Floquet engineering tunes ultracold molecule interactions and produces two-axis twisting dynamics

Floquet engineering tunes ultracold molecule interactions and produces two-axis twisting dynamics

Pulse sequences for generating two-axis twisting rotate the spins of KRb molecules, transforming the spin exchange interactions. Credit: Steven Burrows/Ye Group The interactions between quantum spins underlie some of the universe’s most interesting phenomena, such as superconductors and magnets. However, physicists have difficulty engineering controllable systems in the lab that replicate these interactions. Now, in … Read more

Scientists discover crude oil decimates sea otter buoyancy

Scientists discover crude oil decimates sea otter buoyancy

Credit: Pixabay/CC0 Public Domain Sea otters are famed for their luscious pelts, but the fur almost led to their extinction. By 1938, only a tiny population of ~50 remained clinging to the central California coast. Since then, the mammals have battled back. However, the charismatic creatures are still at risk from crude oil spilled by … Read more

Over two-million acres of floodplain development occurred in US in last two decades, study finds

Credit: Armen Agopian, University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science A nationwide analysis of community-level floodplain development found that over two-million acres of floodplain were developed over the past two decades across the United States, with roughly half of all new floodplain housing built in Florida. These findings from scientists at … Read more

Tech billionaire emerges from capsule in 1st civilian spacewalk in history – National

A silhouetted figure stands in stark contrast against the bright blue of planet Earth, his torso emerging from a space capsule hundreds of kilometres above the atmosphere. The man is Jared Isaacman, a tech billionaire who became the first civilian in history to perform a commercial spacewalk. Before today, the only people who could attempt … Read more

Colorado mining town’s polluted legacy has a potential for profit, but some are wary of the risk

LEADVILLE, Colo. — Rust-colored piles of mine waste and sun-bleached wooden derricks loom above the historic Colorado mountain town of Leadville — a legacy of gold and silver mines polluting the Arkansas River basin more than a century after the city’s boom days. Enter a fledgling company called CJK Milling that wants to “remine” some … Read more

Quantum researchers cause controlled ‘wobble’ in the nucleus of a single atom

Quantum researchers cause controlled ‘wobble’ in the nucleus of a single atom

Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of … Read more
