Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This is especially true of atomtronics, a relatively new science devoted to creating artificial tailored materials consisting of neutral atoms held in an array with laser beams, or atoms moving along a desired track under electric or magnetic influence

(PhysOrg.com) -- A team of physicists from the Joint Quantum Institute (JQI), the Neils Bohr Institute in Copenhagen, Denmark, and Harvard University has developed a theory describing how to both detect weak electrical signals and cool electrical circuits using light and something very like a nanosized loudspeaker.

(PhysOrg.com) -- Scientists at the Joint Quantum Institute (JQI) have for the first time engineered and detected the presence of high angular momentum collisions between atoms at temperatures close to absolute zero. Previous experiments with ultracold atoms featured essentially head-on collisions. The JQI experiment, by contrast, is able to create more complicated collisions between atoms using only lasers

September is commonly the month where things begin to gather pace again, and in the world of fusion energy research, things are no different. European scientists working on the Joint European Torus (JET), the world's largest magnetic confinement fusion device, are about to embark on the first round of experiments following a 22-month period where the device was out of action whilst being upgraded and commissioned.

Surprisingly, transmitting information-rich photons thousands of miles through fiber-optic cable is far easier than reliably sending them just a few nanometers through a computer circuit. However, it may soon be possible to steer these particles of light accurately through microchips because of research performed at the Joint Quantum Institute of the National Institute of Standards and Technology (NIST) and the University of Maryland, together with Harvard University.

Two prominent advisers to the Joint Chiefs of Staff think adopting social and environmental change is the best path to maintaining America's global hegemony.

(PhysOrg.com) -- Researchers from the National Institute of Standards and Technology and the University of Maryland have created the first nontrivial "atom circuit," a donut-shaped loop of ultracold gas atoms circulating in a current analogous to a ring of electrons in a superconducting wire. The circuit is "nontrivial" because it includes a circuit element—an adjustable barrier that controls the flow of atom current to specific allowed values. The newly published work was done at the Joint Quantum Institute, a NIST/UM collaboration.

(PhysOrg.com) -- Completing the story they started by creating synthetic magnetic fields, scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields.

Big companies enter into joint ventures—new business entities created through business agreements—all the time. In fact, many large companies now rely on partnering up with other companies, especially smaller ones, as a way to innovate by outsourcing their research and development efforts. "Companies can't do it on their own anymore," says Dr
