Theoretical physicists studying the behavior of ultra-cold atoms have discovered a new source of friction, dispensing with a century-old paradox in the process. Their prediction, which experimenters may soon try to verify, was reported recently in Physical Review Letters.The friction afflicts certain arrangements of atoms in a Bose-Einstein Condensate (BEC), a quantum state of matter in which...

The idea of a pump is at least as old as the ancient Greek philosopher and scientist Archimedes. More than 2000 years ago, Archimedes allegedly invented a corkscrew pump that could lift water up an incline with the turn of a handle. Versions of the ancient invention still bear his name and are used today in agriculture and... Continue Reading

Quantum computers hold great potential, but they remain hard to build because their basic components—individual quantum systems like atoms, electrons or photons—are fragile. A relentless and noisy background constantly bombards the computer’s data. One promising theoretical approach, known as topological quantum computing, uses groups of special particles confined to a plane to combat this... Continue Reading

JQI Fellow Gretchen Campbell has been named the new NIST Co-Director of the Joint Quantum Institute, effective April 1, 2016. Campbell joined the JQI in 2009 and is also a UMD Adjunct Associate Professor and APS Fellow. In recent years she has received various accolades for her atomtronics research, including the APS Maria Goeppert-Mayer award. Campbell succeeds JQI Fellow Charles Clark, who... Continue Reading
Stephen Eckel is postdoctoral researcher at the JQI, and a National Research Council postdoctoral fellow from 2013-2014. After receiving his undergraduate degree in physics at Lehigh University, he received numerous fellowships and prizes while pursuing a PhD in physics at Yale. There, he performed two precision measurements searching for the electron’s electric dipole moment, one using a solid-state sample and another using molecular lead-oxide. At JQI, he works with Gretchen Campbell on creating superfluid analogs of superconducting quantum interference devices (SQuIDs) using Bose-Einstein condensates of sodium atoms. He is currently working with a team of graduate students to build a new experiment that can incorporate both ultra-cold sodium and erbium.
Ryan Barnett, a former JQI postdoctoral fellow at the Condensed Matter Theory Center (CMTC), is now a ‘Lecturer in Condensed Matter Theory’ (UK equivalent of assistant professor) at Imperial College in London. Ryan is a theoretical physicist interested in collective effects in ultracold atomic gases. While at the JQI his research focused on spinor condensates, non-equilibrium dynamics, and synthetic gauge fields. Much of his recent work at CMTC was motivated by ongoing experimental activities at the JQI.
Elizabeth Goldschmidt recently joined the quantum information science group at the Army Research Laboratory. She earned an undergraduate degree in physics at Harvard University. After, she went on to earn a PhD at JQI, where as part of Alan Migdall's research group, she worked on quantum memory and single photon technologies. She then received a National Research Council postdoctoral fellowship at NIST to work with Trey Porto on simulating condensed matter systems with ultracold atoms trapped in optical lattices. In her position at the Army Research Lab, she is starting a new experimental research program focused on quantum memory and quantum information in solid-state materials.
Paul Hess is a postdoctoral fellow at JQI. He received his undergraduate degree in astrophysics at Williams College and went on to get his PhD in physics at Harvard University. There, he worked on precision measurement experiments that searched for the electric dipole moment of electrons bound to thorium oxide molecules. At JQI, as part of Chris Monroe’s trapped ion team, his work revolves around examining complex many body systems. He has studied many-body localization and is currently working on an experiment that would simulate quantum solids with an increased number of trapped ions.
Stephen Powell, a former JQI postdoctoral fellow at CMTC, now works at the Nordic Institute of Theoretical Physics or Nordita in Stockholm, Sweden. His research in the group of Sankar Das Sarma centered around strongly correlated systems with a specific focus on frustrated magnetism and ultracold gases. At Nordita, he will continue this line of research, which is at the meeting point of condensed matter and atomic physics. In talking of his postdoctoral experience he says, “Something I've particularly enjoyed about being at JQI is having close contact with various experimental groups here.”
Crystal Senko was a graduate student in Chris Monroe's ion trapping group. While in the group she focused on ultrafast spin manipulation as well as quantum simulation of magnetism. She is now a postdoctoral researcher with Mikhail Lukin at Harvard. Senko is an undergraduate alumni of Duke University, where she worked with Dan Gauthier on magneto-optical trapping using distributed feedback lasers.
