36. Lattice QCD gauge configuration generation at near physical point

Prof. 玮 孙 (高能所)

02/11/2021, 16:00

The solve of Dirac equation for light quarks in lattice QCD suffered from the critical mass slowing down problem, which can be solved by the recently developed multigrid method. In this talk, I will discuss the techniques and algorithms in lattice QCD gauge configuration generation, and combine the HMC and multigrid algorithm to speed up the gauge configuration generation at near physical point.

37. Machine learning spectral functions in lattice QCD

世阳 陈

We study the inverse problem of reconstructing spectral functions from Euclidean correlators via machine learning. We propose a novel neutral network, sVAE, which is based the variational autoencoder (VAE) and can be naturally applied to study the inverse problem. The prominent feature of the sVAE is that a Shannon-Jaynes entropy term having the ground truth values of spectral functions as...

38. Lattice realization of $\xi$ gauge

春江 施

02/11/2021, 16:50

We perform a lattice implement of $\xi$ gauge, a more general covariant gauge. We will present the performance of our lattice realization in $\xi$ gauge and primary results of gluon propagators and dynamical overlap quark propagators with $\xi \in [0, 0.2]$. We calculate several renormalization constants under $\xi$ gauge configurations and discuss the gauge invariance under the MS-bar scheme...

39. Propagator generation with Chroma+QUDA for various fermion actions

宽 张 (ITP)

02/11/2021, 17:10

We will present how to calculate propagators on Chroma with overlap and HISQ (highly improved staggered quark) valence quark, which are not fully supported on Chroma before. For overlap, we setup the fermion action based on polynomials of hwilson action, create overlap dslash on QUDA, migrate Arnoldi algorithm from gwu-code to solve the eigensystem for deflation, and migrate multishift...
