Researchers develop new tool for analyzing large superconducting circuits

New research tools are needed to fully develop quantum computers and advance the field. Now researchers have developed and tested a theoretical tool for analyzing large superconducting circuits. These circuits use superconducting quantum bits, the smallest units of a quantum computer, to store information. Circuit size is important since protection from detrimental noise tends to come at the cost of increased circuit complexity. Currently there are few tools that tackle the modeling of large circuits.

Observation of quasi-equilibrium phase coexistence in supercritical fluids

A research team lays down the foundation for the expansion of supercritical fluid applications research.

Star attraction: Magnetism generated by star-like arrangement of molecules

A new study demonstrating the emergence of localized magnetism due to a 2D nanomaterial's unique, star-like atomic-scale structure has potential for applications in next-generation electronics based on organic nanomaterials, where tuning of electronic interactions can lead to a vast range of new electronic and magnetic phases.

Quantum materials cut closer than ever

A new method designs nanomaterials with less than 10-nanometer precision. It could pave the way for faster, more energy-efficient electronics.

Using acoustics to conceal and simulate objects

When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic sound effect—a specific acoustic field. This explains why the same piece of music sounds different when played in an old church or a modern concrete building.

Study provides evidence for 'new physics'

Is the Standard Model of particle physics incorrect at key points? Recently there has been an increase in experimental observations that deviate from the predictions of this widely accepted physical theory. A current study by the University of Bonn now provides even stronger evidence for the existence of "new physics." The final version of the paper is now published in the journal Physics Letters B. Lead author Chien-Yeah Seng will present the results in mid-October at the fall meeting of the U.S. Physical Society.

Engineering various sources of loss provides new features for perfect light absorption

Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses.

After 20 years of trying, scientists succeed in doping a 1D chain of cuprates

After 20 years of trying, scientists doped a 1D copper oxide chain and found a surprisingly strong attraction between electrons that may factor into the material's superconducting powers.

Groundbreaking technique yields important new details on silicon, subatomic particles and possible ‘fifth force’

Using a groundbreaking new technique, researchers has revealed previously unrecognized properties of technologically crucial silicon crystals and uncovered new information about an important subatomic particle and a long-theorized fifth force of nature.

Groundbreaking technique yields important new details on silicon, subatomic particles and possible 'fifth force'

Using a groundbreaking new technique at the National Institute of Standards and Technology (NIST), an international collaboration led by NIST researchers has revealed previously unrecognized properties of technologically crucial silicon crystals and uncovered new information about an important subatomic particle and a long-theorized fifth force of nature.
