Next year, scientists expect to change the way we define the basic units with which we measure our universe. An article by scientists at the National Institute of Standards and Technology (NIST) written for teachers will help ensure high school physics students are hip to the news.The brief, six-page article, which appears in this month’s issue...

Optical fibers are the backbone of modern communications, shuttling information from A to B through thin glass filaments as pulses of light. They are used extensively in telecommunications, allowing information to travel at near the speed of light virtually without loss.These days, biologists, physicists and other scientists regularly use optical fibers to pipe light around inside their labs....

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...

Zachary Eldredge, a PhD student at JQI and QuICS, received undergraduate degrees in physics and mathematics from the University of Oklahoma. At JQI, he has studied the emergence of a self-organized structure in atoms near a nanofiber, working closely with Luis Orozco’s to investigate nanofiber platforms and cold atom physics. Now, he works with Alexey Gorshkov and studies the physics of long-range quantum information and quantum networks.
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.
Efim Rozenbaum is a graduate fellow at JQI who studied physics as an undergraduate and graduate student at St. Petersburg State University. His undergraduate thesis focused on new numerical methods for solving the equations that govern quantum systems with axial symmetry, and his Master’s thesis continued this work for highly charged heavy ions. Now, he works with JQI and the Condensed Matter Theory Center to study the effect of interactions on dynamical localization, the signatures of chaotic transitions in quantum dynamics and non-Markovian soliton dynamics with non-Ohmic friction.
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.
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.
Alexey V. Gorshkov
Alexey Gorshkov is a JQI fellow and theoretical physicist at NIST. 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.”
