\u201cNeutrons participate in all four fundamental forces of nature \u2013 and perhaps in undiscovered forces too \u2013 making them an ideal system for expanding our knowledge in fields spanning nuclear physics, particle physics, astrophysics and cosmology,\u201d Leung says. \u201cDespite being the most abundant subatomic particle on Earth, neutrons have remained elusive experimentally because of their lack of electric charge and limited lifetime outside the atom before decaying. However, these same properties make them an ideal testbed and probe for new science.\u201d<\/p>\n
The NSF CAREER grant builds on a five-year $436,000 grant Leung was awarded last September from the U.S. Department of Energy\u2019s Oak Ridge National Laboratory<\/a>, which supports equipment for research into the neutron\u2019s extremely small electric dipole moment, which has never been observed. The electric dipole moment is a measure of how electric charge is distributed within a neutron. Determining its value could shed light on fundamental problems in physics, including how more matter than antimatter was leftover after the Big Bang or the existence of new particles that might explain dark matter.<\/p>\n The research is performed as part of two collaborations: the neutron Electric Dipole Moment at the Spallation Neutron Source<\/a> and the Compton scattering at the High Intensity Gamma Ray Source. These collaborations combine the expertise of top scientists from universities and national laboratories spanning North America (22 institutes in the former and 10 in the latter) to work toward shared scientific goals. \u201cWhat I find exciting about my field is that I get to build state-of-the-art scientific instruments in my lab, take them to big particle accelerators across the country, analyze and pore over data with my collaborators \u2013 all to try to answer big questions about our universe,\u201d Leung says.<\/p>\n As part of this new program, Leung seeks to support students before, during and after their time at Montclair State University, offering research experiences in nuclear, particle and quantum physics to students who don\u2019t typically have such opportunities.<\/p>\n \u201cStudents from Bergen and other nearby community colleges will be offered funded summer research opportunities in Montclair\u2019s newly renovated nuclear physics lab to build skills, confidence and contacts at a four-year university,\u201d he says.<\/p>\n Part of the NSF CAREER grant will fund Montclair undergraduates conducting summer research at the Triangle Universities Nuclear Lab<\/a>, hosted by Duke University, as well as at the Oak Ridge and Los Alamos National Labs<\/a>. These national facilities are considered among the crown jewels of the nation\u2019s research and innovation ecosystem.<\/p>\n \u201cOur undergraduates will interact with graduate students and faculty from world-class universities, reducing their entry barrier for advanced degrees,\u201d says Leung. \u201cThrough their research, students will develop hands-on skills relevant to high-tech sectors such as cryogenics, medical imaging instrumentation, ultra-high vacuum technologies and quantum information science.\u201d<\/p>\n Sophomore Sarah Estupinan-Jimenez, who has been analyzing data on cryogenic liquid helium and hydrogen experiments as a research project, will conduct research at a particle accelerator at Duke University this summer. She will also participate in courses on nuclear and particle physics, career development and scientific communication alongside a cohort of a dozen students from across the country. She will then bring her newly acquired experiences and skills back to Montclair in the fall.<\/p>\n \u201cWe\u2019re looking to understand how nuclear matter interacts in nature, which makes up everything that exists around us,\u201d says Estupinan-Jimenez, who credits Leung with helping her get to a place to be able to earn the Duke research spot. \u201cHe really focuses us on going beyond what\u2019s required and pushing for excellence.\u201d<\/p>\n Eric Swanson, a sophomore Physics major, will be working at Oak Ridge National Laboratory in Tennessee this summer as part of a yearlong funded fellowship. He will further work he started with Leung on measuring protons in polymers containing different isotopes of hydrogen with nuclear magnetic resonance.<\/p>\n \u201cIt\u2019s a large joining effort to try to increase our ability to measure neutrons,\u201d which is an exciting prospect for Swanson, who wants to be a nuclear physicist some day.<\/p>\n In addition to his new research and student-mentoring program, Leung plans to launch a gen-ed course at Montclair State University titled \u201cPhysics for Future Presidents\u201d to introduce physics’ ability to address key societal challenges.<\/p>\n Junior Earth and Environmental Science major Tori Woznick, who is minoring in Physics, applied to work in the lab with Leung this summer after taking a physics course with him. She will be co-mentored by Assistant Chemistry Professor Amrita Sarkar this summer as a interdisciplinary effort on synthesizing the ultra-high purity polymers required in nuclear physics experiments.<\/p>\n \u201cHe genuinely cares about the students he teaches,\u201d she says. \u201cAnd I think it\u2019s going to be a great learning experience.\u201d<\/p>\n Students training with Leung in the nuclear physics lab are learning hands-on skills relevant to high-tech sectors that College of Science and Mathematics Dean Lora Billings says will be useful when they enter the workforce or continue with graduate studies.<\/p>\n \u201cDr. Leung is an academic role model who values both research and education, and we are proud of the work he is doing to include underrepresented students in the lab,\u201d Billings says. \u201cHis efforts are a wonderful example of how Montclair State University leads the way in providing access and excellence for students in STEM education.\u201d<\/p>\n Story by Editorial Director Laura Griffin<\/a>.
