Cold Chaos

At sub-micro-kelvin temperatures atoms or molecules move so slowly that it is better to think of them as spread-out, wavelike things a micron or more across, many times larger than any putative bond length (typically sub-nanometer in size) that would characterize bound molecules. A new experiment conducted at the University of Innsbruck in Austria adds a new twist to this picture.

Up-Converted Radio

Ever worry about losing your mobile-phone reception? The problem is a weak microwave signal. A new approach to this important problem provides a clean, all-optical detection of microwaves and radiowaves featuring noise mitigation a thousand times better than existing methods.

Solitary Confinement

Atomic nuclei are governed by laws quite distinct from those that regulate atomic electrons, which constitute the outer part of atoms and which are immediately responsible for light, chemistry and thus life. Yet there are sporadic regions of contact between these disparate realms. JQI Adjunct Fellow Marianna Safronova and her collaborators have been exploring one area of nuclear-atomic overlap for the isotope thorium-229.

The Entropy of Nations

Adam Smith showed in his book "The Wealth of Nations" that a sort of "hidden hand" was at work in distributing income among the population. A new JQI study shows that distribution of energy among nations is thermodynamic in nature.

Quantum Gimbal

Theorists at the Joint Quantum Institute predict that for some elements a vortex of atoms can be produced which pivots around another sample of atoms at rest in the middle. Such a quantum gimbal has been observed in condensates of two atomic species but never before in a swarm of exclusively one type of atoms in a state of lowest energy.

Congratulations to the 2013 Nobel Prize recipients Higgs and Englert

The 2013 Nobel Prize in Physics was awarded “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”

People Profiles

  • Steven Olmshenck

    JQI alumnus Steven Olmshenck, JQI

    NRC postdoctoral fellow Steven Olmschenk will be joining the faculty at Denison University located in Granville, Ohio. Steve was a graduate student in Chris Monroe’s Trapped Ion Quantum Information group. For the last few years he has been a postdoc in the NIST Laser Cooling and Trapping Group. While at NIST he has worked on Trey Porto’s double-well optical lattice experiment. Upon moving to Dension he plans to build an ion trapping experiment. 

  • Gretchen Campbell, Fellow

    Campbell is a NIST JQI fellow and works in the Laser Cooling and Trapping group. In her atom circuits lab, reserachers probe Na BECs in toroidal traps. The goals of these experiments include studying superfluidity, as well as superfluid analogs to superconducting circuits. A second experiment with ultracold strontium is being built. She received a Ph.D from MIT in 2006, where she worked with Wolfgang Ketterle and Dave Pritchard. There, she used Rb BECs in optical lattices to study atom interferometry, nonlinear atom optics and the superfluid – Mott insulator phase transition. These experiments included the first direct observation of the atomic recoil momentum in dispersive media. More recently, she worked with Jun Ye on precision measurements and frequency metrology with an 87Sr optical lattice clock. 

  • Crystal Senko

    Crystal Senko is a graduate student in Chris Monroe's ion trapping group. While in the group she has focused on ultrafast spin manipulation as well as quantum simulation of magnetism. Senko is an undergraduate alumni of Duke University, where she worked with Dan Gauthier on magneto-optical trapping using distributed feedback lasers.

  • Stephen Powell

    JQI alumnus Stephen Powell, JQI

    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. He will help organize the Nordita program “Pushing the boundaries with cold atoms,” to be held in early 2013. 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.”

  • Mohammad Hafezi

    Hafezi is a senior research associate and works at the interface of condensed matter theory and quantum optics. The focus of his research is on theoretical and experimental investigations of artificial gauge fields and topological order in photonics systems. Such systems can be exploited as robust optical devices insensitive to disorder, which is the subject of his NSF Physics Frontier Center’s seed funding program. Moreover, in the presence of strong optical nonlinearity, such systems are expected to exhibit fractional quantum Hall physics, providing a platform for potentially observing anoynic statistics. He received his Ph.D. from Harvard in 2009 where he worked with Mikhail Lukin and Eugene Demler. There, he studied strongly correlated physics in AMO systems. In particular, he worked on the topological characterization of ultracold atoms in 2D and also non-equilibrium dynamics of strongly interacting photons in 1D.

  • Wes Campbell

    JQI alumnus Wes Campbell, JQI

    Wes Campbell will join the faculty at UCLA in the fall, where he plans to build up a lab to study cold molecules and trapped ions. His cold molecule research is an outgrowth of the NSF Physics Frontier Center’s seed funding program, here at JQI. The seed funding program is a competitive opportunity for postdocs to apply for PFC funding to support an independent project. Since 2008, Wes has been doing research in Chris Monroe’s trapped ion quantum information group. Wes was instrumental in constructing an experiment that focuses on ultrafast gates with ions. During the last year he has also worked on quantum simulations of magnetism with ion chains.
