Since the 1930s, scientists have relied on particle accelerators to delve into the mysteries of matter and the fundamental laws of physics. Today, these advanced machines, propelled by supercomputers, are enabling researchers to study the interactions and properties of the smallest particles known to humankind. This blog article explores how supercomputers, particularly the Oak Ridge Leadership Computing Facility‘s IBM AC922 Summit supercomputer, are aiding nuclear physicists in unraveling the secrets of quark interactions and revolutionizing our understanding of subatomic matter.
The Power of Particle Accelerators: Particle accelerators have played a crucial role in advancing our knowledge of matter. By propelling particles at nearly the speed of light and colliding them, scientists can study the resulting interactions and the particles formed. These powerful experimental tools provide insights into the structure of matter and the laws that govern our universe.
Probing the Secrets of Quarks: One of the primary focuses of large particle accelerators is understanding hadrons, which are subatomic particles composed of quarks. Quarks, the smallest known particles, carry fractional electric charges. Although scientists have a good understanding of how quarks constitute hadrons, studying the properties of individual quarks has been challenging due to their confinement within hadrons.
Lattice Quantum Chromodynamics (LQCD) and Supercomputing: By leveraging the computational capabilities of the IBM AC922 Summit supercomputer at Oak Ridge, a team of nuclear physicists led by Kostas Orginos at the Thomas Jefferson National Accelerator Facility and William & Mary has made significant progress in measuring quark interactions within hadrons. They employed a computational technique called lattice quantum chromodynamics (LQCD), which represents space-time as a lattice, enabling simulations of quark and gluon fields. This approach, combined with the tremendous computing power of Summit, allows for accurate modeling of close-to-physical mass quarks.
Bridging Theoretical Knowledge and Experimental Data: Traditionally, scientists have had limited information about the energy and momentum of quarks inside a proton. The team’s simulations, conducted with quarks close to their physical masses, provide a more complete picture. These simulations, combined with experimental data from upcoming particle collider experiments, such as the Electron-Ion Collider (EIC) at Brookhaven National Laboratory, enable scientists to make better predictions about subatomic matter.
Applications and Implications: Understanding individual quark properties has far-reaching implications. It enhances scientists’ ability to predict the interactions between quarks and particles like the Higgs boson, which plays a crucial role in giving mass to matter. Additionally, this knowledge aids in comprehending phenomena governed by weak force, such as radioactive decay.
Advancements in Algorithmic Techniques: The success of these simulations at physical quark masses is attributed to algorithmic advancements, including the implementation of multigrid solvers and efficient software libraries like QUDA. The combination of these improvements with cutting-edge hardware capabilities paves the way for further breakthroughs in particle physics research.
Conclusion: Thanks to the power of supercomputers like the IBM AC922 Summit, scientists are pushing the boundaries of particle physics research. By employing lattice quantum chromodynamics simulations and studying quark interactions in hadrons, researchers are gaining unprecedented insights into the fundamental particles that make up our universe. These advancements not only deepen our understanding of matter but also pave the way for future discoveries and applications in various fields of science and technology.
