Ultracold Atom

With properties of a superfluid but with a crystalline structure, supersolids have previously only been observed in ultracold condensates—until now.

Scientists investigated a new two-dimensional form of matter known as Bose glass, which could help physicists study a concept known as many-body localization.

MIT physicists directly observed ultracold atoms in an "edge state," flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in materials that could enable super-efficient transmission of energy and data.

For the first time, MIT physicists have captured direct images of "second sound," the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of heat flow in superconductors and neutron stars.

MIT professor of physics Wolfgang Ketterle received a Vannevar Bush Faculty Fellowship to study quantum science and build new quantum devices using ultracold dysprosium atoms.

New experiments with ultra-cold atomic gases shed light on how all interacting quantum systems evolve after a sudden energy influx. New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a

Experiments that imitate solid materials with light waves reveal the quantum basis of exotic physical effects

If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material's own natural frequency can send its vibrations into overdrive, causing the glass to shatter.

The quantum realm of atomic particles is embedded with randomness. Still, precise control of quantum systems, such as quantum computers, is of great importance for modern quantum science and prospective quantum technology.

C60 molecules on a gold substrate appear more complex than their graphene counterparts, but have much more ordinary electronic properties. This is now shown by measurements with ARPES at BESSY II and detailed calculations.

NASA's Cold Atom Laboratory runs super-low-temperature experiments in near-zero gravity that would be impossible to accomplish on Earth.

The development of experimental platforms that advance the field of quantum science and technology (QIST) comes with a unique set of advantages and challenges common to any emergent technology. Researchers at Stony Brook University, led by Dominik Schneble, Ph.D., report the formation of matter-wave polaritons in an optical lattice, an experimental discovery that enables studies of a central QIST paradigm through…

The Royal Navy has successfully demonstrated the capabilities of ground-breaking cold atom technology.

China's 'father of quantum' Pan Jianwei and his team have been studying optical-lattice-based ultracold atomic systems since 2010.

Ultracold atoms show an unexpected ordering of magnetic moments.

What plagues quantum upscaling? Most quantum computing devices are dependent on using complex physical phenomena that are either very short-lived (~10-12 seconds) and/or only survive at ultra-low temperatures (e.g., 10-3 to 10-6 Kelvin) and/or require ultra-high vacuum environments, except possibly those using nitrogen vacancy centers in diamonds or color centers in silicon, silicon carbide, etc.

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. A team of physicists at Penn State showed that these gases immediately respond, "evolving" with features that are common to all "many-body" quantum systems thrown out of equilibrium in…

A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing—a method that can perform certain calculations significantly more efficiently than conventional computing.

Solids can be melted by heating, but in the quantum world it can also be the other way around: In a joint effort, an experimental team led by Francesca Ferlaino in Innsbruck, Austria, and a theoretical team led by Thomas Pohl in Aarhus, Denmark, show how a quantum liquid forms supersolid structures through heating. The scientists obtained a first phase diagram for a supersolid at finite temperature.

Universe's coldest fermions open a portal to high-symmetry quantum realm. Physicists from Japan and the U.S. used atoms about 3 billion times colder than interstellar space to open a portal to an unexplored realm of quantum magnetism. "Unless an alien civilization is doing experiments like these
