Research In Our Group

Solid Polarized Targets:

We are unique among university based research groups as we have the capability to develop, build, and maintain the cryogenic polarized targets critical for investigating spin physics and helicity correlations. We focus primarily on high cooling power evaporation systems and low temperature frozen spin systems. We are also heavily involved in target material research and optimizing polarization techniques improving the overall figure of merit in large scale scattering experiments.

Spin Physics and Polarized Observables:

The group focuses on studies of spin effects in highly polarized proton, neutron, and deuteron targets. These polarized scattering experiments use the world-class solid polarized targets, which are developed and tested right here in our Lab. We concentrate on experiments that use spin degrees of freedom (i.e. using polarized targets and beams) with photon, electron, and nucleon beams on nucleon targets to extract new information about the properties of the fundamental building blocks of nature.

Nuclear and Particle Physics Experiments:

We are interested in a wide energy range and have projects and affiliations at Fermi National Accelerator Facility, Dukes Triangle Universities Nuclear Laboratory, Jefferson National Accelerator Facility, Los Alamos National Labs, and Oak Ridge National Labs. (See our Experiments)

Theory and Phenomenology in Nuclear and Medium Energy:

We are involved in studying the quark and gluon structure of hadrons. Our group works with the nuclear theory group researching techniques to exploit helicity correlations using machine learning to support our experimental effort. We are interested in the quark and gluon structure of nuclei including generalized parton and transverse momentum distributions.

Theory and Computational in Nuclear Spin Dynamics:

We are involved in theoretical research of the polarization mechanisms in solid materials at low temperature. This work requires modeling different aspects of dynamic nuclear polarization and nuclear magnetic resonance for the purpose of optimizing and measuring bulk spin alignment in a variety of materials. We are also developing simulations of these mechanisms which can be used to better understand spin dynamics in a variety of field and temperature conditions. This research can be used to improve the overall figure of merit of helicity sensitive particle physics experiments.
