In the vast expanse of the Universe, there exist extreme places where the laws of physics are pushed to their limits. Magnetars, the compacted cores of neutron stars, harbor magnetic fields that reach an astonishing strength of around 100 trillion gauss. However, researchers have uncovered hints of even more powerful magnetic fields right here on Earth. By studying particle interactions at the Relativistic Heavy Ion Collider (RHIC) at the US Department of Energy’s (DOE) Brookhaven National Laboratory, scientists have detected traces of record-breaking magnetic fields embedded in the debris produced by colliding heavy ions.
One of the critical findings from this analysis is the interaction of magnetic fields with the quark-gluon plasma (QGP). Quarks, the building blocks of protons and neutrons, exist fleetingly within this plasma, constantly interacting with gluon particles. Through observing these interactions, physicists gain valuable insights into the fundamental forces at play within atomic nuclei. By understanding how quarks and antiquarks interact within nuclear particles, scientists can unravel the mysteries of matter at its most basic level.
The concept of the chiral magnetic effect offers a possible way to map the behavior of quarks and antiquarks within the QGP. However, the fleeting nature of the electromagnetic field within this chaotic environment poses challenges to direct observation. Despite this, physicists hypothesized that off-center collisions between heavy nuclei could generate immensely powerful magnetic fields, rivaling those of magnetars. These collisions would result in charged protons spiraling in a vortex, creating a magnetic eddy with strengths surpassing any known in the Universe.
The magnetic fields generated by these collisions are predicted to reach an astonishing 10^18 gauss, far surpassing the strength of even the most powerful magnetar. These ephemeral bursts of magnetism, lasting only fractions of a second, leave a significant impact on the surrounding particles. By analyzing the remnants of these collisions, researchers were able to identify the pathways taken by particles, revealing crucial information about the electrical conductivity of the quark-gluon plasma.
The measurements conducted at the RHIC shed light on the complex interactions within atomic nuclei, offering a deeper understanding of the behavior of quarks and gluons in extreme conditions. By deciphering the mysteries of record-breaking magnetic fields on a microscopic scale, scientists are paving the way for advancements in particle physics and the exploration of fundamental forces that govern the Universe.
