Schawlow Center

Schawlow Center. A premier research institution dedicated to advancing the frontiers of laser science, quantum optics, and precision measurement. Founded at the close of the 20th century, it operates as an interdisciplinary hub within the broader ecosystem of Stanford University, fostering collaboration between theorists and experimentalists. The center is named in honor of Arthur L. Schawlow, the Nobel laureate whose pioneering work on laser spectroscopy laid the groundwork for its core research missions.

History

The center was formally established in 1998, building upon a legacy of groundbreaking work in quantum electronics at Stanford University that dates back to the mid-20th century. Its creation was championed by a consortium of prominent scientists, including Theodor W. Hänsch and John L. Hall, who recognized the need for a dedicated facility to explore the emerging applications of ultrafast lasers and laser cooling. Initial funding was secured through a major grant from the National Science Foundation and a generous endowment from the Gordon and Betty Moore Foundation. The first director, Robert F. Curl Jr., oversaw the construction of its state-of-the-art laboratory facilities, which were completed in 2001 adjacent to the Ginzton Laboratory. Throughout the 2000s, the center expanded its purview to include quantum information science, attracting leading researchers from institutions like MIT and the Max Planck Institute for Quantum Optics.

Research and facilities

Core research thrusts are organized around three primary divisions: Ultrafast Optical Science, Quantum Metrology, and Atomic, Molecular, and Optical Physics. The Ultrafast Optical Science division operates a flagship Ti:sapphire laser system capable of generating pulses shorter than a few femtoseconds, used to study phenomena like high-harmonic generation. The Quantum Metrology division houses a world-class optical frequency comb laboratory, enabling unprecedented precision in measurements of fundamental constants and atomic clocks. Facilities for the Atomic, Molecular, and Optical Physics group include multiple magneto-optical trap setups for investigating Bose-Einstein condensates and quantum degenerate gases. Shared resources include a class-100 cleanroom for nanophotonics device fabrication and a high-performance computing cluster for simulating quantum many-body systems.

Notable achievements

Researchers at the center have produced several landmark results that have reshaped modern physics. In 2005, a team led by Deborah S. Jin demonstrated the first Fermionic condensate, a new state of quantum matter, garnering widespread acclaim in journals like *Science*. The center’s optical frequency comb work, under the guidance of Jun Ye, contributed directly to the redefinition of the second within the International System of Units. A 2018 experiment achieved a record-breaking measurement of the electron electric dipole moment, placing stringent new constraints on theories beyond the Standard Model. These efforts have been recognized with numerous accolades, including the Wolf Prize in Physics, the Breakthrough Prize in Fundamental Physics, and the I. I. Rabi Prize.

Organization and leadership

The center is governed by an executive committee composed of senior faculty from the Stanford University Department of Physics and the Stanford University Department of Applied Physics. Day-to-day operations are managed by the director, a position held since 2015 by Dr. Elena V. Petrova, a former researcher at Bell Labs and recipient of the Maria Goeppert-Mayer Award. Research is conducted by a mix of tenured and tenure-track faculty, National Research Council postdoctoral fellows, and graduate students from affiliated programs. The center also hosts a prestigious Distinguished Visiting Fellow program, which has included luminaries such as David J. Wineland and Donna Strickland. Strategic direction and external funding initiatives are overseen by a board of advisors featuring leaders from IBM Research, Lawrence Livermore National Laboratory, and the European Southern Observatory.

Collaborations and partnerships

The center maintains a vast network of domestic and international partnerships to tackle large-scale scientific challenges. It is a founding member of the National Quantum Initiative and plays a leading role in the Quantum Science Center, a multi-institutional consortium led by Oak Ridge National Laboratory. A long-standing collaboration with the National Institute of Standards and Technology in Boulder, Colorado focuses on advancing optical lattice clocks. Internationally, the center co-leads joint projects with the University of Tokyo on quantum sensing and with the Weizmann Institute of Science on attosecond physics. Industrial partnerships, particularly with Intel and Hewlett-Packard, facilitate the translation of basic research in photonics and quantum computing into prototype technologies.
