Reference excerpt

Gretchen K. Campbell (born c. 1980) is an American atomic, molecular, and optical physicist associated with the National Institute of Standards and Technology. She works in the field of atomtronics and has received awards in recognition of her research contributions on Bose-Einstein condensates. She is currently on detail to the White House Office of Science and Technology Policy (WHOSTP), where she is the Assistant Director for Quantum Information Science at WHOSTP, and Director of the National Quantum Coordination Office (NQCO).

Early life and education Campbell was raised in western New York state and was curious about science from a young age. She attended Wellesley College for her undergraduate degree, initially intending to train as a veterinarian. However, first-year physics lectures by Glenn Stark and lab mentorship from Theodore W. Ducas shifted her interest toward physics. In particular, she enjoyed the physics problem-solving approach which encouraged logic and reasoning rather than memorisation. Her undergraduate honours thesis was on the topic of optical tweezers. She graduated from Wellesley in 2001, then moved to MIT for her PhD. She studied Bose-Einstein condensates in optical lattices and related quantum phase transitions. She finished her degree in 2007 under the supervision of Wolfgang Ketterle and David Pritchard.

Career and research Between 2007 and 2009, Campbell was a postdoctoral fellow at JILA in the group of Jun Ye. She worked on some of the world's most accurate atomic clocks based on optical transitions of cooled neutral atoms confined by optical lattices. In 2009, she moved to become a fellow of the Joint Quantum Institute (JQI) affiliation between NIST and the University of Maryland. She became co-director of the institute in 2016. She is part of the Laser Cooling and Trapping group and the Quantum Measurement Division. Campbell manages two laboratories through the JQI collaboration, one at NIST and one on the university campus. Campbell currently works in atomtronics, an emerging research area into circuitry based on a flow of atoms rather than electrons. She is a leader in the field, with experiments showing promise for applications in sensing or quantum computers. This technology draws on her expertise with Bose-Einstein condensates (BEC) by using sodium BEC rings to create superfluid atom circuits analogous to superconductors. These experiments are quantum in nature, as the rotation velocity of the ring trap flow is quantized. Using a laser to "stir" the BEC can cause transitions between eigenstates. Her contributions have included designing a weak link as an additional circuit component and observation of hysteresis effects. She enjoys conducting impactful, tabletop, ultracold experiments. Her work on BEC may also have implications for research on the early universe. BEC can be described as a "vacuum state for phonons" similar to the quantum field vacuum preceding early universe expansion. Campbell and her collaborator Stephen Eckel are interested to see if their model can provide insight into Hubble friction when a sound wave perturbs the BEC. Campbell mentors young scientists and manages a group for women in physics at the JQI. She was involved in the 2020 Conference for Undergraduate Women in Physics which took place there.

Awards and honours 2015 Fellow of the American Physical Society "for pioneering contributions to the study of superfluidity in atomic-gas Bose-Einstein condensates using ring-shaped condensates." 2015 Finalist, Emerging Leaders category of the Samuel J. Heyman Service to America Medals. She "advanced the emerging field of physics known as atomtronics, paving the way for a new generation of technologies much like electronics has transformed our society today." 2015 IUPAP Young Scientist Prize. 2015 Maria Goeppert Mayer Award "for her pioneering contributions to the study of superfluidity in atomic gas Bose-Einstein condensates using ring-shaped condensates, realizing atomic analogs to superconducting and superfluid liquid circuitry, including the use of weak links to create the first closed circuit atomtronic devices." 2012 Arthur S. Flemming Award. 2012 PECASE Award. She was recognised for her research excellence and her commitment to mentoring young scientists, especially women in physics. 2011 Department of Commerce Bronze Medal "for proving the feasibility of atomtronics, a new field of atom-based electronics, by demonstrating the first controllable atom circuit." 2008 Finalist DAMOP thesis prize of the American Physical Society. 2006 Martin Deutsch Prize For Excellence in Experimental Physics, MIT. 2005 OSA New Focus/Bookham Student Award. 2001 Phyllis Fleming Physics Prize.

Personal life Campbell has a daughter who was born in 2015.

Worked examples

Example 1 — a first encounter with Gretchen Campbell

Start with the simplest possible case. Write down what Gretchen Campbell claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gretchen Campbell before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gretchen Campbell ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gretchen Campbell

In research: Gretchen Campbell appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gretchen Campbell in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gretchen Campbell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women, American quantum physicists, American women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Gretchen Campbell outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
