Marvin Cohen

Marvin Cohen. He is an American theoretical physicist renowned for his foundational contributions to the understanding of the electronic properties of solids. A University Professor of Physics at the University of California, Berkeley, and a senior faculty scientist at the Lawrence Berkeley National Laboratory, his development of the empirical pseudopotential method revolutionized computational materials science. His work has profoundly impacted the study of semiconductors, superconductivity, and nanotechnology.

Early life and education

Born in Montreal, he moved with his family to Brooklyn, New York as a child. He completed his undergraduate studies in physics at the University of Chicago, earning a Bachelor of Science degree. For his graduate work, he attended the University of California, Berkeley, where he was advised by Nobel laureate John H. Van Vleck. His doctoral research laid the groundwork for his future investigations into the quantum mechanical behavior of materials, culminating in a Ph.D. in 1964.

Academic career

Following his doctorate, he joined the physics faculty at the University of California, Berkeley in 1965, where he has remained for his entire career. He also holds a long-term appointment as a senior faculty scientist at the Lawrence Berkeley National Laboratory, a key center for materials research. He has held numerous visiting professorships at institutions worldwide, including the Hebrew University of Jerusalem and the University of Cambridge. Throughout his tenure, he has mentored generations of prominent physicists and served in various leadership roles within the American Physical Society.

Research and contributions

His most celebrated achievement is the creation and application of the empirical pseudopotential method, a computational technique that simplifies the complex quantum mechanical problem of many interacting electrons in a solid. This method allowed, for the first time, accurate calculations of electronic band structures for real materials like silicon and germanium. He later pioneered the use of ab initio pseudopotentials derived from first principles, which became a cornerstone of modern computational materials science. His research group has made seminal predictions and analyses concerning superconductivity, the properties of carbon nanotubes, and novel two-dimensional materials, influencing fields from microelectronics to quantum computing.

Awards and honors

His scientific impact has been recognized with many of the highest honors in physics. He received the Oliver E. Buckley Condensed Matter Prize in 1979 and the Fritz London Memorial Prize in 1985 for his work on superconductivity. In 2001, he was awarded the National Medal of Science by President Bill Clinton. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and a fellow of the American Physical Society. He has also been honored with the Foresight Institute Richard P. Feynman Prize in Nanotechnology and the APS Aneesur Rahman Prize for Computational Physics.

Personal life

He is married and has children. An avid supporter of the arts and education, he has been involved in initiatives to promote science literacy. He maintains a deep connection to the academic community at Berkeley and is known as a dedicated mentor and colleague. His legacy extends beyond his publications through the widespread use of his computational methods and the continued work of his many students and collaborators across the globe.
