# Robert James Thompson
**Robert James Thompson** (known as Rob Thompson) is an atomic physicist at NASA's Jet Propulsion Laboratory (JPL) who works on laser-cooled and degenerate quantum gases, and who developed the original mission concept and high-level design for the Cold Atom Lab, the first multi-user facility for studying ultracold atoms in space.[1](https://science.nasa.gov/people/robert-thompson/) • [2](http://arxiver.lazybrains.com/author/369726) He serves as Program Scientist for Cold Atom Research in NASA's Fundamental Physics Office, and his current research interests are degenerate quantum gases in microgravity, space-based quantum sensors, cavity quantum dynamics, and optical clocks.[1](https://science.nasa.gov/people/robert-thompson/)

## Education and career
Thompson earned his B.S. at [Georgia Tech](https://www.edgepedia.org/georgia-tech) from 1980 to 1984 and his Ph.D. at the [University of Texas at Austin](https://www.edgepedia.org/university-of-texas-at-austin) from 1988 to 1994, with Jeff Kimble as thesis advisor.[1](https://science.nasa.gov/people/robert-thompson/) His doctoral work produced the 1992 [Physical Review Letters](https://www.edgepedia.org/physical-review-letters) paper on normal-mode splitting, co-authored with Gerhard Rempe and Harry J. Kimble, which observed the normal-mode splitting of an atom coupled to an optical cavity.[1](https://science.nasa.gov/people/robert-thompson/)
He worked as a postdoctoral researcher with Bill Phillips, the 1997 Nobel laureate in physics, at the [National Institute of Standards and Technology](https://www.edgepedia.org/national-institute-of-standards-and-technology), from June 1994 to April 1997.[1](https://science.nasa.gov/people/robert-thompson/) In March 1997 he joined JPL in Pasadena, where he established the laboratory's laser cooling and ultracold-atom program and has worked since, with more than thirty years of research experience in atomic and molecular physics.[1](https://science.nasa.gov/people/robert-thompson/) Since January 2002 he has also been an adjunct associate professor at ArtCenter College of Design, which lists him as Senior Scientist at JPL and Project Scientist for the [Cold Atom Laboratory](https://www.edgepedia.org/cold-atom-laboratory), an [International Space Station](https://www.edgepedia.org/international-space-station) experiment studying gases at temperatures close to absolute zero.[3](https://www.artcenter.edu/about/get-to-know-artcenter/people/detail.html?accdID=0104562)
## Research contributions
**The Cold Atom Lab.** Thompson developed the original mission concept and high-level design for the Cold Atom Lab (CAL), which launched to the International Space Station in May 2018 and has operated since as the world's first multi-user facility for studying ultracold atoms in space.[1](https://science.nasa.gov/people/robert-thompson/) • [2](http://arxiver.lazybrains.com/author/369726) By the time of a later mission abstract, CAL had traveled more than 5 A.U. around the Earth and performed over 100,000 individual cold-atom measurements, operated remotely from JPL.[4](https://science.nasa.gov/wp-content/uploads/2023/05/47_641e3690c1a7a413c37050c81717ebd0_ThompsonRobertJ1.pdf) Documented accomplishments include detailed observations of Bose-Einstein condensation in microgravity, delta-kick cooling, "extreme adiabatic cooling," cold atoms in spherical shell ("bubble") geometries, and atom interferometry.[4](https://science.nasa.gov/wp-content/uploads/2023/05/47_641e3690c1a7a413c37050c81717ebd0_ThompsonRobertJ1.pdf) A key technical achievement was demonstrating that astronauts can repair and upgrade complex cold-atom systems in orbit.[4](https://science.nasa.gov/wp-content/uploads/2023/05/47_641e3690c1a7a413c37050c81717ebd0_ThompsonRobertJ1.pdf)
**Dual-species work and quantum sensing.** CAL produced the first simultaneous dual-species Bose-Einstein condensate in space, formed from ⁸⁷Rb and ⁴¹K, observed interspecies interactions, and produced ³⁹K ultracold gases, a step toward quantum tests of the Universality of Free Fall.[2](http://arxiver.lazybrains.com/author/369726) The CAL atom interferometer was also used to remotely measure the photon recoil of the atom-interferometer laser, a demonstration of the first quantum sensor using matter-wave interferometry in space, with Ramsey shear-wave interference observable over 150 ms of free expansion.[2](http://arxiver.lazybrains.com/author/369726) CAL condensates have been created and manipulated expanding with energies of a few tens of picokelvin, with observation times over a few seconds and temperatures below 100 pK achievable in microgravity.[2](http://arxiver.lazybrains.com/author/369726)
His earlier JPL record includes work on cold-atom beam sources and interferometry: a compact high-efficiency cold atom beam source (Applied Physics B), longitudinal coherence in cold atom interferometry (Journal of Modern Optics, 2007), spinor dynamics-driven formation of a dual-beam atom laser ([Optics Express](https://www.edgepedia.org/optics-express), 2006), and generation of an intense cold-atom beam from a pyramidal magneto-optical trap.[5](https://academictree-staging.thetransmitter.org/physics/publications.php?pid=93468)
## Collaborations and identity
Disambiguation matters for this name. A prominent Thompson Group at JILA ([University of Colorado Boulder](https://www.edgepedia.org/university-of-colorado-boulder)) works on dynamical phase transitions, entangled matterwave interferometers, and [superradiant lasers](https://www.edgepedia.org/superradiant-laser); it is unrelated to the JPL scientist.[6](https://www.colorado.edu/jila/thompson) [INSPIRE-HEP](https://www.edgepedia.org/inspire-hep) also maintains a separate author profile (ID 1961472) for a "Richard J. Thompson" associated with cold-atom works such as "Exploring the limits of ultracold atoms in space," illustrating how bibliographic databases split or mislabel records among physicists named R. J. Thompson.[7](https://inspirehep.net/authors/1961472)
## Recent developments
Thompson remains active. A 2023 Nature paper (volume 623, pages 502 to 508) reported quantum gas mixtures and dual-species atom interferometry in space with him among the authors.[5](https://academictree-staging.thetransmitter.org/physics/publications.php?pid=93468)
