个人简介
I study Quantum Chromodynamics(QCD), the fundamental theory of the strong force. This force binds quarks and gluons together to form protons and neutrons, the fundamental building blocks of matter that make up our world. In principle, QCD describes all of nuclear physics, in the sense that Quantum Electrodynamics describes solid state physics. It is also important to particle physics because most of the particles detected in high-energy collider experiments like those at the Large Hadron Collider at CERN are hadrons, the bound states of quarks and gluons.
QCD is a relativistic quantum field theory which describes the interactions of the gluons and quarks. Because the strength of the QCD interaction is intrinsically large, QCD is extremely difficult to solve. Practical calculations, e.g. to predict the mass of the proton, are done through large scale numerical simulations of the QCD vacuum– a technique known as lattice QCD since space-time is discretized on a four dimensional lattice to make the calculations sensible. These calculations are performed on the world’s biggest supercomputers. My colleagues in the RBC/UKQCD Collaboration and I perform computations on super-clusters at Fermilab and Jefferson Lab and supercomputers at Argonne and Brookhaven National Labs.
