Yale University

In this interview, David Zierler, Oral Historian for AIP, interviews Thomas Appelquist, Eugene Higgins Professor of Physics at Yale University. Appelquist recounts his upbringing in rural Iowa and then Indiana, where he attended Catholic high school. He describes his undergraduate experience at Illinois Benedictine College and explains his attraction to attend a small school for college. Appelquist discusses his decision to attend Cornell for his PhD, and recalls that, relative to others in his cohort who went to larger schools, he had the most catching up to do in quantum mechanics. He explains the development of his thesis topic under the direction of Don Yennie, which focused on aspects of renormalization theory using the Feynman parametric approach. Appelquist contextualizes some of the broader questions in quantum field theory and quantum electrodynamics at this time, and he describes the opportunities that led him to SLAC for his postdoctoral research. He describes his interests there as focused on theories of the weak interactions, and he describes his initial faculty appointment at Harvard where he joined the particle theory group led by Shelly Glashow and Sidney Coleman. Appelquist discusses his close collaboration with Helen Quinn on how to renormalize Yang-Mills theories, and he explains his decision to take a tenured position at Yale in consideration of the culture at Harvard, where the prospects of tenure were minimal. He describes the revolutionary discoveries of asymptotic freedom, QCD, and the “November Revolution” at SLAC and Brookhaven at the time. Appelquist describes his research and administrative activities to advance the particle theory group at Yale, and his overall efforts to improve the department as chair and in particular building up the condensed matter theory group. He discusses his tenure as Dean of the Graduate School and his long-term involvement with the Aspen Center. At the end of the interview, Appelquist describes his current interests in lattice gauge theory and explains why he expects that physics will see double beta decay in the next generation of experiments.

Interview with Robert Schoelkopf, Sterling Professor of Applied Physics and Physics at Yale, and director of the Yale Quantum Institute. Schoelkopf describes the origins of the Quantum Institute and the longer history of quantum research at Yale, and he recounts his childhood in Manhattan and then in Chappaqua as the son of art dealers. He describes his early interests in science and tinkering, and his undergraduate education at Princeton where he worked with Steve Boughn and Jeff Kuhn in the gravity group. Schoelkopf discusses his job at the Goddard Space Flight Center before beginning graduate work at Caltech. He describes his research under the direction of Tom Phillips in detector development for astrophysical applications and Josephson junctions, and he explains his ambition to focus on developing devices. Schoelkopf discusses his postdoctoral research at Yale to work with Dan Prober on mesascopic physics, and he explains his involvement in microwave research for quantum information and his explorations into the limits of electrometry. He discusses the opportunities that led to his faculty appointment at Yale, his involvement in building qubits and what this would portend for the future of quantum information. Schoelkopf describes the formative influence of Michel Devoret and Steve Girvin and he explains how these collaborations contributed to upending some aspects of theoretical quantum information. He describes how qubit research has matured over the past twenty years and how this research has contributed to industry and commercial ventures, but why he remains focused on basic science within a university setting. At the end of the interview, Schoelkopf predicts some of the practical contributions that true quantum computing can offer society and why he is excited about the next generation of quantum information scientists.

Interview with Herman B. White, physicist at Fermi National Accelerator Laboratory. White recounts his childhood in Tuskegee, Alabama and growing up during segregation. He discusses his early interests in science and his decision to enroll at Earlham College in Indiana as an undergraduate. White then describes his time at Michigan State University as a graduate student, during which he also held a position as a resident research associate at Argonne National Laboratory. Dr. White talks about his transition from nuclear physics to particle physics upon completing his master’s degree at MSU. He discusses the events that led him to accept a position at Fermilab rather than immediately pursue a PhD. White was the first African-American scientist appointed at Fermilab, and he recounts his early years there being mentored by Raymond Stefanski. He then describes his research fellowship at Yale and his non-traditional path to getting a PhD in 1991 from Florida State University. White talks about returning to Fermilab to work on kaon physics, and his eventual involvement in the Tevatron experiment. Toward the end of the interview, White reflects on the changes and trends he has seen in the research being done at Fermilab over the years, as well as his involvement in the National Society of Black Physicists.

Interview with William Marciano, Senior Physicist at Brookhaven National Laboratory. Marciano recounts his upbringing in Brooklyn and his early interests in science, and he describes his undergraduate work at RPI and then NYU. He explains his decision to remain at NYU for his graduate research to study under the direction of Alberto Sirlin, and his thesis research on dimensional regularization. Marciano discusses his postdoctoral appointment at Rockefeller University where he worked on the SU(5) model of Grand Unification, and the opportunities that led to his promotion there to a faculty position. He explains his short tenure at Northwestern before joining Brookhaven, where kaon physics was taking center stage, and where ISABELLE was being built. Marciano discusses the origins of the Lab's g-2 experiment, and he compares the demise of ISABELLE to that of the SSC, for which he served on the program advisory committee. He describes the success of RHIC, and he discusses his research focus on muon and neutrino physics for the Lab's AGS program. Marciano explains his proposal that led to DUNE at Fermilab and he surveys his long record of advisory work for the HEPAP community and how the United States has contributed to the LHC. He reflects on winning the Sakurai prize and his contributions in establishing the validity of the Standard Model at the level of its quantum corrections. Marciano describes his recent work in dark physics, and he surveys the current state of play in muon physics and the Intensity Frontier. At the end of the interview, Marciano compares the diffuse network of the U.S. National Lab system to the centrality of CERN in Europe, and he explains why his work on DUNE and CP violation has been so personally meaningful.

David Zierler interviews Larry Gladney, professor of physics and Dean of Diversity and Faculty Development at Yale. He describes the origins of this Dean position, and how he worked to make STEM a more inclusive, accepting place over the course of his career. He recounts his childhood in East St. Louis, opportunities that led to an undergraduate education at Northwestern, where he developed interests in experimental physics. He explains the attraction of being recruited to Stanford; Burt Richter invited him to work at SLAC. He describes his thesis research under the direction of John Jaros and Bob Hollebeek, looking for supersymmetric electrons. Gladney discusses postdoctoral research at Penn, where he worked with Brig Williams on the CDF project. He also goes into the excitement surrounding the search for the top quark at Fermilab. He describes joining Penn’s faculty, while also getting involved in diversity promotion within/beyond the physics department. He then discusses contributions to the BaBar collaboration and he explains the interest of particle physicists moving into cosmological research, at the turn of the century. Gladney describes his time as the department chair at Penn and his work on LIGO and the LSST, and he discusses the state of play in high-energy physics in the post-SSC environment. At the end, he surveys some of the most promising research in cosmology and why engaging young students is so crucial for the future of the field.
