Interview with Dale Van Harlingen, Professor of Physics at the University of Illinois, Urbana-Champaign. He recounts his childhood in Ohio and his undergraduate education at OSU in physics and his early work on SQUIDS. Van Harlingen discusses his mentor Jim Garland, and he explains his decision to stay at OSU for graduate school to develop SQUID devices to make phase-sensitive measurements. He explains the opportunities that gained him a postdoctoral appointment at the Cavendish Laboratory in Cambridge where he developed his expertise in the Josephson Effect, and where he met John Clarke, who offered him a subsequent postdoctoral position at UC Berkeley. Van Harlingen describes his foray using SQUIDS to push the quantum limit, and he explains his decision to join the faculty at Illinois, where he was impressed both with the quality of the research and how nice everyone was. He describes joining the Materials Research Laboratory and the development of the Micro and Nanotechnology Laboratory, and he conveys his admiration for Tony Leggett. Van Harlingen discusses his research in NMR microscopy, grain boundary junctions, scanning tunneling microscopy, vortex configurations, and he describes his current interest in unconventional superconductors. At the end of the interview, Van Harlingen conveys his excitement about the national quantum initiative as a major collaboration between universities and National Labs, and he explains his motivation to understand if Majorana fermions actually exist.

Interview with Vyacheslav Romanov, Research Physical Scientist at the National Energy Technology Laboratory. Romanov recounts his upbringing in the Urals region of the Soviet Union, and he describes his education at a special high school for gifted students in Moscow. He explains the circumstances that led to his enrollment at the Moscow Institute of Physics and Technology for graduate school and his dawning realization that one can make sense of the world through physics. Romanov discusses his thesis research on the kinetics of light-matter interactions, and he describes his postgraduate work for the Soviet Space Program to develop thin film solar cells to power the International Space Station. He discusses the collapse of science funding after the breakup of the USSR and the opportunity he saw to emigrate to the United States at part of the Symposium on Diplomacy and Global Affairs in Washington, D.C. Romanov explains why he got an MBA from Waynesburg College and how this program put him on the path to U.S. citizenship. After a stint in the materials science industry, he describes his PhD research in physical chemistry and spectroscopy at the University of Pittsburgh, and how this led to his employment at NETL, first as a postdoc and then as a full-time employee. Romanov explains his initial work in geology and data analysis, his subsequent work in optimizing power plant generation, and his current research in reducing the environmental footprint of energy systems with machine learning. He describes the political and economic ramifications of his research, and he explains why carbon-based energy is central to the transition to a de-carbonized future, which, he asserts, will take decades to realize. At the end of the interview, Romanov explains why global efforts to mitigate environmental energy problems must rely on successful cooperation between the U.S. and China. 

Interview with Renata Wentzcovitch, professor of Applied Physics and Applied Mathematics and Earth and Environmental Sciences at Columbia University. Wentzcovitch recounts her childhood in Brazil, and she describes how her grandfather sparked her interest in science early on. She describes her education at the University of São Paulo’s Institute of Physics where she developed an interest in density functional theory. Wentzcovitch discusses her interest in pursuing a graduate degree in the United States, and her decision to attend UC Berkeley and study under the direction of Marvin Cohen. She describes her thesis research on pseudopotential plane-wave codes and super-hard materials such as boron nitride and diamonds. Wentzcovitch explains the impact of High Tc Superconductivity on both her career and the field generally, and she describes her postdoctoral research with joint appointments at Brookhaven and Stony Brook on evolving electronic wavefunctions via classical dynamics. She discusses her subsequent work with Volker Henie at Cambridge to study silicate perovskite, which in turn led to her first faculty appointment at the University of Minnesota. Wentzcovitch describes the importance of Minnesota’s Supercomputing Institute for her research, and she explains how her research focused more centrally on geophysics and the thermo-elasticity of minerals and their aggregates. She describes the founding of the Virtual Laboratory for Earth and Planetary Materials and explains her decision to join the faculty at Columbia and her involvement with VLab and the study of exchange-correlation functionals to address electronic interactions. At the end of the interview, Wentzcovitch discusses her current work on developing codes for thermodynamic computations and seismic tomography, and she conveys the value of pursuing international collaborations to fit her broad and diverse research agenda.

Interview with Lu Sham, Distinguished Professor of Physics Emeritus, University of California at San Diego. Sham recounts his childhood in Hong Kong and he describes the legacy of Japanese rule from World War II. He describes his early interests in math and he explains his decision to pursue a higher education in England at Imperial College. Sham discusses his motivation to conduct graduate work at Cambridge University and to study under Nevill Mott on the first principle method calculating the electron contribution to lattice vibration. He describes the help provided by John Ziman to secure his postdoctoral position at UC San Diego to work with Walter Kohn, and he describes the foundational collaboration and research that went into the Kohn-Sham equation and how this work builds on the classic debate between Einstein and Bohr. He describes the opportunities leading to his faculty appointment and eventual tenure on the physics faculty, and he explains the benefits of spending summers doing research at Bell Labs. Sham discusses his contributions to research on semiconductors, quantum computing, and density-functional theory. He describes his more recent interest in optics and the formative work he has done with graduate students and postdoctoral researchers over the years. Sham discusses his administrative service as department chair and Dean of Science. At the end of the interview, Sham asserts that the future of condensed matter physics holds limitless possibilities, and that improvements in semiconductor materials will push quantum information abilities in exciting and unforeseen directions.

Interview with Margaret Murnane, professor of physics at the University of Colorado, Boulder, fellow at JILA, and director of the NSF STROBE Science and Technology Center.
