JQI at DAMOP

The June 2-6, 2014 meeting of the American Physical Society’s Division of Atomic, Molecular, and Optical Physics (DAMOP) is one of the best showings of JQI research during the entire year. The following papers with JQI authors will be presented at the meeting in Madison, Wisconsin.

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

  • Alexey V. Gorshkov

    Alexey Gorshkov is a JQI fellow and theoretical physicist at NIST. He grew up in Moscow until his parents brought him to Boston when he was in 10th grade. In high school, he was good at math, so that's what he was planning to do in college, but then math ended up being too dry. Physics offered a perfect alternative since it involved lots of interesting mathematics and grappled with problems related to real life.

    He attended Harvard for his undergraduate and graduate degrees, obtaining a physics PhD in 2010 studying under Mikhail Lukin. After that he was a postdoctoral fellow at Caltech, working with John Preskill. He won numerous university teaching and research awards during these years.

    His research is at the intersection of AMO physics, condensed matter physics, and quantum information science. He has authored dozens of papers and has a patent entitled: “Scalable Room Temperature Quantum Information Processor.”

  • Ryan Barnett

    JQI alumnus Ryan Barnett, JQI

    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 was motivated by ongoing experimental activities at the JQI. In addition to continuing this line of research, he will teach Mathematical Physics during the 2012-2013 academic year.

  • 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.

  • Phil Richerme

    Phil Richerme is a postdoc in Chris Monroe's Trapped Ion Quantum Information Group. He studies quantum magnetism using a well-controlled and well-isolated system of atomic ion spins, realizing Feynman's original proposal for a quantum simulator. These experiments probe the ground state and dynamical evolution of interacting spin systems, which are difficult (or impossible) for classical computers to calculate for even a few dozen spins. Phil received his Ph.D. from Harvard in 2012, working with Gerald Gabrielse and the ATRAP collaboration at CERN to trap antihydrogen atoms for sensitive tests of CPT symmetry.

  • 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.
