Starting at the quark level, we have derived a theory of nuclear structure, that in its initial application appears extremely successful. The aim of this project is to advance this revolutionary new approach to the theory of nuclear structure to the next level by exploring its predictions for a number of outstanding questions in modern nuclear physics. This includes the properties of superheavy nuclei, with atomic number beyond 100, including the potential existence of a new region of stability and complementing experimental searches underway internationally to discover the limits of stability with large neutron or proton excess, which is crucial to understanding the origin of the elements and may contribute new energy related technology.Read moreRead less

Connecting Quantum Chromodynamics to experiment via non-perturbative effective field theory. This project aims to disclose the composition of proton excited states by advancing the theoretical formalism governing the underlying dynamics. At present, the structure of even the first excited state of the proton, the Roper, remains unknown for more than 50 years following its discovery.

This project aims to disclose the composition of proton excited states by advancing the theoretical formalism governing the underlying dynamics. At present, the structure of even the first excited state of the proton, the Roper, remains unknown for more than 50 years following its discovery. While the fundamental theory of Quantum Chromodynamics (QCD) describes the interactions between the quarks and gluons composing these states, the phenomena that emerge from QCD are complex and require dedicated analyses to understand them. The intended outcome is the creation of the effective field theory required to decipher QCD calculations.Read moreRead less
Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons.

The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a space-time lattice. Simulating fermions on a lattice has proved very challenging. This project will explore novel and innovative improved fermion algorithms for the general problem of gauge theories on the lattice.Read moreRead less

Excitation spectra of quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the interactions underpinning the excitations of QCD, as being investigated at international facilities.
Interplay of the forces of nature: electroweak and strong interactions.
