NERSC User Meeting: William Detmold - The Standard Model of Particle and Nuclear Physics at Exascale

William Detmold, Professor of Physics, Massachusetts Institute of Technology Abstract I will discuss the long-running and central role that supercomputing has played in defining and testing the Standard Model in particle and nuclear physics through the numerical approach of lattice quantum chromodynamics (LQCD). LQCD describes the interactions of the quarks and gluons that combine to for composite states such as the proton, and from early crude calculations of the particle masses, to precision test of the Standard Model through theory—experiment comparisons, LQCD has always been at the forefront of applications of HPC at NERSC and elsewhere. In this talk I will discuss some history and recent results from the field, focusing on problems related to the emergence on complex systems such as nuclei and dense matter from the underlying quark and gluon degrees of freedom and provide an outlook for the future. Speaker Bio Detmold did his undergraduate and graduate studies at the University of Adelaide, Australia, and after spending time at the University of Washington and College of William and Mary has been a Professor of Physics at MIT since 2012. His research interests are in strong interaction dynamics in theoretical particle and nuclear physics. Detmold uses analytic methods and supercomputers to solve the complex equations of quantum chromodynamics (QCD) that describe the strong interaction and seeks to understand the emergence of hadrons and nuclei from the underlying Standard Model of particle physics. He aims to determine the properties and interactions of these systems from first principles to confront experiment and to make predictions for regimes such as in the interior of neutron stars where experiments are not possible.
