What is the Origin of Nuclear Physics? Nuclear physics came into being after the discovery of atomic nucleus by Ernest Rutherford and his team in by the famous Rutherford experiment. The experiment gave surprising results.
Most of this matter is found at the core of atoms, the same atoms that comprise all we see around us including ourselves. Researchers seek to answer questions such as how the universe evolved just after the Big Bang from a super-hot plasma of quarks and gluons, how the different elements of the universe were formed, and how a nucleus is made up of individual protons and neutrons interacting with each other with the strongest force in Nature.
The protons and neutrons themselves are the basic bound states of quarks in the universe; how these states are formed from quarks interacting with the gluonic field described by Quantum Chromodynamics is still only poorly understood, and under active study.
Experimental Nuclear Physics Research Modern experimental research in this field uses high-energy acceleration of both protons and large nuclei, while much of modern theoretical research relies on high powered computational facilities to understand data and make detailed predictions.
The University of Colorado has active groups in both theoretical and experimental research in nuclear physics. My research is focused on the elucidation of how the basic constituents of the nucleon, quarks, are bound in a gluonic field.
At present, we still have only basic one-dimensional momentum distributions of the quarks and gluons. Recent advances, both experimental and theoretical, have opened the possibility of learning about the true three-dimensional structure.
Jamie Nagle Jamie Nagle: My current research is in the field of experimental high-energy heavy ion physics.
The current theory of strong interactions quantum chromodynamics QCD predicts that nuclear matter at high density higher than at the center of the Sun and high temperature hotter than at the center of the Sun will undergo a phase transition, where the quarks and gluons are no longer confined to individual nucleons.
The formation and experimental detection of such a state called the quark-gluon plasma or QGP is the primary objective of high-energy nuclear physics. Dennis Perepelitsa Dennis Perepelitsa: I study the properties of nuclear matter at extremely large temperatures and densities. In the first microsecond after the Big Bang, all the matter that would eventually become the observable Universe existed in a hot, dense, primordial Quark-Gluon Plasma QGP phase.
While we know that the strong nuclear interaction is governed by the theory of Quantum Chromodynamics, the QGP exhibits remarkable, non-intuitive behaviors which are not evident just from this fundamental theory.
My research utilizes ultra-relativistic collisions of heavy nuclei, first at the Large Hadron Collider and eventually at the Relativistic Heavy Ion Collider, to experimentally investigate the emergent properties of nuclear matter under extreme conditions. Theoretical Nuclear Physics Research Physicists in this field explore the nature of the strong force by studying the theory of Quantum Chromodynamics.
Unlike the quantum theory of electromagnetism, Quantum Chromodynamics has the property that the fundamental particles quarks and gluons interact more and more weakly when probed at higher and higher energy scales or temperatures.
This property of the theory is called asymptotic freedom. Quark-Gluon Plasma One interesting consequence of asymptotic freedom is that at some temper- ature, the interaction should be so weak that the fundamental particles no longer are bound con ned inside ordinary nuclei.
Above this temperature, matter is in a new phase of matter, called the quark-gluon plasma. Relativistic Hydrodynamics The experimental data from RHIC and the LHC strongly indicate that the quark-gluon plasma is an exceptionally good liquid, with a very small viscosity.
This motivates the theoretical study of the experimental results using fluid dynamic simulations. Since the energy involved in these experiments is very large, the fluid constituents are moving almost at the speed of light, making it necessary to use a fully relativistic version of hydrodynamics.
Neutron Stars Very high densities are similar to very high temperatures in the sense that the interaction of Quantum Chromodynamic becomes weak. The centers of neutron stars are expected to reach the highest particle densities in the universe, so it is possible that neutron stars harbor quark matter in their inner cores.
Studying the properties of neutron stars and comparing to observational data is also one of the research subject of theoretical nuclear physics.High Energy Physics; Nuclear Physics; The field of high energy physics is guided by intertwined science drivers to explore the elementary constituents of matter and energy, the interactions between them, and the nature of space and time.
