Mapping battery materials with atomic precision

An international team used advanced techniques in electron microscopy to show how the ratio of materials that make up a lithium-ion battery electrode affects its structure at the atomic level, and how the surface is very different from the rest of the material.

Seeing is believing: Precision atom qubits achieve major quantum computing milestone

A unique approach to creating quantum bits from precisely positioned individual atoms in silicon is reaping major rewards, with scientists showing for the first time that they can make two of these atom qubits 'talk' to each other. The team has the ability to see the exact position of their qubits in the solid state.

Physicists tune a spin diode

A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change the resistance and the resonant frequency of the diode. In addition, this approach triples the range of frequencies on which the device can rectify alternating current. At the same time, the sensitivity of the spin diode is comparable to that of its semiconductor analogs. The paper was published in Physical Review B.

Einstein letter fetches $100,000 at Jerusalem auction

A letter penned by legendary physicist Albert Einstein discussing one of his groundbreaking theories sold in Jerusalem Tuesday for over $100,000 as part of trove of documents that went under the hammer.

Reshaping energy landscape of phonons in nanocrystals

Phonons, which are packets of vibrational waves that propagate in solids, play a key role in condensed matter and are involved in various physical properties of materials. In nanotechnology, for example, they affect light emission and charge transport of nanodevices. As the main source of energy dissipation in solid-state systems, phonons are the ultimate bottleneck that limits the operation of functional nanomaterials.

Physicists lay groundwork to better understand the birth of the universe

Scientists have developed the first techniques for describing the thermodynamics of very small systems with very high energy -- like the universe at the start of the Big Bang -- which could lead to a better understanding of the birth of the universe and other cosmological phenomena.

Media Invited to Upcoming Launch of NASA’s Newest Planet-Hunting Spacecraft

Media accreditation now is open for the launch of a NASA spacecraft that will search for planets outside of our solar system with a field of view almost 400 times larger than that of the agency’s Kepler mission.

Handwritten Einstein note up for auction in Jerusalem

For Albert Einstein, it turns out the law of attraction was relative.

Straightforward technique allows for accurate computer simulations of calcium signaling

Calcium is essential for our bodies to function. Calcium ions enable cells to communicate with one another, allowing neurons to interact, muscles to contract, and the heart's muscle cells to synchronize and beat. To better understand these processes, in which calcium ions interact with biological molecules such as proteins, researchers often use computer simulations. But accurate models are challenging and computationally expensive.
