we can make different quantum measurements. The recent and remarkable MIP*=RE result shows that it is undecidable to determine whether a polynomial in a tensor product of free algebras is matrix positive. In this talk, I'll present joint work with Arthur Mehta and William Slofstra, in which we show that it is undecidable to determine positivity in tensor product of free algebras. As a consequence, there is no sum-of-square certificate for positivity in such algebras. I will also discuss relevant topics including self-testing of quantum systems and delegation of quantum computation.Profile of the speaker: Yuming Zhao is a Ph.D. candidate in the Institute for Quantum Computing and the Department of Pure Mathematics at the University of Waterloo, supervised by William Slofstra. Previously, he received his bachelor's degree in Mathematics and Applied Mathematics from Zhejiang University in 2019, under the supervision of Junde Wu. He is broadly interested in the mathematics of quantum information and computation. Recent areas of study include quantum self-testing, delegation of quantum computation, complexity theory in operator algebras, and approximate representation theory.Contact person: Junde Wu (wjd@zju.edu.cn)

Speaker: Prof. ZHONG Ping (University of Wyoming)Venue: Online (Tencent Meeting ID: 974-516-332)Abstract:In the 1980s, L. Brown introduced an analogue of eigenvalue distribution of a square matrix in the framework of operator algebras, now called Brown measure. The Brown measure is a fascinating object that has successful applications in operator algebras and non-Hermitian random matrix theory. The Brown measures of random variables in free probability theory can often predict the limiting eigenvalue distributions of non-Hermitian random matrices.I will speak on joint work with Hari Bercovici on the Brown measure of a sum of two free random variables, one of which is R-diagonal. This answers an open question of Biane and Lehner posed in early 2000s. It is shown that subordination functions that appear in the study of free additive convolution can detect some information about the Brown measure. In many cases, this leads to an explicit calculation of Brown measures. Some ideas were used implicitly in earlier works of Dykema, Haagerup and Schultz. In another joint work with Ching-Wei Ho, we prove that the Brown measure is the limiting eigenvalue distribution of a full rank perturbation of the single ring random matrix model under some mild assumptions.Contact person: Prof. LIU Weihua (lwh.math@zju.edu.cn)
