Atomic beltway could solve problems of cosmic gravity
When is a traffic jam not a traffic jam? When it's a quantum traffic jam, of course. Only in quantum physics can traffic be standing still and moving at the same time. A new theoretical paper from scientists at the National Institute of Standards and Technology (NIST) and the University of Maryland suggests that intentionally creating just such a traffic jam out of a ring of several thousand...

Artificial atoms shed light on the future of security
From credit card numbers to bank account information, we transmit sensitive digital information over the internet every day. Since the 1990s, though, researchers have known that quantum computers threaten to disrupt the security of these transactions. That’s because quantum physics predicts that these computers could do some calculations far faster than their conventional counterparts. This... Continue Reading
Move over, lasers: Scientists can now create holograms using neutrons
- October 20, 2016
- Research News
For the first time, a team including scientists from the National Institute of Standards and Technology (NIST) and JQI have used neutron beams to create holograms of large solid objects, revealing their interior details in ways that ordinary holograms do not.Holograms—flat images that look like three-dimensional objects—owe their striking look to interfering waves. Both matter and light behave... Continue Reading
L'Oréal-UNESCO award goes to former JQI student researcher
Karina Jiménez-García, a former visiting graduate student who worked with JQI Fellow Ian Spielman, was one of 30 young women scientists to receive a 2016 L'Oréal-UNESCO For Women in Science fellowship. She was selected from a pool of more than 1,000 applicants and received the award for her ongoing research on the quantum behavior of... Continue Reading
For decades, particle accelerators have grabbed headlines while smashing matter together at faster and faster speeds. But in recent years, alongside the progress in high-energy experiments, another realm of physics has been taking its own exciting strides forward.That realm, which researchers call condensed matter physics, studies chunks of matter moving decidedly slower than the protons in...

Physics Nobel honors underpinnings of exotic matter
A trio of researchers who laid the foundation for understanding numerous exotic phases of matter have split the 2016 Nobel Prize in Physics.The Royal Swedish Academy of Sciences awarded the prize "for theoretical discoveries of topological phase transitions and topological phases of matter" to three laureates: David Thouless of the University of Washington, Duncan Haldane of Princeton...

The JQI community joins our colleagues at JILA and NIST in mourning the loss of Deborah Jin, a pioneer in the physics of ultracold gases, an area of research that joins condensed matter and atomic physics. Jin was an outstanding scientist, colleague, and mentor. To learn more about Jin's life, research and accomplishments, please read the remembrances by ... Continue Reading
This Fall, theoretical condensed matter physicist Maissam Barkeshli joined the UMD Department of Physics as an Assistant Professor and a JQI Fellow. In 2010 he received a PhD from MIT under the supervision of Xiao-Gang Wen. Since then he has been a Simons Postdoctoral Fellow at Stanford University (2010-2013) and a postdoctoral researcher at Microsoft's Station Q, located at UC Santa Barbara (... Continue Reading
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.
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.”
Hafezi is JQI fellow 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.
Mary Lyon is originally from Princeton, New Jersey. She attended Bryn Mawr College, where she earned both her undergraduate degree in physics and a high school teaching certificate. Lyon originally planned to be a high school physics teacher, but discovered a love for research during a summer program at MIT the summer after her junior year. She briefly taught high school in Columbus, GA before going to graduate school at Brigham Young University, where she worked with Scott Bergeson on strongly coupled ultracold neutral plasmas. She is currently a JQI postdoctoral researcher in the group of Trey Porto and Steve Rolston where she is building a new quantum information experiment that will use an ensemble of cold Rydberg atoms.
Former NRC postdoctoral fellow Steven Olmschenk is currently faculty at Denison University located in Granville, Ohio. Steve was a graduate student in Chris Monroe’s Trapped Ion Quantum Information group and then a postdoc in the NIST Laser Cooling and Trapping Group. While at NIST he worked on Trey Porto’s double-well optical lattice experiment. At Dension he has a group researching physics at the interface of quantum optics and trapped atomic ions http://personal.denison.edu/~olmschenks/.
Nicholas Grabon is a JQI graduate fellow who received an undergraduate degree in physics at the University of Wisconsin-Madison. There, he helped design silicon chips with embedded quantum logic. At JQI, he previously worked on the theory of topological states on a lattice containing individual sites. Now, he is working with Vladimir Manucharyan to build smaller resonators with higher quality, design (fluxonium) qubits with decreased noise and better understand many-body physics.
