How do we connect fundamental physics to forefront
experiments?
With new science waiting to be discovered at the Facility for
Rare Isotope Beams (FRIB) and the dawning of the era of
exascale supercomputing, this is a profound challenge and
opportunity for nuclear theory. The Lee Research Group
works to understand the nature and origins of matter by
crafting new approaches that link quantum chromodynamics
and electroweak theory to precise predictions for nuclear
structure and reactions relevant to the FRIB science mission.
One of the methods we have developed with collaborators
is lattice effective field theory. Effective field theory (EFT)
is an organizing principle for the interactions of a complex
system at low energies. When applied to low-energy
protons and neutrons in a formulation called chiral effective
field theory, it functions as an expansion in powers of the
nucleon momenta and the pion mass. Lattice EFT combines
this theoretical framework with lattice methods and Monte
Carlo algorithms that are applicable to few-body systems,
heavier nuclei, and infinite matter. The Lee Research Group
is part of the Nuclear Lattice EFT Collaboration, which has
been pioneered many of the theoretical ideas and methods
now being used in nuclear lattice simulations.
Nuclear lattice simulations
Some of the topics we are studying are superfluidity, nuclear
clustering, nuclear structure from first principles calculations,
ab initio scattering and inelastic reactions, thermodynamics
and phases of nuclear matter, and properties of nuclei as
seen through electroweak probes.
We are also applying new technologies and computational
paradigms such as eigenvector continuation, machine
learning tools to find hidden correlations, and quantum
computing algorithms for the nuclear many-body problem.
We are looking to work with experimentalists and theorists
on new ideas and creative ways to collaborate. If you are
interested in working in or with our group, please email
