Professor’s Milestone in Nuclear Physics Seeks to Understand the Universe Itself

Early research on atomic nuclei yielded a wave of discoveries.

A nuclear physics professor from Florida International University was among a team of researchers that proposed something so out of this world, colleagues first hesitated to accept it was possible.

In 1993, they boldly predicted how the densest materials in the universe – known to exist only in rare neutron stars – could be made here on Earth. Ultimately, their research was published in Physical Review C, a leading academic journal focused on nuclear physics.

It spawned a wave of follow up research that in 2006 confirmed their prediction was true. For the tiniest sliver of a second, researchers at the Thomas Jefferson National Accelerator Facility in Virginia were able to briefly create the material that exists inside a neutron star.

“You are wrong many more times than you are right,” said Misak Sargsian, who joined FIU in 1998. “This was a rare case where the prediction was confirmed. That’s actually quite cool when you succeed.”

For its 50th anniversary, Physical Review Chighlighted research the journal’s editors consider milestones in nuclear physics. At the top of the list was the paper by Sargsian and his colleagues Donal Day, Leonid Frankfurt, and Mark Strikman.

At the root of this work lies the desire to understand the universe itself.

So much of the work of nuclear physicists focuses on atomic nuclei because they create mass and structure. Planets, stars, moons – even people – cannot exist without atomic nuclei. Understanding the nucleus of the atom helps us better understand the world and the worlds around us.
